| Parameters || |---|---| | `base` | `Context`
| ## Public methods ### bindIsolatedService Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindIsolatedService (Intent service, int flags, String instanceName, Executor executor, ServiceConnection conn) ``` Variation of `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` that, in the specific case of isolated services, allows the caller to generate multiple instances of a service from a single component declaration. In other words, you can use this to bind to a service that has specified `https://developer.android.com/reference/android/R.attr#isolatedProcess` and, in addition to the existing behavior of running in an isolated process, you can also through the arguments here have the system bring up multiple concurrent processes hosting their own instances of that service. The instanceName you provide here identifies the different instances, and you can use `https://developer.android.com/reference/android/content/Context#updateServiceGroup(android.content.ServiceConnection,%20int,%20int)` to tell the system how it should manage each of these instances.
| Parameters || |---|---| | `service` | `Intent`: Identifies the service to connect to. The Intent must specify an explicit component name. This value cannot be `null`.
| | `flags` | `int`: Operation options for the binding as per `https://developer.android.com/reference/android/content/ContextWrapper#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)`.
| | `instanceName` | `String`: Unique identifier for the service instance. Each unique name here will result in a different service instance being created. Identifiers must only contain ASCII letters, digits, underscores, and periods. This value cannot be `null`.
| | `executor` | `Executor`: Callbacks on ServiceConnection will be called on executor. Must use same instance for the same instance of ServiceConnection. This value cannot be `null`. Callback and listener events are dispatched through this `https://developer.android.com/reference/java/util/concurrent/Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `https://developer.android.com/reference/android/content/ContextWrapper#getMainExecutor()`. Otherwise, provide an `https://developer.android.com/reference/java/util/concurrent/Executor` that dispatches to an appropriate thread.
| | `conn` | `ServiceConnection`: Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.
| | Returns || |---|---| | `boolean` | Returns success of binding as per `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)`.
| ### bindService Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindService (Intent service, int flags, Executor executor, ServiceConnection conn) ``` Same as `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.ServiceConnection,%20int)` with executor to control ServiceConnection callbacks. This method only accepts a 32 bits flag, to pass in a 64 bits flag, call `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` instead.

| Parameters || |---|---| | `service` | `Intent`: This value cannot be `null`.
| | `flags` | `int`: Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Context#BIND_AUTO_CREATE` - `https://developer.android.com/reference/android/content/Context#BIND_DEBUG_UNBIND` - `https://developer.android.com/reference/android/content/Context#BIND_NOT_FOREGROUND` - `https://developer.android.com/reference/android/content/Context#BIND_ABOVE_CLIENT` - `https://developer.android.com/reference/android/content/Context#BIND_ALLOW_OOM_MANAGEMENT` - `https://developer.android.com/reference/android/content/Context#BIND_WAIVE_PRIORITY` - `https://developer.android.com/reference/android/content/Context#BIND_IMPORTANT` - `https://developer.android.com/reference/android/content/Context#BIND_ADJUST_WITH_ACTIVITY` - `https://developer.android.com/reference/android/content/Context#BIND_NOT_PERCEPTIBLE` - `https://developer.android.com/reference/android/content/Context#BIND_ALLOW_ACTIVITY_STARTS` - `https://developer.android.com/reference/android/content/Context#BIND_INCLUDE_CAPABILITIES` - `https://developer.android.com/reference/android/content/Context#BIND_SHARED_ISOLATED_PROCESS` - `https://developer.android.com/reference/android/content/Context#BIND_PACKAGE_ISOLATED_PROCESS` - `https://developer.android.com/reference/android/content/Context#BIND_EXTERNAL_SERVICE` | | `executor` | `Executor`: Callbacks on ServiceConnection will be called on executor. Must use same instance for the same instance of ServiceConnection. This value cannot be `null`. Callback and listener events are dispatched through this `https://developer.android.com/reference/java/util/concurrent/Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `https://developer.android.com/reference/android/content/ContextWrapper#getMainExecutor()`. Otherwise, provide an `https://developer.android.com/reference/java/util/concurrent/Executor` that dispatches to an appropriate thread.
| | `conn` | `ServiceConnection`: This value cannot be `null`.
| | Returns || |---|---| | `boolean` | The result of the binding as described in `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.ServiceConnection,%20int)`.
| ### bindService Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindService (Intent service, ServiceConnection conn, Context.BindServiceFlags flags) ``` See `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.ServiceConnection,%20int)` Call `https://developer.android.com/reference/android/content/Context.BindServiceFlags#of(long)` to obtain a BindServiceFlags object.
| Parameters || |---|---| | `service` | `Intent`: This value cannot be `null`.
| | `conn` | `ServiceConnection`: This value cannot be `null`.
| | `flags` | `Context.BindServiceFlags`: This value cannot be `null`.
| | Returns || |---|---| | `boolean` |
| ### bindService Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindService (Intent service, ServiceConnection conn, int flags) ``` Connects to an application service, creating it if needed. This defines a dependency between your application and the service. The given conn will receive the service object when it is created and be told if it dies and restarts. The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed. If the service does not support binding, it may return `null` from its `https://developer.android.com/reference/android/app/Service#onBind(android.content.Intent)` method. If it does, then the ServiceConnection's `https://developer.android.com/reference/android/content/ServiceConnection#onNullBinding(android.content.ComponentName)` method will be invoked instead of `https://developer.android.com/reference/android/content/ServiceConnection#onServiceConnected(android.content.ComponentName,%20android.os.IBinder)`. **Note:** This method *cannot* be called from a `https://developer.android.com/reference/android/content/BroadcastReceiver` component. A pattern you can use to communicate from a BroadcastReceiver to a Service is to call `https://developer.android.com/reference/android/content/Context#startService(android.content.Intent)` with the arguments containing the command to be sent, with the service calling its `https://developer.android.com/reference/android/app/Service#stopSelf(int)` method when done executing that command. See the API demo App/Service/Service Start Arguments Controller for an illustration of this. It is okay, however, to use this method from a BroadcastReceiver that has been registered with `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)`, since the lifetime of this BroadcastReceiver is tied to another object (the one that registered it). This method only accepts a int type flag, to pass in a long type flag, call `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.ServiceConnection,%20android.content.Context.BindServiceFlags)` instead.

| Parameters || |---|---| | `service` | `Intent`: Identifies the service to connect to. The Intent must specify an explicit component name. This value cannot be `null`.
| | `conn` | `ServiceConnection`: Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.
| | `flags` | `int`: Operation options for the binding. Can be: - 0 - `https://developer.android.com/reference/android/content/Context#BIND_AUTO_CREATE` - `https://developer.android.com/reference/android/content/Context#BIND_DEBUG_UNBIND` - `https://developer.android.com/reference/android/content/Context#BIND_NOT_FOREGROUND` - `https://developer.android.com/reference/android/content/Context#BIND_ABOVE_CLIENT` - `https://developer.android.com/reference/android/content/Context#BIND_ALLOW_OOM_MANAGEMENT` - `https://developer.android.com/reference/android/content/Context#BIND_WAIVE_PRIORITY` - `https://developer.android.com/reference/android/content/Context#BIND_IMPORTANT` - `https://developer.android.com/reference/android/content/Context#BIND_ADJUST_WITH_ACTIVITY` - `https://developer.android.com/reference/android/content/Context#BIND_NOT_PERCEPTIBLE` - `https://developer.android.com/reference/android/content/Context#BIND_INCLUDE_CAPABILITIES`
| | Returns || |---|---| | `boolean` | `true` if the system is in the process of bringing up a service that your client has permission to bind to; `false` if the system couldn't find the service or if your client doesn't have permission to bind to it. Regardless of the return value, you should later call `https://developer.android.com/reference/android/content/Context#unbindService(android.content.ServiceConnection)` to release the connection.
| ### bindService Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindService (Intent service, Context.BindServiceFlags flags, Executor executor, ServiceConnection conn) ``` See `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20int,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` Call `https://developer.android.com/reference/android/content/Context.BindServiceFlags#of(long)` to obtain a BindServiceFlags object.
| Parameters || |---|---| | `service` | `Intent`: This value cannot be `null`.

| ### bindServiceAsUser Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean bindServiceAsUser (Intent service, ServiceConnection conn, int flags, UserHandle user) ``` Binds to a service in the given `user` in the same manner as `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)`. Requires that one of the following conditions are met: - caller has `android.Manifest.permission.INTERACT_ACROSS_USERS_FULL` - caller has `android.Manifest.permission.INTERACT_ACROSS_USERS` and is the same package as the `service` (determined by its component's package) and the Android version is at least `https://developer.android.com/reference/android/os/Build.VERSION_CODES#TIRAMISU` - caller has `android.Manifest.permission.INTERACT_ACROSS_USERS` and is in same profile group as the given `user` - caller has `android.Manifest.permission.INTERACT_ACROSS_PROFILES` and is in same profile group as the given `user` and is the same package as the `service`

| Parameters || |---|---| | `service` | `Intent`: Identifies the service to connect to. The Intent must specify an explicit component name. This value cannot be `null`.

| ### createConfigurationContext Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createConfigurationContext (Configuration overrideConfiguration) ``` Return a new Context object for the current Context but whose resources are adjusted to match the given Configuration. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight.
| Parameters || |---|---| | `overrideConfiguration` | `Configuration`: A `https://developer.android.com/reference/android/content/res/Configuration` specifying what values to modify in the base Configuration of the original Context's resources. If the base configuration changes (such as due to an orientation change), the resources of this context will also change except for those that have been explicitly overridden with a value here. This value cannot be `null`.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | A `https://developer.android.com/reference/android/content/Context` with the given configuration override.

| ### createContextForSplit Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createContextForSplit (String splitName) ``` Return a new Context object for the given split name. The new Context has a ClassLoader and Resources object that can access the split's and all of its dependencies' code/resources. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same split) may be so the Context itself can be fairly lightweight.
| Parameters || |---|---| | `splitName` | `String`: The name of the split to include, as declared in the split's `AndroidManifest.xml`.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | A `https://developer.android.com/reference/android/content/Context` with the given split's code and/or resources loaded.
| | Throws || |---|---| | `https://developer.android.com/reference/android/content/pm/PackageManager.NameNotFoundException` | | ### createDeviceContext Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createDeviceContext (int deviceId) ``` Returns a new `Context` object from the current context but with device association given by the `deviceId`. Each call to this method returns a new instance of a context object. Context objects are not shared; however, common state (such as the `https://developer.android.com/reference/java/lang/ClassLoader` and other resources for the same configuration) can be shared, so the `Context` itself is lightweight. Applications that run on virtual devices may use this method to access the default device capabilities and functionality (by passing `https://developer.android.com/reference/android/content/Context#DEVICE_ID_DEFAULT`. Similarly, applications running on the default device may access the functionality of virtual devices. Note that the newly created instance will be associated with the same display as the parent Context, regardless of the device ID passed here.

| Parameters || |---|---| | `deviceId` | `int`: The ID of the device to associate with this context.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | This value cannot be `null`.
| ### createDeviceProtectedStorageContext Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createDeviceProtectedStorageContext () ``` Return a new Context object for the current Context but whose storage APIs are backed by device-protected storage. On devices with direct boot, data stored in this location is encrypted with a key tied to the physical device, and it can be accessed immediately after the device has booted successfully, both *before and after* the user has authenticated with their credentials (such as a lock pattern or PIN). Because device-protected data is available without user authentication, you should carefully limit the data you store using this Context. For example, storing sensitive authentication tokens or passwords in the device-protected area is strongly discouraged. If the underlying device does not have the ability to store device-protected and credential-protected data using different keys, then both storage areas will become available at the same time. They remain as two distinct storage locations on disk, and only the window of availability changes. Each call to this method returns a new instance of a Context object; Context objects are not shared, however common state (ClassLoader, other Resources for the same configuration) may be so the Context itself can be fairly lightweight.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` |
| ### createDisplayContext Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createDisplayContext (Display display) ``` Returns a new `Context` object from the current context but with resources adjusted to match the metrics of `display`. Each call to this method returns a new instance of a context object. Context objects are not shared; however, common state (such as the `https://developer.android.com/reference/java/lang/ClassLoader` and other resources for the same configuration) can be shared, so the `Context` itself is lightweight. **Note:** This `Context` is **not** expected to be updated with new configuration if the underlying display configuration changes and the cached `Resources` it returns could be stale. It is suggested to use `https://developer.android.com/reference/android/hardware/display/DisplayManager.DisplayListener` to listen for changes and re-create an instance if necessary. This `Context` is **not** a UI context, do not use it to access UI components or obtain a `https://developer.android.com/reference/android/view/WindowManager` instance. To obtain an instance of `https://developer.android.com/reference/android/view/WindowManager` configured to show windows on the given display, call `https://developer.android.com/reference/android/content/Context#createWindowContext(int,%20android.os.Bundle)` on the returned display context, then call `https://developer.android.com/reference/android/content/Context#getSystemService(java.lang.String)` or `https://developer.android.com/reference/android/content/Context#getSystemService(java.lang.Class)` on the returned window context.

| Parameters || |---|---| | `display` | `Display`: The display to which the current context's resources are adjusted. This value cannot be `null`.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | A context for the display.
| ### createPackageContext Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createPackageContext (String packageName, int flags) ``` Return a new Context object for the given application name. This Context is the same as what the named application gets when it is launched, containing the same resources and class loader. Each call to this method returns a new instance of a Context object; Context objects are not shared, however they share common state (Resources, ClassLoader, etc) so the Context instance itself is fairly lightweight. Throws `https://developer.android.com/reference/android/content/pm/PackageManager.NameNotFoundException` if there is no application with the given package name. Throws `https://developer.android.com/reference/java/lang/SecurityException` if the Context requested can not be loaded into the caller's process for security reasons (see `https://developer.android.com/reference/android/content/Context#CONTEXT_INCLUDE_CODE` for more information}.
| Parameters || |---|---| | `packageName` | `String`: Name of the application's package.
| | `flags` | `int`: Option flags. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Context#CONTEXT_INCLUDE_CODE` - `https://developer.android.com/reference/android/content/Context#CONTEXT_IGNORE_SECURITY` - `https://developer.android.com/reference/android/content/Context#CONTEXT_RESTRICTED` | | Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | A `https://developer.android.com/reference/android/content/Context` for the application.
| | Throws || |---|---| | `https://developer.android.com/reference/android/content/pm/PackageManager.NameNotFoundException` | | ### createWindowContext Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context createWindowContext (int type, Bundle options) ``` Creates a Context for a non-activity window. A window context is a context that can be used to add non-activity windows, such as `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY`. A window context must be created from a context that has an associated `https://developer.android.com/reference/android/view/Display`, such as `https://developer.android.com/reference/android/app/Activity` or a context created with `https://developer.android.com/reference/android/content/Context#createDisplayContext(android.view.Display)`. The window context is created with the appropriate `https://developer.android.com/reference/android/content/res/Configuration` for the area of the display that the windows created with it can occupy; it must be used when `https://developer.android.com/reference/android/view/LayoutInflater` views, such that they can be inflated with proper `https://developer.android.com/reference/android/content/res/Resources`. Below is a sample code to **add an application overlay window on the primary display:** ``` ... final DisplayManager dm = anyContext.getSystemService(DisplayManager.class); final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY); final Context windowContext = anyContext.createDisplayContext(primaryDisplay) .createWindowContext(TYPE_APPLICATION_OVERLAY, null); final View overlayView = Inflater.from(windowContext).inflate(someLayoutXml, null); // WindowManager.LayoutParams initialization ... // The types used in addView and createWindowContext must match. mParams.type = TYPE_APPLICATION_OVERLAY; ... windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams); ``` This context's configuration and resources are adjusted to an area of the display where the windows with provided type will be added. **Note that all windows associated with the same context will have an affinity and can only be moved together between different displays or areas on a display.** If there is a need to add different window types, or non-associated windows, separate Contexts should be used. Creating a window context is an expensive operation. Misuse of this API may lead to a huge performance drop. The best practice is to use the same window context when possible. An approach is to create one window context with specific window type and display and use it everywhere it's needed. After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, window context provides the capability to receive configuration changes for existing token by overriding the `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#token` of the `https://developer.android.com/reference/android/view/WindowManager.LayoutParams` passed in `https://developer.android.com/reference/android/view/ViewManager#addView(android.view.View,%20android.view.ViewGroup.LayoutParams)`. This is useful when an application needs to attach its window to an existing activity for window token sharing use-case. Note that the window context in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#R` didn't have this capability. This is a no-op for the window context in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#R`. Below is sample code to **attach an existing token to a window context:** ``` final DisplayManager dm = anyContext.getSystemService(DisplayManager.class); final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY); final Context windowContext = anyContext.createWindowContext(primaryDisplay, TYPE_APPLICATION, null); // Get an existing token. final IBinder existingToken = activity.getWindow().getAttributes().token; // The types used in addView() and createWindowContext() must match. final WindowManager.LayoutParams params = new WindowManager.LayoutParams(TYPE_APPLICATION); params.token = existingToken; // After WindowManager#addView(), the server side will extract the provided token from // LayoutParams#token (existingToken in the sample code), and switch to propagate // configuration changes from the node associated with the provided token. windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams); ``` After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, window context provides the capability to listen to its `https://developer.android.com/reference/android/content/res/Configuration` changes by calling `https://developer.android.com/reference/android/content/Context#registerComponentCallbacks(android.content.ComponentCallbacks)`, while other kinds of `https://developer.android.com/reference/android/content/Context` will register the `https://developer.android.com/reference/android/content/ComponentCallbacks` to `https://developer.android.com/reference/android/content/Context#getApplicationContext()`. Note that window context only propagate `https://developer.android.com/reference/android/content/ComponentCallbacks#onConfigurationChanged(android.content.res.Configuration)` callback. `https://developer.android.com/reference/android/content/ComponentCallbacks#onLowMemory()` or other callbacks in `https://developer.android.com/reference/android/content/ComponentCallbacks2` won't be invoked. Note that using `https://developer.android.com/reference/android/app/Application` or `https://developer.android.com/reference/android/app/Service` context for UI-related queries may result in layout or continuity issues on devices with variable screen sizes (e.g. foldables) or in multi-window modes, since these non-UI contexts may not reflect the `https://developer.android.com/reference/android/content/res/Configuration` changes for the visual container.

| Parameters || |---|---| | `type` | `int`: Value is one of the following: - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_BASE_APPLICATION` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_STARTING` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_DRAWN_APPLICATION` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_PANEL` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_MEDIA` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_SUB_PANEL` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_ATTACHED_DIALOG` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_STATUS_BAR` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_SEARCH_BAR` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_PHONE` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_SYSTEM_ALERT` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_TOAST` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_SYSTEM_OVERLAY` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_PRIORITY_PHONE` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_SYSTEM_DIALOG` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_KEYGUARD_DIALOG` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_SYSTEM_ERROR` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_INPUT_METHOD` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_INPUT_METHOD_DIALOG` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_WALLPAPER` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_PRIVATE_PRESENTATION` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_ACCESSIBILITY_OVERLAY` - `https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY` | | `options` | `Bundle`: This value may be `null`.

| ### enforceCallingOrSelfPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceCallingOrSelfPermission (String permission, String message) ``` If neither you nor the calling process of an IPC you are handling has been granted a particular permission, throw a `https://developer.android.com/reference/java/lang/SecurityException`. This is the same as `https://developer.android.com/reference/android/content/Context#enforceCallingPermission(java.lang.String,%20java.lang.String)`, except it grants your own permissions if you are not currently processing an IPC. Use with care!
| Parameters || |---|---| | `permission` | `String`: The name of the permission being checked. This value cannot be `null`.
| | `message` | `String`: This value may be `null`.
| ### enforceCallingOrSelfUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceCallingOrSelfUriPermission (Uri uri, int modeFlags, String message) ``` If the calling process of an IPC *or you* has not been granted permission to access a specific URI, throw `https://developer.android.com/reference/java/lang/SecurityException`. This is the same as `https://developer.android.com/reference/android/content/Context#enforceCallingUriPermission(android.net.Uri,%20int,%20java.lang.String)`, except it grants your own permissions if you are not currently processing an IPC. Use with care!
| Parameters || |---|---| | `uri` | `Uri`: The uri that is being checked.
| | `modeFlags` | `int`: The access modes to enforce. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` | | `message` | `String`: A message to include in the exception if it is thrown.
| ### enforceCallingPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceCallingPermission (String permission, String message) ``` If the calling process of an IPC you are handling has not been granted a particular permission, throw a `https://developer.android.com/reference/java/lang/SecurityException`. This is basically the same as calling `https://developer.android.com/reference/android/content/Context#enforcePermission(java.lang.String,%20int,%20int,%20java.lang.String)` with the pid and uid returned by `https://developer.android.com/reference/android/os/Binder#getCallingPid()` and `https://developer.android.com/reference/android/os/Binder#getCallingUid()`. One important difference is that if you are not currently processing an IPC, this function will always throw the SecurityException. This is done to protect against accidentally leaking permissions; you can use `https://developer.android.com/reference/android/content/Context#enforceCallingOrSelfPermission(java.lang.String,%20java.lang.String)` to avoid this protection.
| Parameters || |---|---| | `permission` | `String`: The name of the permission being checked. This value cannot be `null`.
| | `message` | `String`: This value may be `null`.
| ### enforceCallingUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceCallingUriPermission (Uri uri, int modeFlags, String message) ``` If the calling process and uid has not been granted permission to access a specific URI, throw `https://developer.android.com/reference/java/lang/SecurityException`. This is basically the same as calling `https://developer.android.com/reference/android/content/Context#enforceUriPermission(android.net.Uri,%20int,%20int,%20int,%20java.lang.String)` with the pid and uid returned by `https://developer.android.com/reference/android/os/Binder#getCallingPid()` and `https://developer.android.com/reference/android/os/Binder#getCallingUid()`. One important difference is that if you are not currently processing an IPC, this function will always throw a SecurityException.
| Parameters || |---|---| | `uri` | `Uri`: The uri that is being checked.
| | `modeFlags` | `int`: The access modes to enforce. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` | | `message` | `String`: A message to include in the exception if it is thrown.
| ### enforcePermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforcePermission (String permission, int pid, int uid, String message) ``` If the given permission is not allowed for a particular process and user ID running in the system, throw a `https://developer.android.com/reference/java/lang/SecurityException`.
| Parameters || |---|---| | `permission` | `String`: The name of the permission being checked. This value cannot be `null`.
| | `pid` | `int`: The process ID being checked against. Must be \> 0.
| | `uid` | `int`: The UID being checked against. A uid of 0 is the root user, which will pass every permission check.
| | `message` | `String`: This value may be `null`.
| ### enforceUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceUriPermission (Uri uri, String readPermission, String writePermission, int pid, int uid, int modeFlags, String message) ``` Enforce both a Uri and normal permission. This allows you to perform both `https://developer.android.com/reference/android/content/Context#enforcePermission(java.lang.String,%20int,%20int,%20java.lang.String)` and `https://developer.android.com/reference/android/content/Context#enforceUriPermission(android.net.Uri,%20int,%20int,%20int,%20java.lang.String)` in one call.
| Parameters || |---|---| | `uri` | `Uri`: This value may be `null`.
| | `readPermission` | `String`: This value may be `null`.
| | `writePermission` | `String`: This value may be `null`.
| | `pid` | `int`: The process ID being checked against. Must be \> 0.
| | `uid` | `int`: The UID being checked against. A uid of 0 is the root user, which will pass every permission check.

| ### enforceUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void enforceUriPermission (Uri uri, int pid, int uid, int modeFlags, String message) ``` If a particular process and uid has not been granted permission to access a specific URI, throw `https://developer.android.com/reference/java/lang/SecurityException`. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.
| Parameters || |---|---| | `uri` | `Uri`: The uri that is being checked.
| | `pid` | `int`: The process ID being checked against. Must be \> 0.
| | `uid` | `int`: The UID being checked against. A uid of 0 is the root user, which will pass every permission check.
| | `modeFlags` | `int`: The access modes to enforce. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` | | `message` | `String`: A message to include in the exception if it is thrown.
| ### fileList Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String[] fileList () ``` Returns an array of strings naming the private files associated with this Context's application package.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` | Array of strings naming the private files.
| ### getApplicationContext Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context getApplicationContext () ``` Return the context of the single, global Application object of the current process. This generally should only be used if you need a Context whose lifecycle is separate from the current context, that is tied to the lifetime of the process rather than the current component. Consider for example how this interacts with `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)`: - If used from an Activity context, the receiver is being registered within that activity. This means that you are expected to unregister before the activity is done being destroyed; in fact if you do not do so, the framework will clean up your leaked registration as it removes the activity and log an error. Thus, if you use the Activity context to register a receiver that is static (global to the process, not associated with an Activity instance) then that registration will be removed on you at whatever point the activity you used is destroyed. - If used from the Context returned here, the receiver is being registered with the global state associated with your application. Thus it will never be unregistered for you. This is necessary if the receiver is associated with static data, not a particular component. However using the ApplicationContext elsewhere can easily lead to serious leaks if you forget to unregister, unbind, etc.

| Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` |
| ### getApplicationInfo Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ApplicationInfo getApplicationInfo () ``` Return the full application info for this context's package.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/pm/ApplicationInfo` |
| ### getAssets Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public AssetManager getAssets () ``` Returns an AssetManager instance for the application's package. **Note:** Implementations of this method should return an AssetManager instance that is consistent with the Resources instance returned by `https://developer.android.com/reference/android/content/Context#getResources()`. For example, they should share the same `https://developer.android.com/reference/android/content/res/Configuration` object.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/res/AssetManager` | an AssetManager instance for the application's package
| ### getAttributionSource Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public AttributionSource getAttributionSource () ```

| Returns || |---|---| | `https://developer.android.com/reference/android/content/AttributionSource` | This value cannot be `null`.
| ### getAttributionTag Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getAttributionTag () ```
Attribution can be used in complex apps to logically separate parts of the app. E.g. a blogging app might also have a instant messaging app built in. In this case two separate tags can for used each sub-feature.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` | This value may be `null`.
| ### getBaseContext Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Context getBaseContext () ```

| Returns || |---|---| | `https://developer.android.com/reference/android/content/Context` | the base context as set by the constructor or setBaseContext
| ### getCacheDir Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getCacheDir () ``` Returns the absolute path to the application specific cache directory on the filesystem. The system will automatically delete files in this directory as disk space is needed elsewhere on the device. The system will always delete older files first, as reported by `https://developer.android.com/reference/java/io/File#lastModified()`. If desired, you can exert more control over how files are deleted using `https://developer.android.com/reference/android/os/storage/StorageManager#setCacheBehaviorGroup(java.io.File,%20boolean)` and `https://developer.android.com/reference/android/os/storage/StorageManager#setCacheBehaviorTombstone(java.io.File,%20boolean)`. Apps are strongly encouraged to keep their usage of cache space below the quota returned by `https://developer.android.com/reference/android/os/storage/StorageManager#getCacheQuotaBytes(java.util.UUID)`. If your app goes above this quota, your cached files will be some of the first to be deleted when additional disk space is needed. Conversely, if your app stays under this quota, your cached files will be some of the last to be deleted when additional disk space is needed. Note that your cache quota will change over time depending on how frequently the user interacts with your app, and depending on how much system-wide disk space is used. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | The path of the directory holding application cache files.
| ### getClassLoader Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ClassLoader getClassLoader () ``` Return a class loader you can use to retrieve classes in this package.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/ClassLoader` |
| ### getCodeCacheDir Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getCodeCacheDir () ``` Returns the absolute path to the application specific cache directory on the filesystem designed for storing cached code. The system will delete any files stored in this location both when your specific application is upgraded, and when the entire platform is upgraded. This location is optimal for storing compiled or optimized code generated by your application at runtime. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | The path of the directory holding application code cache files.
| ### getContentResolver Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ContentResolver getContentResolver () ``` Return a ContentResolver instance for your application's package.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/ContentResolver` |
| ### getDataDir Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getDataDir () ``` Returns the absolute path to the directory on the filesystem where all private files belonging to this app are stored. Apps should not use this path directly; they should instead use `https://developer.android.com/reference/android/content/Context#getFilesDir()`, `https://developer.android.com/reference/android/content/Context#getCacheDir()`, `https://developer.android.com/reference/android/content/Context#getDir(java.lang.String,%20int)`, or other storage APIs on this class. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. No additional permissions are required for the calling app to read or write files under the returned path.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` |
| ### getDatabasePath Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getDatabasePath (String name) ``` Returns the absolute path on the filesystem where a database created with `https://developer.android.com/reference/android/content/Context#openOrCreateDatabase(java.lang.String,%20int,%20android.database.sqlite.SQLiteDatabase.CursorFactory)` is stored. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.
| Parameters || |---|---| | `name` | `String`: The name of the database for which you would like to get its path.
| | Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | An absolute path to the given database.
| ### getDeviceId Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getDeviceId () ``` Gets the device ID this context is associated with. Applications can use this method to determine whether they are running on a virtual device and identify that device. The device ID of the host device is `https://developer.android.com/reference/android/content/Context#DEVICE_ID_DEFAULT` If the underlying device ID is changed by the system, for example, when an `https://developer.android.com/reference/android/app/Activity` is moved to a different virtual device, applications can register to listen to changes by calling `https://developer.android.com/reference/android/content/Context#registerDeviceIdChangeListener(java.util.concurrent.Executor,%20java.util.function.IntConsumer)`. This method will only return a reliable value for this instance if it was created with `https://developer.android.com/reference/android/content/Context#createDeviceContext(int)`, or if this instance is a UI or Display Context. Contexts created with `https://developer.android.com/reference/android/content/Context#createDeviceContext(int)` will have an explicit device association, which will never change, even if the underlying device is closed or is removed. UI Contexts and Display Contexts are already associated with a display, so if the device association is not explicitly given, `https://developer.android.com/reference/android/content/Context#getDeviceId()` will return the ID of the device associated with the associated display. The system can assign an arbitrary device id value for Contexts not logically associated with a device.

| Returns || |---|---| | `int` | the ID of the device this context is associated with.
| ### getDir Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getDir (String name, int mode) ``` Retrieve, creating if needed, a new directory in which the application can place its own custom data files. You can use the returned File object to create and access files in this directory. Note that files created through a File object will only be accessible by your own application; you can only set the mode of the entire directory, not of individual files. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. Apps require no extra permissions to read or write to the returned path, since this path lives in their private storage.
| Parameters || |---|---| | `name` | `String`: Name of the directory to retrieve. This is a directory that is created as part of your application data.
| | `mode` | `int`: Operating mode. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Context#MODE_PRIVATE` - `https://developer.android.com/reference/android/content/Context#MODE_WORLD_READABLE` - `https://developer.android.com/reference/android/content/Context#MODE_WORLD_WRITEABLE` - `https://developer.android.com/reference/android/content/Context#MODE_APPEND` | | Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | A `https://developer.android.com/reference/java/io/File` object for the requested directory. The directory will have been created if it does not already exist.
| ### getDisplay Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Display getDisplay () ``` Get the display this context is associated with. Applications should use this method with `https://developer.android.com/reference/android/app/Activity` or a context associated with a `https://developer.android.com/reference/android/view/Display` via `https://developer.android.com/reference/android/content/Context#createDisplayContext(android.view.Display)` to get a display object associated with a Context, or `https://developer.android.com/reference/android/hardware/display/DisplayManager#getDisplay(int)` to get a display object by id.
| Returns || |---|---| | `https://developer.android.com/reference/android/view/Display` | This value may be `null`.
| ### getExternalCacheDir Added in [API level 8](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getExternalCacheDir () ``` Returns absolute path to application-specific directory on the primary shared/external storage device where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media. This is like `https://developer.android.com/reference/android/content/Context#getCacheDir()` in that these files will be deleted when the application is uninstalled, however there are some important differences: - The platform does not always monitor the space available in shared storage, and thus may not automatically delete these files. Apps should always manage the maximum space used in this location. Currently the only time files here will be deleted by the platform is when running on `https://developer.android.com/reference/android/os/Build.VERSION_CODES#JELLY_BEAN_MR1` or later and `https://developer.android.com/reference/android/os/Environment#isExternalStorageEmulated(java.io.File)` returns true. - Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. If a shared storage device is emulated (as determined by `https://developer.android.com/reference/android/os/Environment#isExternalStorageEmulated(java.io.File)`), its contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directory returned by `https://developer.android.com/reference/android/content/Context#getCacheDir()`. Starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#KITKAT`, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` and/or `https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE` are required. On devices with multiple users (as described by `https://developer.android.com/reference/android/os/UserManager`), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as. The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | This value may be `null`.
| ### getExternalCacheDirs Added in [API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File[] getExternalCacheDirs () ``` Returns absolute paths to application-specific directories on all shared/external storage devices where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media. This is like `https://developer.android.com/reference/android/content/Context#getCacheDir()` in that these files will be deleted when the application is uninstalled, however there are some important differences: - The platform does not always monitor the space available in shared storage, and thus may not automatically delete these files.

Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. If a shared storage device is emulated (as determined by `https://developer.android.com/reference/android/os/Environment#isExternalStorageEmulated(java.io.File)`), its contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directory returned by `https://developer.android.com/reference/android/content/Context#getCacheDir()`. Shared storage devices returned here are considered a stable part of the device, including physical media slots under a protective cover. The returned paths do not include transient devices, such as USB flash drives connected to handheld devices. An application may store data on any or all of the returned devices. For example, an app may choose to store large files on the device with the most available space, as measured by `https://developer.android.com/reference/android/os/StatFs`. No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available. The returned paths may change over time if different shared storage media is inserted, so only relative paths should be persisted.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | the absolute paths to application-specific directories. Some individual paths may be `null` if that shared storage is not currently available. The first path returned is the same as `https://developer.android.com/reference/android/content/Context#getExternalCacheDir()`.
| ### getExternalFilesDir Added in [API level 8](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getExternalFilesDir (String type) ``` Returns the absolute path to the directory on the primary shared/external storage device where the application can place persistent files it owns. These files are internal to the applications, and not typically visible to the user as media. This is like `https://developer.android.com/reference/android/content/Context#getFilesDir()` in that these files will be deleted when the application is uninstalled, however there are some important differences: - Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. If a shared storage device is emulated (as determined by `https://developer.android.com/reference/android/os/Environment#isExternalStorageEmulated(java.io.File)`), its contents are backed by a private user data partition, which means there is little benefit to storing data here instead of the private directories returned by `https://developer.android.com/reference/android/content/Context#getFilesDir()`, etc. Starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#KITKAT`, no permissions are required to read or write to the returned path; it's always accessible to the calling app. This only applies to paths generated for package name of the calling application. To access paths belonging to other packages, `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` and/or `https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE` are required. On devices with multiple users (as described by `https://developer.android.com/reference/android/os/UserManager`), each user has their own isolated shared storage. Applications only have access to the shared storage for the user they're running as. The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted. Here is an example of typical code to manipulate a file in an application's shared storage: ``` void createExternalStoragePrivateFile() { // Create a path where we will place our private file on external // storage. File file = new File(getExternalFilesDir(null), "DemoFile.jpg"); try { // Very simple code to copy a picture from the application's // resource into the external file. Note that this code does // no error checking, and assumes the picture is small (does not // try to copy it in chunks). Note that if external storage is // not currently mounted this will silently fail. InputStream is = getResources().openRawResource(R.drawable.balloons); OutputStream os = new FileOutputStream(file); byte[] data = new byte[is.available()]; is.read(data); os.write(data); is.close(); os.close(); } catch (IOException e) { // Unable to create file, likely because external storage is // not currently mounted. Log.w("ExternalStorage", "Error writing " + file, e); } } void deleteExternalStoragePrivateFile() { // Get path for the file on external storage. If external // storage is not currently mounted this will fail. File file = new File(getExternalFilesDir(null), "DemoFile.jpg"); file.delete(); } boolean hasExternalStoragePrivateFile() { // Get path for the file on external storage. If external // storage is not currently mounted this will fail. File file = new File(getExternalFilesDir(null), "DemoFile.jpg"); return file.exists(); } ``` If you supply a non-null type to this function, the returned file will be a path to a sub-directory of the given type. Though these files are not automatically scanned by the media scanner, you can explicitly add them to the media database with `https://developer.android.com/reference/android/media/MediaScannerConnection#scanFile(android.content.Context,%20java.lang.String[],%20java.lang.String[],%20android.media.MediaScannerConnection.OnScanCompletedListener)`. Note that this is not the same as `https://developer.android.com/reference/android/os/Environment#getExternalStoragePublicDirectory(java.lang.String)`, which provides directories of media shared by all applications. The directories returned here are owned by the application, and their contents will be removed when the application is uninstalled. Unlike `https://developer.android.com/reference/android/os/Environment#getExternalStoragePublicDirectory(java.lang.String)`, the directory returned here will be automatically created for you. Here is an example of typical code to manipulate a picture in an application's shared storage and add it to the media database: ``` void createExternalStoragePrivatePicture() { // Create a path where we will place our picture in our own private // pictures directory. Note that we don't really need to place a // picture in DIRECTORY_PICTURES, since the media scanner will see // all media in these directories; this may be useful with other // media types such as DIRECTORY_MUSIC however to help it classify // your media for display to the user. File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES); File file = new File(path, "DemoPicture.jpg"); try { // Very simple code to copy a picture from the application's // resource into the external file. Note that this code does // no error checking, and assumes the picture is small (does not // try to copy it in chunks). Note that if external storage is // not currently mounted this will silently fail. InputStream is = getResources().openRawResource(R.drawable.balloons); OutputStream os = new FileOutputStream(file); byte[] data = new byte[is.available()]; is.read(data); os.write(data); is.close(); os.close(); // Tell the media scanner about the new file so that it is // immediately available to the user. MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null, new MediaScannerConnection.OnScanCompletedListener() { public void onScanCompleted(String path, Uri uri) { Log.i("ExternalStorage", "Scanned " + path + ":"); Log.i("ExternalStorage", "-> uri=" + uri); } }); } catch (IOException e) { // Unable to create file, likely because external storage is // not currently mounted. Log.w("ExternalStorage", "Error writing " + file, e); } } void deleteExternalStoragePrivatePicture() { // Create a path where we will place our picture in the user's // public pictures directory and delete the file. If external // storage is not currently mounted this will fail. File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES); if (path != null) { File file = new File(path, "DemoPicture.jpg"); file.delete(); } } boolean hasExternalStoragePrivatePicture() { // Create a path where we will place our picture in the user's // public pictures directory and check if the file exists.

File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES); if (path != null) { File file = new File(path, "DemoPicture.jpg"); return file.exists(); } return false; } ```

The returned path may change over time if different shared storage media is inserted, so only relative paths should be persisted.
| Parameters || |---|---| | `type` | `String`: The type of files directory to return. May be `null` for the root of the files directory or one of the following constants for a subdirectory: `https://developer.android.com/reference/android/os/Environment#DIRECTORY_MUSIC`, `https://developer.android.com/reference/android/os/Environment#DIRECTORY_PODCASTS`, `https://developer.android.com/reference/android/os/Environment#DIRECTORY_RINGTONES`, `https://developer.android.com/reference/android/os/Environment#DIRECTORY_ALARMS`, `https://developer.android.com/reference/android/os/Environment#DIRECTORY_NOTIFICATIONS`, `https://developer.android.com/reference/android/os/Environment#DIRECTORY_PICTURES`, or `https://developer.android.com/reference/android/os/Environment#DIRECTORY_MOVIES`.
| | Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | the absolute paths to application-specific directories. Some individual paths may be `null` if that shared storage is not currently available. The first path returned is the same as `https://developer.android.com/reference/android/content/Context#getExternalFilesDir(java.lang.String)`.
| ### getExternalMediaDirs Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File[] getExternalMediaDirs () ``` **This method is deprecated.** These directories still exist and are scanned, but developers are encouraged to migrate to inserting content into a `https://developer.android.com/reference/android/provider/MediaStore` collection directly, as any app can contribute new media to `https://developer.android.com/reference/android/provider/MediaStore` with no permissions required, starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#Q`. Returns absolute paths to application-specific directories on all shared/external storage devices where the application can place media files. These files are scanned and made available to other apps through `https://developer.android.com/reference/android/provider/MediaStore`. This is like `https://developer.android.com/reference/android/content/Context#getExternalFilesDirs(java.lang.String)` in that these files will be deleted when the application is uninstalled, however there are some important differences: - Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. Shared storage devices returned here are considered a stable part of the device, including physical media slots under a protective cover. The returned paths do not include transient devices, such as USB flash drives connected to handheld devices. An application may store data on any or all of the returned devices. For example, an app may choose to store large files on the device with the most available space, as measured by `https://developer.android.com/reference/android/os/StatFs`. No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available. The returned paths may change over time if different shared storage media is inserted, so only relative paths should be persisted.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | the absolute paths to application-specific directories. Some individual paths may be `null` if that shared storage is not currently available.
| ### getFileStreamPath Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getFileStreamPath (String name) ``` Returns the absolute path on the filesystem where a file created with `https://developer.android.com/reference/android/content/Context#openFileOutput(java.lang.String,%20int)` is stored. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.
| Parameters || |---|---| | `name` | `String`: The name of the file for which you would like to get its path.
| | Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | An absolute path to the given file.
| ### getFilesDir Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getFilesDir () ``` Returns the absolute path to the directory on the filesystem where files created with `https://developer.android.com/reference/android/content/Context#openFileOutput(java.lang.String,%20int)` are stored. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. No additional permissions are required for the calling app to read or write files under the returned path.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | The path of the directory holding application files.
| ### getMainExecutor Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Executor getMainExecutor () ``` Return an `https://developer.android.com/reference/java/util/concurrent/Executor` that will run enqueued tasks on the main thread associated with this context. This is the thread used to dispatch calls to application components (activities, services, etc).
| Returns || |---|---| | `https://developer.android.com/reference/java/util/concurrent/Executor` |
| ### getMainLooper Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Looper getMainLooper () ``` Return the Looper for the main thread of the current process. This is the thread used to dispatch calls to application components (activities, services, etc). By definition, this method returns the same result as would be obtained by calling `https://developer.android.com/reference/android/os/Looper#getMainLooper()`.

| Returns || |---|---| | `https://developer.android.com/reference/android/os/Looper` | The main looper.
| ### getNoBackupFilesDir Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getNoBackupFilesDir () ``` Returns the absolute path to the directory on the filesystem similar to `https://developer.android.com/reference/android/content/Context#getFilesDir()`. The difference is that files placed under this directory will be excluded from automatic backup to remote storage. See `https://developer.android.com/reference/android/app/backup/BackupAgent` for a full discussion of the automatic backup mechanism in Android. The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted. No additional permissions are required for the calling app to read or write files under the returned path.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | The path of the directory holding application files that will not be automatically backed up to remote storage.
| ### getObbDir Added in [API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File getObbDir () ``` Return the primary shared/external storage directory where this application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, this directory may not exist. This is like `https://developer.android.com/reference/android/content/Context#getFilesDir()` in that these files will be deleted when the application is uninstalled, however there are some important differences: - Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. Starting in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#KITKAT`, no permissions are required to read or write to the path that this method returns. However, starting from `https://developer.android.com/reference/android/os/Build.VERSION_CODES#M`, to read the OBB expansion files, you must declare the `https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE` permission in the app manifest and ask for permission at runtime as follows: `` Starting from `https://developer.android.com/reference/android/os/Build.VERSION_CODES#N`, `https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE` permission is not required, so don\\u2019t ask for this permission at runtime. To handle both cases, your app must first try to read the OBB file, and if it fails, you must request `https://developer.android.com/reference/android/Manifest.permission#READ_EXTERNAL_STORAGE` permission at runtime. The following code snippet shows how to do this: ``` File obb = new File(obb_filename); boolean open_failed = false; try { BufferedReader br = new BufferedReader(new FileReader(obb)); open_failed = false; ReadObbFile(br); } catch (IOException e) { open_failed = true; } if (open_failed) { // request READ_EXTERNAL_STORAGE permission before reading OBB file ReadObbFileWithPermission(); } ``` On devices with multiple users (as described by `https://developer.android.com/reference/android/os/UserManager`), multiple users may share the same OBB storage location. Applications should ensure that multiple instances running under different users don't interfere with each other.

| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | the absolute path to application-specific directory. May return `null` if shared storage is not currently available.
| ### getObbDirs Added in [API level 19](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public File[] getObbDirs () ``` Returns absolute paths to application-specific directories on all shared/external storage devices where the application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, these directories may not exist. This is like `https://developer.android.com/reference/android/content/Context#getFilesDir()` in that these files will be deleted when the application is uninstalled, however there are some important differences: - Shared storage may not always be available, since removable media can be ejected by the user. Media state can be checked using `https://developer.android.com/reference/android/os/Environment#getExternalStorageState(java.io.File)`. - There is no security enforced with these files. For example, any application holding `https://developer.android.com/reference/android/Manifest.permission#WRITE_EXTERNAL_STORAGE` can write to these files. Shared storage devices returned here are considered a stable part of the device, including physical media slots under a protective cover. The returned paths do not include transient devices, such as USB flash drives connected to handheld devices. An application may store data on any or all of the returned devices. For example, an app may choose to store large files on the device with the most available space, as measured by `https://developer.android.com/reference/android/os/StatFs`. No additional permissions are required for the calling app to read or write files under the returned path. Write access outside of these paths on secondary external storage devices is not available.
| Returns || |---|---| | `https://developer.android.com/reference/java/io/File` | the absolute paths to application-specific directories. Some individual paths may be `null` if that shared storage is not currently available. The first path returned is the same as `https://developer.android.com/reference/android/content/Context#getObbDir()`
| ### getOpPackageName Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getOpPackageName () ``` Return the package name that should be used for `https://developer.android.com/reference/android/app/AppOpsManager` calls from this context, so that app ops manager's uid verification will work with the name. This is not generally intended for third party application developers.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` | This value cannot be `null`.
| ### getPackageCodePath Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getPackageCodePath () ``` Return the full path to this context's primary Android package. The Android package is a ZIP file which contains application's primary code and assets. Note: this is not generally useful for applications, since they should not be directly accessing the file system.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` | String Path to the code and assets.
| ### getPackageManager Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public PackageManager getPackageManager () ``` Return PackageManager instance to find global package information.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/pm/PackageManager` |
| ### getPackageName Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getPackageName () ``` Return the name of this application's package.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` |
| ### getPackageResourcePath Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public String getPackageResourcePath () ``` Return the full path to this context's primary Android package. The Android package is a ZIP file which contains the application's primary resources. Note: this is not generally useful for applications, since they should not be directly accessing the file system.
| Returns || |---|---| | `https://developer.android.com/reference/java/lang/String` | String Path to the resources.
| ### getParams Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ContextParams getParams () ``` Return the set of parameters which this Context was created with, if it was created via `https://developer.android.com/reference/android/content/Context#createContext(android.content.ContextParams)`.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/ContextParams` | This value may be `null`.
| ### getResources Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Resources getResources () ``` Returns a Resources instance for the application's package. **Note:** Implementations of this method should return a Resources instance that is consistent with the AssetManager instance returned by `https://developer.android.com/reference/android/content/Context#getAssets()`. For example, they should share the same `https://developer.android.com/reference/android/content/res/Configuration` object.
| Returns || |---|---| | `https://developer.android.com/reference/android/content/res/Resources` | a Resources instance for the application's package
| ### getSharedPreferences Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public SharedPreferences getSharedPreferences (String name, int mode) ``` Retrieve and hold the contents of the preferences file 'name', returning a SharedPreferences through which you can retrieve and modify its values. Only one instance of the SharedPreferences object is returned to any callers for the same name, meaning they will see each other's edits as soon as they are made. This method is thread-safe. If the preferences directory does not already exist, it will be created when this method is called. If a preferences file by this name does not exist, it will be created when you retrieve an editor (`https://developer.android.com/reference/android/content/SharedPreferences#edit()`) and then commit changes (`https://developer.android.com/reference/android/content/SharedPreferences.Editor#commit()` or `https://developer.android.com/reference/android/content/SharedPreferences.Editor#apply()`).
| Parameters || |---|---| | `name` | `String`: Desired preferences file.
| | `mode` | `int`: Operating mode. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Context#MODE_PRIVATE` - `https://developer.android.com/reference/android/content/Context#MODE_WORLD_READABLE` - `https://developer.android.com/reference/android/content/Context#MODE_WORLD_WRITEABLE` - `https://developer.android.com/reference/android/content/Context#MODE_MULTI_PROCESS` | | Returns || |---|---| | `https://developer.android.com/reference/android/content/SharedPreferences` | The single `https://developer.android.com/reference/android/content/SharedPreferences` instance that can be used to retrieve and modify the preference values.
| ### getSystemService Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Object getSystemService (String name) ``` Return the handle to a system-level service by name. The class of the returned object varies by the requested name. Currently available names are: `https://developer.android.com/reference/android/content/Context#WINDOW_SERVICE` ("window") : The top-level window manager in which you can place custom windows. The returned object is a `https://developer.android.com/reference/android/view/WindowManager`.

Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.) Note: Instant apps, for which `https://developer.android.com/reference/android/content/pm/PackageManager#isInstantApp()` returns true, don't have access to the following system services: `https://developer.android.com/reference/android/content/Context#DEVICE_POLICY_SERVICE`, `https://developer.android.com/`, `https://developer.android.com/reference/android/content/Context#KEYGUARD_SERVICE`, `https://developer.android.com/reference/android/content/Context#SHORTCUT_SERVICE`, `https://developer.android.com/reference/android/content/Context#USB_SERVICE`, `https://developer.android.com/reference/android/content/Context#WALLPAPER_SERVICE`, `https://developer.android.com/reference/android/content/Context#WIFI_P2P_SERVICE`, `https://developer.android.com/reference/android/content/Context#WIFI_SERVICE`, `https://developer.android.com/reference/android/content/Context#WIFI_AWARE_SERVICE`. For these services this method will return `null`. Generally, if you are running as an instant app you should always check whether the result of this method is `null`. Note: When implementing this method, keep in mind that new services can be added on newer Android releases, so if you're looking for just the explicit names mentioned above, make sure to return `null` when you don't recognize the name --- if you throw a `https://developer.android.com/reference/java/lang/RuntimeException` exception instead, your app might break on new Android releases.

| Returns || |---|---| | `int` |
| ### grantUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void grantUriPermission (String toPackage, Uri uri, int modeFlags) ``` Grant permission to access a specific Uri to another package, regardless of whether that package has general permission to access the Uri's content provider. This can be used to grant specific, temporary permissions, typically in response to user interaction (such as the user opening an attachment that you would like someone else to display). Normally you should use `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` or `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call `https://developer.android.com/reference/android/content/Context#revokeUriPermission(android.net.Uri,%20int)` when the target should no longer be allowed to access it. To succeed, the content provider owning the Uri must have set the `https://developer.android.com/reference/android/R.styleable#AndroidManifestProvider_grantUriPermissions` attribute in its manifest or included the `https://developer.android.com/reference/android/R.styleable#AndroidManifestGrantUriPermission` tag.
| Parameters || |---|---| | `toPackage` | `String`: The package you would like to allow to access the Uri.
| | `uri` | `Uri`: The Uri you would like to grant access to.
| | `modeFlags` | `int`: The desired access modes.

Accessing UI components from non-UI contexts throws `https://developer.android.com/reference/android/os/strictmode/Violation` if `https://developer.android.com/reference/android/os/StrictMode.VmPolicy.Builder#detectIncorrectContextUse()` is enabled. Examples of UI contexts are an `https://developer.android.com/reference/android/app/Activity`, a context created from `https://developer.android.com/reference/android/content/Context#createWindowContext(int,%20android.os.Bundle)` or `https://developer.android.com/reference/android/inputmethodservice/InputMethodService` Note that even if it is allowed programmatically, it is not suggested to override this method to bypass `https://developer.android.com/reference/android/os/strictmode/IncorrectContextUseViolation` verification.

Users can still call to `getApplicationContext().registerComponentCallbacks(ComponentCallbacks)` to add `https://developer.android.com/reference/android/content/ComponentCallbacks` to the base application.
| Parameters || |---|---| | `callback` | `ComponentCallbacks`: The interface to call. This can be either a `https://developer.android.com/reference/android/content/ComponentCallbacks` or `https://developer.android.com/reference/android/content/ComponentCallbacks2` interface.
| | Throws || |---|---| | `https://developer.android.com/reference/java/lang/IllegalStateException` | if this method calls before `https://developer.android.com/reference/android/content/ContextWrapper#attachBaseContext(android.content.Context)` | ### registerDeviceIdChangeListener Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void registerDeviceIdChangeListener (Executor executor, IntConsumer listener) ``` Adds a new device ID changed listener to the `Context`, which will be called when the device association is changed by the system. The callback can be called when an app is moved to a different device and the `Context` is not explicitly associated with a specific device. When an application receives a device id update callback, this Context is guaranteed to also have an updated display ID(if any) and `https://developer.android.com/reference/android/content/res/Configuration`.


| Parameters || |---|---| | `executor` | `Executor`: This value cannot be `null`. Callback and listener events are dispatched through this `https://developer.android.com/reference/java/util/concurrent/Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `https://developer.android.com/reference/android/content/Context#getMainExecutor()`. Otherwise, provide an `https://developer.android.com/reference/java/util/concurrent/Executor` that dispatches to an appropriate thread.
| | `listener` | `IntConsumer`: This value cannot be `null`.
| ### registerReceiver Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Intent registerReceiver (BroadcastReceiver receiver, IntentFilter filter) ``` Register a BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread. The system may broadcast Intents that are "sticky" -- these stay around after the broadcast has finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function **and** sent to your receiver as if it had just been broadcast. There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system. If you know the Intent you are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply. See `https://developer.android.com/reference/android/content/BroadcastReceiver` for more information on Intent broadcasts. As of `https://developer.android.com/reference/android/os/Build.VERSION_CODES#UPSIDE_DOWN_CAKE`, the system can [place context-registered broadcasts in a queue while the app is in the](https://developer.android.com/develop/background-work/background-tasks/broadcasts#android-14)[cached state](https://developer.android.com/guide/components/activities/process-lifecycle). When the app leaves the cached state, such as returning to the foreground, the system delivers any queued broadcasts. Multiple instances of certain broadcasts might be merged into one broadcast. As of `https://developer.android.com/reference/android/os/Build.VERSION_CODES#ICE_CREAM_SANDWICH`, receivers registered with this method will correctly respect the `https://developer.android.com/reference/android/content/Intent#setPackage(java.lang.String)` specified for an Intent being broadcast. Prior to that, it would be ignored and delivered to all matching registered receivers. Be careful if using this for security. For apps targeting `https://developer.android.com/reference/android/os/Build.VERSION_CODES#UPSIDE_DOWN_CAKE`, either `https://developer.android.com/reference/android/content/Context#RECEIVER_EXPORTED` or `https://developer.android.com/reference/android/content/Context#RECEIVER_NOT_EXPORTED` must be specified if the receiver is not being registered for [system broadcasts](https://developer.android.com/guide/components/broadcasts#system-broadcasts) or a `https://developer.android.com/reference/java/lang/SecurityException` will be thrown. See `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter,%20int)` to register a receiver with flags. Note: this method *cannot be called from a `https://developer.android.com/reference/android/content/BroadcastReceiver` component;* that is, from a BroadcastReceiver that is declared in an application's manifest. It is okay, however, to call this method from another BroadcastReceiver that has itself been registered at run time with `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)`, since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.

| Parameters || |---|---| | `receiver` | `BroadcastReceiver`: This value may be `null`.
| | `filter` | `IntentFilter`: Selects the Intent broadcasts to be received.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/Intent` | The first sticky intent found that matches filter, or null if there are none.
| ### registerReceiver Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Intent registerReceiver (BroadcastReceiver receiver, IntentFilter filter, int flags) ``` Register to receive intent broadcasts, with the receiver optionally being exposed to Instant Apps. See `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)` for more information.

| ### registerReceiver Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Intent registerReceiver (BroadcastReceiver receiver, IntentFilter filter, String broadcastPermission, Handler scheduler) ``` Register to receive intent broadcasts, to run in the context of scheduler. See `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)` for more information. This allows you to enforce permissions on who can broadcast intents to your receiver, or have the receiver run in a different thread than the main application thread. See `https://developer.android.com/reference/android/content/BroadcastReceiver` for more information on Intent broadcasts. As of `https://developer.android.com/reference/android/os/Build.VERSION_CODES#UPSIDE_DOWN_CAKE`, the system can [place context-registered broadcasts in a queue while the app is in the](https://developer.android.com/develop/background-work/background-tasks/broadcasts#android-14)[cached state](https://developer.android.com/guide/components/activities/process-lifecycle).

| ### removeStickyBroadcast Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void removeStickyBroadcast (Intent intent) ``` **This method is deprecated.** Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that *something* has changed, with another mechanism for apps to retrieve the current value whenever desired.
Remove the data previously sent with `https://developer.android.com/reference/android/content/Context#sendStickyBroadcast(android.content.Intent)`, so that it is as if the sticky broadcast had never happened. Requires `https://developer.android.com/reference/android/Manifest.permission#BROADCAST_STICKY`
| Parameters || |---|---| | `intent` | `Intent`: The Intent that was previously broadcast.
| ### removeStickyBroadcastAsUser Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void removeStickyBroadcastAsUser (Intent intent, UserHandle user) ``` **This method is deprecated.** Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that *something* has changed, with another mechanism for apps to retrieve the current value whenever desired.
Version of `https://developer.android.com/reference/android/content/Context#removeStickyBroadcast(android.content.Intent)` that allows you to specify the user the broadcast will be sent to. This is not available to applications that are not pre-installed on the system image. You must hold the `https://developer.android.com/reference/android/Manifest.permission#BROADCAST_STICKY` permission in order to use this API. If you do not hold that permission, `https://developer.android.com/reference/java/lang/SecurityException` will be thrown. Requires android.Manifest.permission.INTERACT_ACROSS_USERS and `https://developer.android.com/reference/android/Manifest.permission#BROADCAST_STICKY`
| Parameters || |---|---| | `intent` | `Intent`: The Intent that was previously broadcast.
| | `user` | `UserHandle`: UserHandle to remove the sticky broadcast from.
| ### revokeSelfPermissionsOnKill Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void revokeSelfPermissionsOnKill (Collection permissions) ``` Triggers the revocation of one or more permissions for the calling package. A package is only able to revoke runtime permissions. If a permission is not currently granted, it is ignored and will not get revoked (even if later granted by the user). Ultimately, you should never make assumptions about a permission status as users may grant or revoke them at any time. Background permissions which have no corresponding foreground permission still granted once the revocation is effective will also be revoked. The revocation happens asynchronously and kills all processes running in the calling UID. It will be triggered once it is safe to do so. In particular, it will not be triggered as long as the package remains in the foreground, or has any active manifest components (e.g. when another app is accessing a content provider in the package). If you want to revoke the permissions right away, you could call `System.exit()` in `Handler.postDelayed` with a delay to allow completion of async IPC, But `System.exit()` could affect other apps that are accessing your app at the moment. For example, apps accessing a content provider in your app will all crash. Note that the settings UI shows a permission group as granted as long as at least one permission in the group is granted. If you want the user to observe the revocation in the settings, you should revoke every permission in the target group. To learn the current list of permissions in a group, you may use `https://developer.android.com/reference/android/content/pm/PackageManager#getGroupOfPlatformPermission(java.lang.String,%20java.util.concurrent.Executor,%20java.util.function.Consumer)` and `https://developer.android.com/reference/android/content/pm/PackageManager#getPlatformPermissionsForGroup(java.lang.String,%20java.util.concurrent.Executor,%20java.util.function.Consumer>)`. This list of permissions may evolve over time, so it is recommended to check whether it contains any permission you wish to retain before trying to revoke an entire group.
| Parameters || |---|---| | `permissions` | `Collection`: This value cannot be `null`.
| ### revokeUriPermission Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void revokeUriPermission (Uri uri, int modeFlags) ``` Remove all permissions to access a particular content provider Uri that were previously added with `https://developer.android.com/reference/android/content/Context#grantUriPermission(java.lang.String,%20android.net.Uri,%20int)` or *any other* mechanism. The given Uri will match all previously granted Uris that are the same or a sub-path of the given Uri. That is, revoking "content://foo/target" will revoke both "content://foo/target" and "content://foo/target/sub", but not "content://foo". It will not remove any prefix grants that exist at a higher level. Prior to `https://developer.android.com/reference/android/os/Build.VERSION_CODES#LOLLIPOP`, if you did not have regular permission access to a Uri, but had received access to it through a specific Uri permission grant, you could not revoke that grant with this function and a `https://developer.android.com/reference/java/lang/SecurityException` would be thrown. As of `https://developer.android.com/reference/android/os/Build.VERSION_CODES#LOLLIPOP`, this function will not throw a security exception, but will remove whatever permission grants to the Uri had been given to the app (or none). Unlike `https://developer.android.com/reference/android/content/Context#revokeUriPermission(java.lang.String,%20android.net.Uri,%20int)`, this method impacts all permission grants matching the given Uri, for any package they had been granted to, through any mechanism this had happened (such as indirectly through the clipboard, activity launch, service start, etc). That means this can be potentially dangerous to use, as it can revoke grants that another app could be strongly expecting to stick around.

| Parameters || |---|---| | `uri` | `Uri`: The Uri you would like to revoke access to.
| | `modeFlags` | `int`: The access modes to revoke. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` | ### revokeUriPermission Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void revokeUriPermission (String targetPackage, Uri uri, int modeFlags) ``` Remove permissions to access a particular content provider Uri that were previously added with `https://developer.android.com/reference/android/content/Context#grantUriPermission(java.lang.String,%20android.net.Uri,%20int)` for a specific target package. The given Uri will match all previously granted Uris that are the same or a sub-path of the given Uri. That is, revoking "content://foo/target" will revoke both "content://foo/target" and "content://foo/target/sub", but not "content://foo". It will not remove any prefix grants that exist at a higher level. Unlike `https://developer.android.com/reference/android/content/Context#revokeUriPermission(android.net.Uri,%20int)`, this method will *only* revoke permissions that had been explicitly granted through `https://developer.android.com/reference/android/content/Context#grantUriPermission(java.lang.String,%20android.net.Uri,%20int)` and only for the package specified. Any matching grants that have happened through other mechanisms (clipboard, activity launching, service starting, etc) will not be removed.

| Parameters || |---|---| | `targetPackage` | `String`: The package you had previously granted access to.
| | `uri` | `Uri`: The Uri you would like to revoke access to.
| | `modeFlags` | `int`: The access modes to revoke. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_READ_URI_PERMISSION` - `https://developer.android.com/reference/android/content/Intent#FLAG_GRANT_WRITE_URI_PERMISSION` | ### sendBroadcast Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void sendBroadcast (Intent intent, String receiverPermission, Bundle options) ``` Broadcast the given intent to all interested BroadcastReceivers, allowing an optional required permission to be enforced. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run. No results are propagated from receivers and receivers can not abort the broadcast.

This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its `https://developer.android.com/reference/android/content/BroadcastReceiver#onReceive(android.content.Context,%20android.content.Intent)` method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling `https://developer.android.com/reference/android/content/Context#sendOrderedBroadcast(android.content.Intent,%20java.lang.String)`. Like `https://developer.android.com/reference/android/content/Context#sendBroadcast(android.content.Intent)`, this method is asynchronous; it will return before resultReceiver.onReceive() is called. See `https://developer.android.com/reference/android/content/BroadcastReceiver` for more information on Intent broadcasts.
| Parameters || |---|---| | `intent` | `Intent`: The Intent to broadcast; all receivers matching this Intent will receive the broadcast. This value cannot be `null`.
| | `receiverPermission` | `String`: This value may be `null`.
| | `resultReceiver` | `BroadcastReceiver`: This value may be `null`.
| | `scheduler` | `Handler`: This value may be `null`.
| | `initialCode` | `int`: An initial value for the result code. Often Activity.RESULT_OK.

| ### sendStickyBroadcast Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void sendStickyBroadcast (Intent intent) ``` **This method is deprecated.** Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that *something* has changed, with another mechanism for apps to retrieve the current value whenever desired.
Perform a `https://developer.android.com/reference/android/content/Context#sendBroadcast(android.content.Intent)` that is "sticky," meaning the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of `https://developer.android.com/reference/android/content/Context#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)`. In all other ways, this behaves the same as `https://developer.android.com/reference/android/content/Context#sendBroadcast(android.content.Intent)`. Requires `https://developer.android.com/reference/android/Manifest.permission#BROADCAST_STICKY`
| Parameters || |---|---| | `intent` | `Intent`: The Intent to broadcast; all receivers matching this Intent will receive the broadcast, and the Intent will be held to be re-broadcast to future receivers.

They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that *something* has changed, with another mechanism for apps to retrieve the current value whenever desired.
Perform a `https://developer.android.com/reference/android/content/ContextWrapper#sendBroadcast(android.content.Intent)` that is "sticky," meaning the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of `https://developer.android.com/reference/android/content/ContextWrapper#registerReceiver(android.content.BroadcastReceiver,%20android.content.IntentFilter)`. In all other ways, this behaves the same as `https://developer.android.com/reference/android/content/ContextWrapper#sendBroadcast(android.content.Intent)`.
| Parameters || |---|---| | `intent` | `Intent`: The Intent to broadcast; all receivers matching this Intent will receive the broadcast, and the Intent will be held to be re-broadcast to future receivers. This value cannot be `null`.
| | `options` | `Bundle`: (optional) Additional sending options, generated from a `https://developer.android.com/reference/android/app/BroadcastOptions`. This value may be `null`.

Version of `https://developer.android.com/reference/android/content/Context#sendStickyBroadcast(android.content.Intent)` that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its `https://developer.android.com/reference/android/content/BroadcastReceiver#onReceive(android.content.Context,%20android.content.Intent)` method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling `https://developer.android.com/reference/android/content/Context#sendOrderedBroadcast(android.content.Intent,%20java.lang.String)`. Like `https://developer.android.com/reference/android/content/Context#sendBroadcast(android.content.Intent)`, this method is asynchronous; it will return before resultReceiver.onReceive() is called. Note that the sticky data stored is only the data you initially supply to the broadcast, not the result of any changes made by the receivers. See `https://developer.android.com/reference/android/content/BroadcastReceiver` for more information on Intent broadcasts. Requires `https://developer.android.com/reference/android/Manifest.permission#BROADCAST_STICKY`

| ### setTheme Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setTheme (int resid) ``` Set the base theme for this context. Note that this should be called before any views are instantiated in the Context (for example before calling `https://developer.android.com/reference/android/app/Activity#setContentView(android.view.View)` or `https://developer.android.com/reference/android/view/LayoutInflater#inflate(int,%20android.view.ViewGroup)`).
| Parameters || |---|---| | `resid` | `int`: The style resource describing the theme.
| ### setWallpaper Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setWallpaper (Bitmap bitmap) ``` **This method is deprecated.** Use `https://developer.android.com/reference/android/app/WallpaperManager#setBitmap(android.graphics.Bitmap)` instead. This method requires the caller to hold the permission `https://developer.android.com/reference/android/Manifest.permission#SET_WALLPAPER`.

| Parameters || |---|---| | `bitmap` | `Bitmap`
| | Throws || |---|---| | `https://developer.android.com/reference/java/io/IOException` | | ### setWallpaper Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void setWallpaper (InputStream data) ``` **This method is deprecated.** Use `https://developer.android.com/reference/android/app/WallpaperManager#setStream(java.io.InputStream)` instead. This method requires the caller to hold the permission `https://developer.android.com/reference/android/Manifest.permission#SET_WALLPAPER`.

| Parameters || |---|---| | `data` | `InputStream`
| | Throws || |---|---| | `https://developer.android.com/reference/java/io/IOException` | | ### shouldShowRequestPermissionRationale Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions) ``` public boolean shouldShowRequestPermissionRationale (String permission) ``` Gets whether you should show UI with rationale before requesting a permission. If the permission does not exist on this SDK level or is not visible to this app, the method will return `false`.
| Parameters || |---|---| | `permission` | `String`: This value cannot be `null`.
| | Returns || |---|---| | `boolean` | Whether you should show permission rationale UI.
| ### startActivities Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void startActivities (Intent[] intents, Bundle options) ``` Launch multiple new activities. This is generally the same as calling `https://developer.android.com/reference/android/content/Context#startActivity(android.content.Intent)` for the first Intent in the array, that activity during its creation calling `https://developer.android.com/reference/android/content/Context#startActivity(android.content.Intent)` for the second entry, etc. Note that unlike that approach, generally none of the activities except the last in the array will be created at this point, but rather will be created when the user first visits them (due to pressing back from the activity on top). This method throws `https://developer.android.com/reference/android/content/ActivityNotFoundException` if there was no Activity found for *any* given Intent. In this case the state of the activity stack is undefined (some Intents in the list may be on it, some not), so you probably want to avoid such situations.
| Parameters || |---|---| | `intents` | `Intent`: An array of Intents to be started.
| | `options` | `Bundle`: This value may be `null`.
| ### startActivities Added in [API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void startActivities (Intent[] intents) ``` Same as `https://developer.android.com/reference/android/content/Context#startActivities(android.content.Intent[],%20android.os.Bundle)` with no options specified.
| Parameters || |---|---| | `intents` | `Intent`: An array of Intents to be started.
| ### startActivity Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void startActivity (Intent intent) ``` Same as `https://developer.android.com/reference/android/content/Context#startActivity(android.content.Intent,%20android.os.Bundle)` with no options specified.
| Parameters || |---|---| | `intent` | `Intent`: The description of the activity to start.
| ### startActivity Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void startActivity (Intent intent, Bundle options) ``` Launch a new activity. You will not receive any information about when the activity exits. Note that if this method is being called from outside of an `https://developer.android.com/reference/android/app/Activity` Context, then the Intent must include the `https://developer.android.com/reference/android/content/Intent#FLAG_ACTIVITY_NEW_TASK` launch flag. This is because, without being started from an existing Activity, there is no existing task in which to place the new activity and thus it needs to be placed in its own separate task. This method throws `https://developer.android.com/reference/android/content/ActivityNotFoundException` if there was no Activity found to run the given Intent.
| Parameters || |---|---| | `intent` | `Intent`: The description of the activity to start.
| | `options` | `Bundle`: This value may be `null`.
| ### startForegroundService Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ComponentName startForegroundService (Intent service) ``` Similar to `https://developer.android.com/reference/android/content/Context#startService(android.content.Intent)`, but with an implicit promise that the Service will call `https://developer.android.com/reference/android/app/Service#startForeground(int,%20android.app.Notification)` once it begins running. The service is given an amount of time comparable to the ANR interval to do this, otherwise the system will automatically crash the process, in which case an internal exception `ForegroundServiceDidNotStartInTimeException` is logged on logcat on devices running SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S` or later. On older Android versions, an internal exception `RemoteServiceException` is logged instead, with a corresponding message. Unlike the ordinary `https://developer.android.com/reference/android/content/Context#startService(android.content.Intent)`, this method can be used at any time, regardless of whether the app hosting the service is in a foreground state. **Note:** Beginning with SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, apps targeting SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S` or higher are not allowed to start foreground services from the background. See [Behavior changes: Apps targeting Android 12](https://developer.android.com/about/versions/12/behavior-changes-12) for more details.

| Parameters || |---|---| | `service` | `Intent`: Identifies the service to be started. The Intent must be fully explicit (supplying a component name). Additional values may be included in the Intent extras to supply arguments along with this specific start call.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/ComponentName` | This value may be `null`.
| ### startInstrumentation Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean startInstrumentation (ComponentName className, String profileFile, Bundle arguments) ``` Start executing an `https://developer.android.com/reference/android/app/Instrumentation` class. The given Instrumentation component will be run by killing its target application (if currently running), starting the target process, instantiating the instrumentation component, and then letting it drive the application. This function is not synchronous -- it returns as soon as the instrumentation has started and while it is running. Instrumentation is normally only allowed to run against a package that is either unsigned or signed with a signature that the the instrumentation package is also signed with (ensuring the target trusts the instrumentation).
| Parameters || |---|---| | `className` | `ComponentName`: Name of the Instrumentation component to be run. This value cannot be `null`.
| | `profileFile` | `String`: This value may be `null`.
| | `arguments` | `Bundle`: This value may be `null`.
| | Returns || |---|---| | `boolean` | `true` if the instrumentation was successfully started, else `false` if it could not be found.
| ### startIntentSender Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void startIntentSender (IntentSender intent, Intent fillInIntent, int flagsMask, int flagsValues, int extraFlags) ``` Same as `https://developer.android.com/reference/android/content/Context#startIntentSender(android.content.IntentSender,%20android.content.Intent,%20int,%20int,%20int,%20android.os.Bundle)` with no options specified.
| Parameters || |---|---| | `intent` | `IntentSender`: The IntentSender to launch.
| | `fillInIntent` | `Intent`: This value may be `null`.

| | Throws || |---|---| | `https://developer.android.com/reference/android/content/IntentSender.SendIntentException` | | ### startService Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public ComponentName startService (Intent service) ``` Request that a given application service be started. The Intent should either contain the complete class name of a specific service implementation to start, or a specific package name to target. If the Intent is less specified, it logs a warning about this. In this case any of the multiple matching services may be used. If this service is not already running, it will be instantiated and started (creating a process for it if needed); if it is running then it remains running. Every call to this method will result in a corresponding call to the target service's `https://developer.android.com/reference/android/app/Service#onStartCommand(android.content.Intent,%20int,%20int)` method, with the intent given here. This provides a convenient way to submit jobs to a service without having to bind and call on to its interface. Using startService() overrides the default service lifetime that is managed by `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)`: it requires the service to remain running until `https://developer.android.com/reference/android/content/Context#stopService(android.content.Intent)` is called, regardless of whether any clients are connected to it. Note that calls to startService() do not nest: no matter how many times you call startService(), a single call to `https://developer.android.com/reference/android/content/Context#stopService(android.content.Intent)` will stop it. The system attempts to keep running services around as much as possible. The only time they should be stopped is if the current foreground application is using so many resources that the service needs to be killed. If any errors happen in the service's process, it will automatically be restarted. This function will throw `https://developer.android.com/reference/java/lang/SecurityException` if you do not have permission to start the given service. **Note:** Each call to startService() results in significant work done by the system to manage service lifecycle surrounding the processing of the intent, which can take multiple milliseconds of CPU time. Due to this cost, startService() should not be used for frequent intent delivery to a service, and only for scheduling significant work. Use `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` for high frequency calls. Beginning with SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#O`, apps targeting SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#O` or higher are not allowed to start background services from the background. See [Background Execution Limits](https://developer.android.com/about/versions/oreo/background) for more details. **Note:** Beginning with SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, apps targeting SDK Version `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S` or higher are not allowed to start foreground services from the background. See [Behavior changes: Apps targeting Android 12](https://developer.android.com/about/versions/12/behavior-changes-12) for more details.

| Parameters || |---|---| | `service` | `Intent`: Identifies the service to be started. The Intent must be fully explicit (supplying a component name). Additional values may be included in the Intent extras to supply arguments along with this specific start call.
| | Returns || |---|---| | `https://developer.android.com/reference/android/content/ComponentName` | This value may be `null`.
| ### stopService Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public boolean stopService (Intent name) ``` Request that a given application service be stopped. If the service is not running, nothing happens. Otherwise it is stopped. Note that calls to startService() are not counted -- this stops the service no matter how many times it was started. If the service is running as a foreground service when it is stopped, its associated notification will be removed. To avoid this, apps can use `https://developer.android.com/reference/android/app/Service#stopForeground(int)` to decouple the notification from the service's lifecycle before stopping it. Note that if a stopped service still has `https://developer.android.com/reference/android/content/ServiceConnection` objects bound to it with the `https://developer.android.com/reference/android/content/Context#BIND_AUTO_CREATE` set, it will not be destroyed until all of these bindings are removed. See the `https://developer.android.com/reference/android/app/Service` documentation for more details on a service's lifecycle. This function will throw `https://developer.android.com/reference/java/lang/SecurityException` if you do not have permission to stop the given service.
| Parameters || |---|---| | `name` | `Intent`: Description of the service to be stopped. The Intent must be either fully explicit (supplying a component name) or specify a specific package name it is targeted to.
| | Returns || |---|---| | `boolean` | If there is a service matching the given Intent that is already running, then it is stopped and `true` is returned; else `false` is returned.
| ### unbindService Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void unbindService (ServiceConnection conn) ``` Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time.
| Parameters || |---|---| | `conn` | `ServiceConnection`: The connection interface previously supplied to bindService(). This parameter must not be null.
| ### unregisterComponentCallbacks Added in [API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void unregisterComponentCallbacks (ComponentCallbacks callback) ``` Remove a `https://developer.android.com/reference/android/content/ComponentCallbacks` object that was previously registered with `https://developer.android.com/reference/android/content/ContextWrapper#registerComponentCallbacks(android.content.ComponentCallbacks)`. After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#TIRAMISU`, the `https://developer.android.com/reference/android/content/ComponentCallbacks` will be unregistered to `https://developer.android.com/reference/android/content/ContextWrapper#getBaseContext()`, and can be only used after `https://developer.android.com/reference/android/content/ContextWrapper#attachBaseContext(android.content.Context)`

| Parameters || |---|---| | `callback` | `ComponentCallbacks`: The interface to call. This can be either a `https://developer.android.com/reference/android/content/ComponentCallbacks` or `https://developer.android.com/reference/android/content/ComponentCallbacks2` interface.
| | Throws || |---|---| | `https://developer.android.com/reference/java/lang/IllegalStateException` | if this method calls before `https://developer.android.com/reference/android/content/ContextWrapper#attachBaseContext(android.content.Context)` | ### unregisterDeviceIdChangeListener Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void unregisterDeviceIdChangeListener (IntConsumer listener) ``` Removes a device ID changed listener from the Context. It's a no-op if the listener is not already registered.
| Parameters || |---|---| | `listener` | `IntConsumer`: This value cannot be `null`.
| ### unregisterReceiver Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void unregisterReceiver (BroadcastReceiver receiver) ``` Unregister a previously registered BroadcastReceiver. *All* filters that have been registered for this BroadcastReceiver will be removed.
| Parameters || |---|---| | `receiver` | `BroadcastReceiver`: The BroadcastReceiver to unregister.
| ### updateServiceBindings Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void updateServiceBindings (Collection params) ``` Perform a batch update of existing bindings. Existing bindings can be rebound with an updated set of flags, or unbound. Only flags returned from `https://developer.android.com/reference/android/content/Context#getUpdateableFlags()` may be added or removed. This API behaves as if the `https://developer.android.com/reference/android/content/Context#rebindService(android.content.ServiceConnection,%20android.content.Context.BindServiceFlags)` and `https://developer.android.com/reference/android/content/Context#unbindService(android.content.ServiceConnection)` API are called in the same order as the params are iterated.
| Parameters || |---|---| | `params` | `Collection`: This value cannot be `null`.
| ### updateServiceGroup Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void updateServiceGroup (ServiceConnection conn, int group, int importance) ``` For a service previously bound with `https://developer.android.com/reference/android/content/Context#bindService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` or a related method, change how the system manages that service's process in relation to other processes. This doesn't modify the original bind flags that were passed in when binding, but adjusts how the process will be managed in some cases based on those flags. Currently only works on isolated processes (will be ignored for non-isolated processes). Note that this call does not take immediate effect, but will be applied the next time the impacted process is adjusted for some other reason. Typically you would call this before then calling a new `https://developer.android.com/reference/android/content/Context#bindIsolatedService(android.content.Intent,%20android.content.Context.BindServiceFlags,%20java.lang.String,%20java.util.concurrent.Executor,%20android.content.ServiceConnection)` on the service of interest, with that binding causing the process to be shuffled accordingly.

| Parameters || |---|---| | `conn` | `ServiceConnection`: The connection interface previously supplied to bindService(). This parameter must not be null.
| | `group` | `int`: A group to put this connection's process in. Upon calling here, this will override any previous group that was set for that process. The group tells the system about processes that are logically grouped together, so should be managed as one unit of importance (such as when being considered a recently used app). All processes in the same app with the same group are considered to be related. Supplying 0 reverts to the default behavior of not grouping.
| | `importance` | `int`: Additional importance of the processes within a group. Upon calling here, this will override any previous importance that was set for that process. The most important process is 0, and higher values are successively less important. You can view this as describing how to order the processes in an array, with the processes at the end of the array being the least important. This value has no meaning besides indicating how processes should be ordered in that array one after the other. This provides a way to fine-tune the system's process killing, guiding it to kill processes at the end of the array first.
| ## Protected methods ### attachBaseContext Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` protected void attachBaseContext (Context base) ``` Set the base context for this ContextWrapper. All calls will then be delegated to the base context. Throws IllegalStateException if a base context has already been set.
| Parameters || |---|---| | `base` | `Context`: The new base context for this wrapper.
|
