BIND_ABOVE_CLIENT

Added in API level 14

public static final int BIND_ABOVE_CLIENT

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): indicates that the client application binding to this service considers the service to be more important than the app itself. When set, the platform will try to have the out of memory killer kill the app before it kills the service it is bound to, though this is not guaranteed to be the case.

Constant Value: 8 (0x00000008)

BIND_ADJUST_WITH_ACTIVITY

Added in API level 14

public static final int BIND_ADJUST_WITH_ACTIVITY

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): If binding from an activity, allow the target service's process importance to be raised based on whether the activity is visible to the user, regardless whether another flag is used to reduce the amount that the client process's overall importance is used to impact it.

Constant Value: 128 (0x00000080)

BIND_ALLOW_ACTIVITY_STARTS

Added in API level 34

public static final int BIND_ALLOW_ACTIVITY_STARTS

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): If binding from an app that is visible, the bound service is allowed to start an activity from background. This was the default behavior before SDK version Build.VERSION_CODES.UPSIDE_DOWN_CAKE. Since then, the default behavior changed to disallow the bound service to start a background activity even if the app bound to it is in foreground, unless this flag is specified when binding.

Constant Value: 512 (0x00000200)

BIND_ALLOW_OOM_MANAGEMENT

Added in API level 14

public static final int BIND_ALLOW_OOM_MANAGEMENT

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): allow the process hosting the bound service to go through its normal memory management. It will be treated more like a running service, allowing the system to (temporarily) expunge the process if low on memory or for some other whim it may have, and being more aggressive about making it a candidate to be killed (and restarted) if running for a long time.

Constant Value: 16 (0x00000010)

BIND_AUTO_CREATE

Added in API level 1

public static final int BIND_AUTO_CREATE

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): automatically create the service as long as the binding exists. Note that while this will create the service, its Service.onStartCommand(Intent, int, int) method will still only be called due to an explicit call to startService(Intent). Even without that, though, this still provides you with access to the service object while the service is created.

Note that prior to Build.VERSION_CODES.ICE_CREAM_SANDWICH, not supplying this flag would also impact how important the system consider's the target service's process to be. When set, the only way for it to be raised was by binding from a service in which case it will only be important when that activity is in the foreground. Now to achieve this behavior you must explicitly supply the new flag BIND_ADJUST_WITH_ACTIVITY. For compatibility, old applications that don't specify BIND_AUTO_CREATE will automatically have the flags BIND_WAIVE_PRIORITY and BIND_ADJUST_WITH_ACTIVITY set for them in order to achieve the same result.

Constant Value: 1 (0x00000001)

BIND_DEBUG_UNBIND

Added in API level 1

public static final int BIND_DEBUG_UNBIND

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): include debugging help for mismatched calls to unbind. When this flag is set, the callstack of the following unbindService(ServiceConnection) call is retained, to be printed if a later incorrect unbind call is made. Note that doing this requires retaining information about the binding that was made for the lifetime of the app, resulting in a leak -- this should only be used for debugging.

Constant Value: 2 (0x00000002)

BIND_EXTERNAL_SERVICE

Added in API level 24

public static final int BIND_EXTERNAL_SERVICE

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): The service being bound is an isolated, external service. This binds the service into the calling application's package, rather than the package in which the service is declared.

When using this flag, the code for the service being bound will execute under the calling application's package name and user ID. Because the service must be an isolated process, it will not have direct access to the application's data, though. The purpose of this flag is to allow applications to provide services that are attributed to the app using the service, rather than the application providing the service.

This flag is NOT compatible with BindServiceFlags. If you need to use BindServiceFlags, you must use BIND_EXTERNAL_SERVICE_LONG instead.

Constant Value: -2147483648 (0x80000000)

BIND_EXTERNAL_SERVICE_LONG

Added in API level 34

public static final long BIND_EXTERNAL_SERVICE_LONG

Works in the same way as BIND_EXTERNAL_SERVICE, but it's defined as a long value that is compatible to BindServiceFlags.

Constant Value: 4611686018427387904 (0x4000000000000000)

BIND_IMPORTANT

Added in API level 14

public static final int BIND_IMPORTANT

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): this service is very important to the client, so should be brought to the foreground process level when the client is. Normally a process can only be raised to the visibility level by a client, even if that client is in the foreground.

Constant Value: 64 (0x00000040)

BIND_INCLUDE_CAPABILITIES

Added in API level 29

public static final int BIND_INCLUDE_CAPABILITIES

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): If binding from an app that has specific capabilities due to its foreground state such as an activity or foreground service, then this flag will allow the bound app to get the same capabilities, as long as it has the required permissions as well. If binding from a top app and its target SDK version is at or above Build.VERSION_CODES.R, the app needs to explicitly use BIND_INCLUDE_CAPABILITIES flag to pass all capabilities to the service so the other app can have while-in-use access such as location, camera, microphone from background. If binding from a top app and its target SDK version is below Build.VERSION_CODES.R, BIND_INCLUDE_CAPABILITIES is implicit.

Constant Value: 4096 (0x00001000)

BIND_NOT_FOREGROUND

Added in API level 8

public static final int BIND_NOT_FOREGROUND

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): don't allow this binding to raise the target service's process to the foreground scheduling priority. It will still be raised to at least the same memory priority as the client (so that its process will not be killable in any situation where the client is not killable), but for CPU scheduling purposes it may be left in the background. This only has an impact in the situation where the binding client is a foreground process and the target service is in a background process.

Constant Value: 4 (0x00000004)

BIND_NOT_PERCEPTIBLE

Added in API level 29

public static final int BIND_NOT_PERCEPTIBLE

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): If binding from an app that is visible or user-perceptible, lower the target service's importance to below the perceptible level. This allows the system to (temporarily) expunge the bound process from memory to make room for more important user-perceptible processes.

Constant Value: 256 (0x00000100)

BIND_PACKAGE_ISOLATED_PROCESS

Added in API level 35

public static final int BIND_PACKAGE_ISOLATED_PROCESS

Flag for bindIsolatedService(Intent, BindServiceFlags, String, Executor, ServiceConnection): Bind the service into a shared isolated process, but only with other isolated services from the same package that declare the same process name.

Specifying this flag allows multiple isolated services defined in the same package to be running in a single shared isolated process. This shared isolated process must be specified since this flag will not work with the default application process.

This flag is different from BIND_SHARED_ISOLATED_PROCESS since it only allows binding services from the same package in the same shared isolated process. This also means the shared package isolated process is global, and not scoped to each potential calling app.

The shared isolated process instance is identified by the "android:process" attribute defined by the service. This flag cannot be used without this attribute set.

Constant Value: 16384 (0x00004000)

BIND_SHARED_ISOLATED_PROCESS

Added in API level 34

public static final int BIND_SHARED_ISOLATED_PROCESS

Flag for bindIsolatedService(Intent, BindServiceFlags, String, Executor, ServiceConnection): Bind the service into a shared isolated process. Specifying this flag allows multiple isolated services to be running in a single shared isolated process. The shared isolated process instance is identified by the instanceName parameter in bindIsolatedService(android.content.Intent, int, java.lang.String, java.util.concurrent.Executor, android.content.ServiceConnection). Subsequent calls to bindIsolatedService(Intent, BindServiceFlags, String, Executor, ServiceConnection) with the same instanceName will cause the isolated service to be co-located in the same shared isolated process. Note that the shared isolated process is scoped to the calling app; once created, only the calling app can bind additional isolated services into the shared process. However, the services themselves can come from different APKs and therefore different vendors. Only services that set the R.attr.allowSharedIsolatedProcess attribute to true are allowed to be bound into a shared isolated process.

Constant Value: 8192 (0x00002000)

BIND_WAIVE_PRIORITY

Added in API level 14

public static final int BIND_WAIVE_PRIORITY

Flag for bindService(Intent, BindServiceFlags, Executor, ServiceConnection): don't impact the scheduling or memory management priority of the target service's hosting process. Allows the service's process to be managed on the background LRU list just like a regular application process in the background.

Constant Value: 32 (0x00000020)

MODE_MULTI_PROCESS

Added in API level 11
Deprecated in API level 23

public static final int MODE_MULTI_PROCESS

This constant was deprecated in API level 23.
MODE_MULTI_PROCESS does not work reliably in some versions of Android, and furthermore does not provide any mechanism for reconciling concurrent modifications across processes. Applications should not attempt to use it. Instead, they should use an explicit cross-process data management approach such as ContentProvider.

SharedPreference loading flag: when set, the file on disk will be checked for modification even if the shared preferences instance is already loaded in this process. This behavior is sometimes desired in cases where the application has multiple processes, all writing to the same SharedPreferences file. Generally there are better forms of communication between processes, though.

This was the legacy (but undocumented) behavior in and before Gingerbread (Android 2.3) and this flag is implied when targeting such releases. For applications targeting SDK versions greater than Android 2.3, this flag must be explicitly set if desired.

MODE_WORLD_READABLE

Added in API level 1
Deprecated in API level 17

public static final int MODE_WORLD_READABLE

This constant was deprecated in API level 17.
Creating world-readable files is very dangerous, and likely to cause security holes in applications.

There are no guarantees that this access mode will remain on a file, such as when it goes through a backup and restore.

File creation mode: allow all other applications to have read access to the created file.

Starting from Build.VERSION_CODES.N, attempting to use this mode throws a SecurityException.

bindIsolatedService

Added in API level 29

public boolean bindIsolatedService (Intent service, 
                int flags, 
                String instanceName, 
                Executor executor, 
                ServiceConnection conn)

Variation of bindService(Intent, BindServiceFlags, Executor, 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 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 updateServiceGroup(android.content.ServiceConnection, int, int) 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 `bindService(Intent, BindServiceFlags, Executor, 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 `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `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 `bindService(Intent, BindServiceFlags, Executor, ServiceConnection)`.

Throws
`SecurityException`	If the caller does not have permission to access the service
`IllegalArgumentException`	If the instanceName is invalid.

                Executor executor, 
                ServiceConnection conn)

Same as bindService(Intent, ServiceConnection, int) with executor to control ServiceConnection callbacks.

This method only accepts a 32 bits flag, to pass in a 64 bits flag, call bindService(android.content.Intent, android.content.Context.BindServiceFlags, java.util.concurrent.Executor, android.content.ServiceConnection) instead.

bindService

Added in API level 1

public abstract 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 onBind() method. If it does, then the ServiceConnection's onNullBinding() method will be invoked instead of onServiceConnected().

Note: This method cannot be called from a BroadcastReceiver component. A pattern you can use to communicate from a BroadcastReceiver to a Service is to call startService(Intent) with the arguments containing the command to be sent, with the service calling its 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 registerReceiver(BroadcastReceiver, 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 bindService(android.content.Intent, android.content.ServiceConnection, android.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:

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 `unbindService(ServiceConnection)` to release the connection.

Throws
`SecurityException`	If the caller does not have permission to access the service or the service cannot be found. Call `unbindService(ServiceConnection)` to release the connection when this exception is thrown.

Binds to a service in the given user in the same manner as bindService(Intent, BindServiceFlags, Executor, 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 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`.
`conn`	`ServiceConnection`: Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.

checkCallingUriPermission(Uri, int)

checkCallingPermission

Added in API level 1

public abstract int checkCallingPermission (String permission)

Determine whether the calling process of an IPC you are handling has been granted a particular permission. This is basically the same as calling checkPermission(java.lang.String, int, int) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail. This is done to protect against accidentally leaking permissions; you can use checkCallingOrSelfPermission(String) to avoid this protection.

Parameters
`permission`	`String`: The name of the permission being checked. This value cannot be `null`.

Returns
`int`	`PackageManager.PERMISSION_GRANTED` if the calling pid/uid is allowed that permission, or `PackageManager.PERMISSION_DENIED` if it is not. Value is `PackageManager.PERMISSION_GRANTED`, or `PackageManager.PERMISSION_DENIED`

This is basically the same as calling checkUriPermission(android.net.Uri, int, int, int) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail.

Parameters
`uri`	`Uri`: The uri that is being checked.
`modeFlags`	`int`: The access modes to check. Value is either `0` or a combination of `Intent.FLAG_GRANT_READ_URI_PERMISSION`, and `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`

Determine whether the calling process and uid has been granted permission to access a list of URIs. This is basically the same as calling checkUriPermissions(java.util.List, int, int, int) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail.

Parameters
`uris`	`List`: The list of URIs that is being checked. This value cannot be `null`.

                int pid, 
                int uid, 
                int modeFlags)

Determine whether a particular process and uid has been granted permission to access a specific content URI.

Unlike checkUriPermission(android.net.Uri, int, int, int), this method checks for general access to the URI's content provider, as well as explicitly granted permissions.

Note, this check will throw an IllegalArgumentException for non-content URIs.

checkUriPermission

Added in API level 1

public abstract int checkUriPermission (Uri uri, 
                int pid, 
                int uid, 
                int modeFlags)

Determine whether a particular process and uid has been granted permission to access a specific URI. 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.

                int uid, 
                int modeFlags)

Determine whether a particular process and uid has been granted permission to access a list of URIs. 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. Note: On SDK Version Build.VERSION_CODES.S, calling this method from a secondary-user's context will incorrectly return PackageManager.PERMISSION_DENIED for all {code uris}.

createConfigurationContext

Added in API level 17

public abstract 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 `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.

`splitName`	`String`: The name of the split to include, as declared in the split's `AndroidManifest.xml`.

Returns
`Context`	A `Context` with the given split's code and/or resources loaded.

Throws
`PackageManager.NameNotFoundException`

createDeviceContext

Added in API level 34

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 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 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
`Context`	A context associated with the given device ID. This value cannot be `null`.

Throws
`IllegalArgumentException`	if the given device ID is not a valid ID of the default device or a virtual device.

createDeviceProtectedStorageContext

Added in API level 24

public abstract 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
`Context`

isDeviceProtectedStorage()

createDisplayContext

Added in API level 17

public abstract 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 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 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 WindowManager instance.

To obtain an instance of WindowManager configured to show windows on the given display, call createWindowContext(int, android.os.Bundle) on the returned display context, then call getSystemService(java.lang.String) or 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
`Context`	A context for the display.

createPackageContext

Added in API level 1

public abstract 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 PackageManager.NameNotFoundException if there is no application with the given package name.

Throws SecurityException if the Context requested can not be loaded into the caller's process for security reasons (see 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 `CONTEXT_INCLUDE_CODE`, `CONTEXT_IGNORE_SECURITY`, `CONTEXT_RESTRICTED`, android.content.Context.CONTEXT_DEVICE_PROTECTED_STORAGE, android.content.Context.CONTEXT_CREDENTIAL_PROTECTED_STORAGE, and android.content.Context.CONTEXT_REGISTER_PACKAGE

Returns
`Context`	A `Context` for the application.

Throws
`SecurityException`
`PackageManager.NameNotFoundException`	if there is no application with the given package name.

createWindowContext

Added in API level 30

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 WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY. A window context must be created from a context that has an associated Display, such as Activity or a context created with createDisplayContext(android.view.Display).

The window context is created with the appropriate Configuration for the area of the display that the windows created with it can occupy; it must be used when inflating views, such that they can be inflated with proper 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 Build.VERSION_CODES.S, window context provides the capability to receive configuration changes for existing token by overriding the token of the WindowManager.LayoutParams passed in WindowManager.addView(View, 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 Build.VERSION_CODES.R didn't have this capability. This is a no-op for the window context in 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 Build.VERSION_CODES.S, window context provides the capability to listen to its Configuration changes by calling registerComponentCallbacks(android.content.ComponentCallbacks), while other kinds of Context will register the ComponentCallbacks to its Application context. Note that window context only propagate ComponentCallbacks.onConfigurationChanged(Configuration) callback. ComponentCallbacks.onLowMemory() or other callbacks in ComponentCallbacks2 won't be invoked.

Note that using Application or 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 Configuration changes for the visual container.

Added in API level 1

public abstract 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 SecurityException. This is the same as enforceCallingPermission(String, 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`: A message to include in the exception if it is thrown. This value may be `null`.

See also:

checkCallingOrSelfPermission(String)

Added in API level 1

public abstract 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 SecurityException. This is the same as enforceCallingUriPermission(Uri, int, 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 `Intent.FLAG_GRANT_READ_URI_PERMISSION`, and `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`

enforceCallingPermission

Added in API level 1

public abstract 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 SecurityException. This is basically the same as calling enforcePermission(java.lang.String, int, int, java.lang.String) with the pid and uid returned by Binder.getCallingPid() and 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 enforceCallingOrSelfPermission(String, String) to avoid this protection.

Parameters
`permission`	`String`: The name of the permission being checked. This value cannot be `null`.
`message`	`String`: A message to include in the exception if it is thrown. This value may be `null`.

See also:

                int modeFlags, 
                String message)

If the calling process and uid has not been granted permission to access a specific URI, throw SecurityException. This is basically the same as calling enforceUriPermission(android.net.Uri, int, int, int, java.lang.String) with the pid and uid returned by Binder.getCallingPid() and 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 `Intent.FLAG_GRANT_READ_URI_PERMISSION`, and `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`

fileList

Added in API level 1

public abstract String[] fileList ()

Returns an array of strings naming the private files associated with this Context's application package.

Returns
`String[]`	Array of strings naming the private files.

See also:

getApplicationContext

Added in API level 1

public abstract 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 registerReceiver(android.content.BroadcastReceiver, android.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
`Context`

getApplicationInfo

Added in API level 4

public abstract ApplicationInfo getApplicationInfo ()

Return the full application info for this context's package.

Returns
`ApplicationInfo`

getAssets

Added in API level 1

public abstract 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 getResources(). For example, they should share the same Configuration object.

Returns
`AssetManager`	an AssetManager instance for the application's package

See also:

getResources()

getAttributionSource

Added in API level 31

public AttributionSource getAttributionSource ()

Returns
`AttributionSource`	The identity of this context for permission purposes. This value cannot be `null`.

See also:

AttributionSource

getAttributionTag

Added in API level 30

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
`String`	the attribution tag this context is for or `null` if this is the default.

getCacheDir

Added in API level 1

public abstract 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 File.lastModified(). If desired, you can exert more control over how files are deleted using StorageManager.setCacheBehaviorGroup(File, boolean) and StorageManager.setCacheBehaviorTombstone(File, boolean).

Apps are strongly encouraged to keep their usage of cache space below the quota returned by 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
`File`	The path of the directory holding application cache files.

See also:

getClassLoader

Added in API level 1

public abstract ClassLoader getClassLoader ()

Return a class loader you can use to retrieve classes in this package.

Returns
`ClassLoader`

getCodeCacheDir

Added in API level 21

public abstract 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
`File`	The path of the directory holding application code cache files.

getColor

Added in API level 23

public final int getColor (int id)

Returns a color associated with a particular resource ID and styled for the current theme.

Parameters
`id`	`int`: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.

Returns
`int`	A single color value in the form 0xAARRGGBB.

Throws
`Resources.NotFoundException`	if the given ID does not exist.

getColorStateList

Added in API level 23

public final ColorStateList getColorStateList (int id)

Returns a color state list associated with a particular resource ID and styled for the current theme.

Parameters
`id`	`int`: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.

Returns
`ColorStateList`	A color state list. This value cannot be `null`.

Throws
`Resources.NotFoundException`	if the given ID does not exist.

getContentResolver

Added in API level 1

public abstract ContentResolver getContentResolver ()

Return a ContentResolver instance for your application's package.

Returns
`ContentResolver`

getDataDir

Added in API level 24

public abstract 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 getFilesDir(), getCacheDir(), getDir(java.lang.String, int), 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
`File`

See also:

ApplicationInfo.dataDir

getDatabasePath

Added in API level 1

public abstract File getDatabasePath (String name)

Returns the absolute path on the filesystem where a database created with openOrCreateDatabase(String, int, 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
`File`	An absolute path to the given database.

See also:

openOrCreateDatabase(String, int, CursorFactory)

getDeviceId

Added in API level 34

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 Context.DEVICE_ID_DEFAULT

If the underlying device ID is changed by the system, for example, when an Activity is moved to a different virtual device, applications can register to listen to changes by calling Context.registerDeviceIdChangeListener(Executor, IntConsumer).

This method will only return a reliable value for this instance if it was created with Context.createDeviceContext(int), or if this instance is a UI or Display Context. Contexts created with 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, 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

public abstract 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 `MODE_PRIVATE`, `MODE_WORLD_READABLE`, `MODE_WORLD_WRITEABLE`, and `MODE_APPEND`

Returns
`File`	A `File` object for the requested directory. The directory will have been created if it does not already exist.

openFileOutput(String, int)

getDisplay

Added in API level 30

public Display getDisplay ()

Get the display this context is associated with. Applications should use this method with Activity or a context associated with a Display via createDisplayContext(android.view.Display) to get a display object associated with a Context, or DisplayManager.getDisplay(int) to get a display object by id.

Returns
`Display`	Returns the `Display` object this context is associated with. This value cannot be `null`.

Throws
`UnsupportedOperationException`	if the method is called on an instance that is not associated with any display.

getDrawable

Added in API level 21

public final Drawable getDrawable (int id)

Returns a drawable object associated with a particular resource ID and styled for the current theme.

Parameters
`id`	`int`: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.

Returns
`Drawable`	An object that can be used to draw this resource. This value may be `null`.

Throws
`Resources.NotFoundException`	if the given ID does not exist.

getExternalCacheDir

Added in API level 8

public abstract 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 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 Build.VERSION_CODES.JELLY_BEAN_MR1 or later and Environment.isExternalStorageEmulated(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 Environment.getExternalStorageState(File).
There is no security enforced with these files. For example, any application holding Manifest.permission.WRITE_EXTERNAL_STORAGE can write to these files.

If a shared storage device is emulated (as determined by Environment.isExternalStorageEmulated(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 getCacheDir().

Starting in 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, Manifest.permission.WRITE_EXTERNAL_STORAGE and/or Manifest.permission.READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by 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
`File`	the absolute path to application-specific directory. May return `null` if shared storage is not currently available.

getExternalCacheDirs

Added in API level 19

public abstract 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 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 Build.VERSION_CODES.JELLY_BEAN_MR1 or later and Environment.isExternalStorageEmulated(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 Environment.getExternalStorageState(File).
There is no security enforced with these files. For example, any application holding 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 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
`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 `getExternalCacheDir()`.

getExternalFilesDir

Added in API level 8

public abstract 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 getFilesDir() in that these files will be deleted when the application is uninstalled, however there are some important differences:

On devices with multiple users (as described by 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 MediaScannerConnection.scanFile. Note that this is not the same as Environment.getExternalStoragePublicDirectory(), 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 Environment.getExternalStoragePublicDirectory(), 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.  If
    // external storage is not currently mounted this will think the
    // picture doesn't exist.
    File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    if (path != null) {
        File file = new File(path, "DemoPicture.jpg");
        return file.exists();
    }
    return false;
}

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: `Environment.DIRECTORY_MUSIC`, `Environment.DIRECTORY_PODCASTS`, `Environment.DIRECTORY_RINGTONES`, `Environment.DIRECTORY_ALARMS`, `Environment.DIRECTORY_NOTIFICATIONS`, `Environment.DIRECTORY_PICTURES`, or `Environment.DIRECTORY_MOVIES`.

Returns

getExternalMediaDirs

Added in API level 21
Deprecated in API level 30

public abstract File[] getExternalMediaDirs ()

This method was deprecated in API level 30.
These directories still exist and are scanned, but developers are encouraged to migrate to inserting content into a MediaStore collection directly, as any app can contribute new media to MediaStore with no permissions required, starting in 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 MediaStore.

This is like getExternalFilesDirs(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 Environment.getExternalStorageState(File).
There is no security enforced with these files. For example, any application holding Manifest.permission.WRITE_EXTERNAL_STORAGE can write to these files.

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 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
`File[]`	the absolute paths to application-specific directories. Some individual paths may be `null` if that shared storage is not currently available.

See also:

getFileStreamPath

Added in API level 1

public abstract File getFileStreamPath (String name)

Returns the absolute path on the filesystem where a file created with openFileOutput(String, int) 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
`File`	An absolute path to the given file.

See also:

getFilesDir

Added in API level 1

public abstract File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) 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
`File`	The path of the directory holding application files.

See also:

getMainExecutor

Added in API level 28

public Executor getMainExecutor ()

Return an 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
`Executor`

getMainLooper

Added in API level 1

public abstract 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 Looper.getMainLooper().

Returns
`Looper`	The main looper.

getNoBackupFilesDir

Added in API level 21

public abstract File getNoBackupFilesDir ()

Returns the absolute path to the directory on the filesystem similar to getFilesDir(). The difference is that files placed under this directory will be excluded from automatic backup to remote storage. See 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
`File`	The path of the directory holding application files that will not be automatically backed up to remote storage.

See also:

getObbDir

Added in API level 11

public abstract 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 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 Environment.getExternalStorageState(File).
There is no security enforced with these files. For example, any application holding Manifest.permission.WRITE_EXTERNAL_STORAGE can write to these files.

Starting in Build.VERSION_CODES.KITKAT, no permissions are required to read or write to the path that this method returns. However, starting from Build.VERSION_CODES.M, to read the OBB expansion files, you must declare the Manifest.permission.READ_EXTERNAL_STORAGE permission in the app manifest and ask for permission at runtime as follows:

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="23" />

Starting from Build.VERSION_CODES.N, 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 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 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
`File`	the absolute path to application-specific directory. May return `null` if shared storage is not currently available.

See also:

getObbDirs

Added in API level 19

public abstract 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.

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
`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 `getObbDir()`

See also:

getOpPackageName

Added in API level 29

public String getOpPackageName ()

Return the package name that should be used for 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
`String`	This value cannot be `null`.

getPackageCodePath

Added in API level 8

public abstract 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
`String`	String Path to the code and assets.

getPackageManager

Added in API level 1

public abstract PackageManager getPackageManager ()

Return PackageManager instance to find global package information.

Returns
`PackageManager`

getPackageName

Added in API level 1

public abstract String getPackageName ()

Return the name of this application's package.

Returns
`String`

getPackageResourcePath

Added in API level 8

public abstract 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
`String`	String Path to the resources.

getParams

Added in API level 31

public ContextParams getParams ()

Return the set of parameters which this Context was created with, if it was created via createContext(android.content.ContextParams).

Returns
`ContextParams`	This value may be `null`.

getResources

Added in API level 1

public abstract 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 getAssets(). For example, they should share the same Configuration object.

Returns
`Resources`	a Resources instance for the application's package

See also:

getAssets()

getSharedPreferences

Added in API level 1

public abstract 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 (SharedPreferences.edit()) and then commit changes (SharedPreferences.Editor.commit() or SharedPreferences.Editor.apply()).

Parameters
`name`	`String`: Desired preferences file.
`mode`	`int`: Operating mode. Value is either `0` or a combination of `MODE_PRIVATE`, `MODE_WORLD_READABLE`, `MODE_WORLD_WRITEABLE`, and `MODE_MULTI_PROCESS`

Returns
`SharedPreferences`	The single `SharedPreferences` instance that can be used to retrieve and modify the preference values.

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 PackageManager.isInstantApp() returns true, don't have access to the following system services: DEVICE_POLICY_SERVICE, FINGERPRINT_SERVICE, KEYGUARD_SERVICE, SHORTCUT_SERVICE, USB_SERVICE, WALLPAPER_SERVICE, WIFI_P2P_SERVICE, WIFI_SERVICE, 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.

Parameters
`serviceClass`	`Class`: The class of the desired service. This value cannot be `null`.

Returns
`T`	The service or `null` if the class is not a supported system service. Note: never throw a `RuntimeException` if the name is not supported.

getSystemService

public abstract 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:

WINDOW_SERVICE ("window"): The top-level window manager in which you can place custom windows. The returned object is a WindowManager. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.
LAYOUT_INFLATER_SERVICE ("layout_inflater"): A LayoutInflater for inflating layout resources in this context. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.

grantUriPermission

Added in API level 1

public abstract 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 Intent.FLAG_GRANT_READ_URI_PERMISSION or 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 revokeUriPermission(Uri, int) when the target should no longer be allowed to access it.

To succeed, the content provider owning the Uri must have set the grantUriPermissions attribute in its manifest or included the <grant-uri-permissions> 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. Value is either `0` or a combination of `Intent.FLAG_GRANT_READ_URI_PERMISSION`, `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`, `Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION`, and `Intent.FLAG_GRANT_PREFIX_URI_PERMISSION`

isUiContext

Added in API level 31

public boolean isUiContext ()

Returns true if the context is a UI context which can access UI components such as WindowManager, LayoutInflater or WallpaperManager. Accessing UI components from non-UI contexts throws Violation if StrictMode.VmPolicy.Builder.detectIncorrectContextUse() is enabled.

Examples of UI contexts are an Activity, a context created from createWindowContext(int, android.os.Bundle) or InputMethodService

Note that even if it is allowed programmatically, it is not suggested to override this method to bypass IncorrectContextUseViolation verification.

Returns
`boolean`

The database must be closed before being moved.

Parameters
`sourceContext`	`Context`: The source context which contains the existing database to move.
`name`	`String`: The name of the database file.

Returns
`boolean`	`true` if the move was successful or if the database didn't exist in the source context, otherwise `false`.

Added in API level 1
Deprecated in API level 15

public abstract Drawable peekWallpaper ()

This method was deprecated in API level 15.
Use WallpaperManager.peek() instead.

Returns
`Drawable`

registerComponentCallbacks

Added in API level 14

public void registerComponentCallbacks (ComponentCallbacks callback)

Add a new ComponentCallbacks to the base application of the Context, which will be called at the same times as the ComponentCallbacks methods of activities and other components are called. Note that you must be sure to use unregisterComponentCallbacks(ComponentCallbacks) when appropriate in the future; this will not be removed for you.

After Build.VERSION_CODES.S, registering the ComponentCallbacks to Context created via createWindowContext(int, android.os.Bundle) or createWindowContext(android.view.Display, int, android.os.Bundle) will receive ComponentCallbacks.onConfigurationChanged(Configuration) from Window Context rather than its base application. It is helpful if you want to handle UI components that associated with the Window Context when the Window Context has configuration changes.

After Build.VERSION_CODES.TIRAMISU, registering the ComponentCallbacks to Activity context will receive ComponentCallbacks.onConfigurationChanged(Configuration) from Activity.onConfigurationChanged(Configuration) rather than its base application.

After Build.VERSION_CODES.UPSIDE_DOWN_CAKE, registering the ComponentCallbacks to InputMethodService will receive ComponentCallbacks.onConfigurationChanged(Configuration) from InputmethodService rather than its base application. It is helpful if you want to handle UI components when the IME has configuration changes.

Parameters
`callback`	`ComponentCallbacks`: The interface to call. This can be either a `ComponentCallbacks` or `ComponentCallbacks2` interface.

See also:

createWindowContext(int, Bundle)

registerDeviceIdChangeListener

Added in API level 34

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 Configuration.

Parameters

executor

Executor: The Executor on whose thread to execute the callbacks of the listener object. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

listener

IntConsumer: The listener IntConsumer to call which will receive the updated device ID. This value cannot be null.

registerReceiver

Added in API level 1

public abstract 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 your 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 BroadcastReceiver for more information on Intent broadcasts.

As of Build.VERSION_CODES.UPSIDE_DOWN_CAKE, the system can place context-registered broadcasts in a queue while the app is in the cached state. 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 Build.VERSION_CODES.ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the Intent.setPackage(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 Build.VERSION_CODES.UPSIDE_DOWN_CAKE, either RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED must be specified if the receiver is not being registered for system broadcasts or a SecurityException will be thrown. See registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter, int) to register a receiver with flags.

Note: this method cannot be called from a 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 registerReceiver(BroadcastReceiver, IntentFilter), since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.

Parameters
`receiver`	`BroadcastReceiver`: The BroadcastReceiver to handle the broadcast. This value may be `null`.
`filter`	`IntentFilter`: Selects the Intent broadcasts to be received.

Returns
`Intent`	The first sticky intent found that matches `filter`, or null if there are none.

registerReceiver

Added in API level 26

public abstract Intent registerReceiver (BroadcastReceiver receiver, 
                IntentFilter filter, 
                int flags)

Register to receive intent broadcasts, with the receiver optionally being exposed to Instant Apps. See registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter) for more information. By default Instant Apps cannot interact with receivers in other applications, this allows you to expose a receiver that Instant Apps can interact with.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
`receiver`	`BroadcastReceiver`: The BroadcastReceiver to handle the broadcast. This value may be `null`.
`filter`	`IntentFilter`: Selects the Intent broadcasts to be received.
`flags`	`int`: Additional options for the receiver. For apps targeting `Build.VERSION_CODES.UPSIDE_DOWN_CAKE` either `RECEIVER_EXPORTED` or `RECEIVER_NOT_EXPORTED` must be specified if the receiver isn't being registered for system broadcasts or a `SecurityException` will be thrown. If `RECEIVER_EXPORTED` is specified, a receiver may additionally specify `RECEIVER_VISIBLE_TO_INSTANT_APPS`. For a complete list of system broadcast actions, see the BROADCAST_ACTIONS.TXT file in the Android SDK. If both `RECEIVER_EXPORTED` and `RECEIVER_NOT_EXPORTED` are specified, an `IllegalArgumentException` will be thrown. Value is either `0` or a combination of `RECEIVER_VISIBLE_TO_INSTANT_APPS`, `RECEIVER_EXPORTED`, `RECEIVER_NOT_EXPORTED`, and android.content.Context.RECEIVER_EXPORTED_UNAUDITED

Returns
`Intent`	The first sticky intent found that matches `filter`, or null if there are none.

                String broadcastPermission, 
                Handler scheduler, 
                int flags)

Register to receive intent broadcasts, to run in the context of scheduler. See registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter, int) and registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter, java.lang.String, android.os.Handler) for more information.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
`receiver`	`BroadcastReceiver`: The BroadcastReceiver to handle the broadcast.

For apps targeting `Build.VERSION_CODES.UPSIDE_DOWN_CAKE` either `RECEIVER_EXPORTED` or `RECEIVER_NOT_EXPORTED` must be specified if the receiver isn't being registered for system broadcasts or a `SecurityException` will be thrown. If `RECEIVER_EXPORTED` is specified, a receiver may additionally specify `RECEIVER_VISIBLE_TO_INSTANT_APPS`. For a complete list of system broadcast actions, see the BROADCAST_ACTIONS.TXT file in the Android SDK. If both `RECEIVER_EXPORTED` and `RECEIVER_NOT_EXPORTED` are specified, an `IllegalArgumentException` will be thrown.

                IntentFilter filter, 
                String broadcastPermission, 
                Handler scheduler)

Register to receive intent broadcasts, to run in the context of scheduler. See registerReceiver(android.content.BroadcastReceiver, android.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 BroadcastReceiver for more information on Intent broadcasts.

Parameters
`receiver`	`BroadcastReceiver`: The BroadcastReceiver to handle the broadcast.
`filter`	`IntentFilter`: Selects the Intent broadcasts to be received.
`broadcastPermission`	`String`: String naming a permissions that a broadcaster must hold in order to send an Intent to you. If null, no permission is required.
`scheduler`	`Handler`: Handler identifying the thread that will receive the Intent. If null, the main thread of the process will be used.

Returns
`Intent`	The first sticky intent found that matches `filter`, or null if there are none.

removeStickyBroadcast

Added in API level 1
Deprecated in API level 21

public abstract void removeStickyBroadcast (Intent intent)

This method was deprecated in API level 21.
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 sendStickyBroadcast(Intent), so that it is as if the sticky broadcast had never happened.
Requires Manifest.permission.BROADCAST_STICKY

Parameters
`intent`	`Intent`: The Intent that was previously broadcast.

See also:

sendStickyBroadcast(Intent)

removeStickyBroadcastAsUser

Added in API level 17
Deprecated in API level 21

public abstract void removeStickyBroadcastAsUser (Intent intent, 
                UserHandle user)

Version of 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 Manifest.permission.BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.
Requires android.Manifest.permission.INTERACT_ACROSS_USERS and Manifest.permission.BROADCAST_STICKY

Parameters
`intent`	`Intent`: The Intent that was previously broadcast.
`user`	`UserHandle`: UserHandle to remove the sticky broadcast from.

See also:

sendStickyBroadcastAsUser(Intent, UserHandle)

revokeSelfPermissionOnKill

Added in API level 33

public void revokeSelfPermissionOnKill (String permName)

Triggers the asynchronous revocation of a runtime permission. If the permission is not currently granted, nothing happens (even if later granted by the user).

Parameters
`permName`	`String`: The name of the permission to be revoked. This value cannot be `null`.

Throws
`IllegalArgumentException`	if the permission is not a runtime permission

See also:

revokeSelfPermissionsOnKill(Collection)

revokeSelfPermissionsOnKill

Added in API level 33

public void revokeSelfPermissionsOnKill (Collection<String> 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 PackageManager.getGroupOfPlatformPermission(String, Executor, Consumer) and PackageManager.getPlatformPermissionsForGroup(String, Executor, 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`: Collection of permissions to be revoked. This value cannot be `null`.

Throws
`IllegalArgumentException`	if any of the permissions is not a runtime permission

See also:

revokeUriPermission

Added in API level 1

public abstract void revokeUriPermission (Uri uri, 
                int modeFlags)

Remove all permissions to access a particular content provider Uri that were previously added with grantUriPermission(String, Uri, int) 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 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 SecurityException would be thrown. As of 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 revokeUriPermission(java.lang.String, android.net.Uri, int), 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 `Intent.FLAG_GRANT_READ_URI_PERMISSION`, and `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`

See also:

grantUriPermission(String, Uri, int)

revokeUriPermission

Added in API level 26

public abstract void revokeUriPermission (String toPackage, 
                Uri uri, 
                int modeFlags)

Remove permissions to access a particular content provider Uri that were previously added with grantUriPermission(String, Uri, int) 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 revokeUriPermission(android.net.Uri, int), this method will only revoke permissions that had been explicitly granted through grantUriPermission(String, Uri, int) 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
`toPackage`	`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 `Intent.FLAG_GRANT_READ_URI_PERMISSION`, and `Intent.FLAG_GRANT_WRITE_URI_PERMISSION`

                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. If you want to allow receivers to propagate results or abort the broadcast, you must send an ordered broadcast using sendOrderedBroadcast(android.content.Intent, java.lang.String).

See 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`: (optional) String naming a permission that a receiver must hold in order to receive your broadcast. If null, no permission is required.
`options`	`Bundle`: (optional) Additional sending options, generated from a `BroadcastOptions`. This value may be `null`.

sendStickyBroadcast

Added in API level 1
Deprecated in API level 21

public abstract void sendStickyBroadcast (Intent intent)

Perform a 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 registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter). In all other ways, this behaves the same as sendBroadcast(android.content.Intent).
Requires 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.

See also:

sendStickyBroadcast

Added in API level 31
Deprecated in API level 31

public void sendStickyBroadcast (Intent intent, 
                Bundle options)

This method was deprecated in API level 31.
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.

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 `BroadcastOptions`. This value may be `null`.

Requires android.Manifest.permission.INTERACT_ACROSS_USERS and 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.

setTheme

Added in API level 1

public abstract 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 Activity.setContentView(View) or LayoutInflater.inflate(int, ViewGroup)).

Parameters
`resid`	`int`: The style resource describing the theme.

setWallpaper

Added in API level 1
Deprecated in API level 15

public abstract void setWallpaper (Bitmap bitmap)

This method was deprecated in API level 15.
Use WallpaperManager.set() instead.

This method requires the caller to hold the permission Manifest.permission.SET_WALLPAPER.

Parameters
`bitmap`	`Bitmap`

Throws
`IOException`

setWallpaper

Added in API level 1
Deprecated in API level 15

public abstract void setWallpaper (InputStream data)

This method was deprecated in API level 15.
Use WallpaperManager.set() instead.

This method requires the caller to hold the permission Manifest.permission.SET_WALLPAPER.

Parameters
`data`	`InputStream`

Throws
`IOException`

startActivities

Added in API level 16

public abstract void startActivities (Intent[] intents, 
                Bundle options)

Launch multiple new activities. This is generally the same as calling startActivity(android.content.Intent) for the first Intent in the array, that activity during its creation calling 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 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`: Additional options for how the Activity should be started. See `startActivity(Intent, Bundle)` Context.startActivity(Intent, Bundle)} for more details.

Throws
`ActivityNotFoundException`

See also:

startActivities

Added in API level 11

public abstract void startActivities (Intent[] intents)

Same as startActivities(android.content.Intent[], android.os.Bundle) with no options specified.

Parameters
`intents`	`Intent`: An array of Intents to be started.

Throws
`ActivityNotFoundException`

See also:

startActivity

Added in API level 1

public abstract void startActivity (Intent intent)

Same as startActivity(android.content.Intent, android.os.Bundle) with no options specified.

Parameters
`intent`	`Intent`: The description of the activity to start.

Throws
`ActivityNotFoundException`	`

See also:

startActivity

Added in API level 16

public abstract 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 Activity Context, then the Intent must include the 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 ActivityNotFoundException if there was no Activity found to run the given Intent.

Parameters
`intent`	`Intent`: The description of the activity to start.
`options`	`Bundle`: Additional options for how the Activity should be started. May be null if there are no options. See `ActivityOptions` for how to build the Bundle supplied here; there are no supported definitions for building it manually.

Throws
`ActivityNotFoundException`

See also:

startForegroundService

Added in API level 26

public abstract ComponentName startForegroundService (Intent service)

Similar to startService(android.content.Intent), but with an implicit promise that the Service will call startForeground(int, android.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 Build.VERSION_CODES.S or later. On older Android versions, an internal exception RemoteServiceException is logged instead, with a corresponding message.

Unlike the ordinary 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 Build.VERSION_CODES.S, apps targeting SDK Version Build.VERSION_CODES.S or higher are not allowed to start foreground services from the background. See Behavior changes: Apps targeting Android 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
`ComponentName`	If the service is being started or is already running, the `ComponentName` of the actual service that was started is returned; else if the service does not exist null is returned.

Throws
`SecurityException`	If the caller does not have permission to access the service or the service can not be found.
`ForegroundServiceStartNotAllowedException`	If the caller app's targeting API is `Build.VERSION_CODES.S` or later, and the foreground service is restricted from start due to background restriction.

startInstrumentation

Added in API level 1

public abstract boolean startInstrumentation (ComponentName className, 
                String profileFile, 
                Bundle arguments)

Start executing an 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`: Optional path to write profiling data as the instrumentation runs, or null for no profiling.
`arguments`	`Bundle`: Additional optional arguments to pass to the instrumentation, or null.

Returns
`boolean`	`true` if the instrumentation was successfully started, else `false` if it could not be found.

startIntentSender

Added in API level 16

public abstract void startIntentSender (IntentSender intent, 
                Intent fillInIntent, 
                int flagsMask, 
                int flagsValues, 
                int extraFlags, 
                Bundle options)

Like startActivity(android.content.Intent, android.os.Bundle), but taking a IntentSender to start. If the IntentSender is for an activity, that activity will be started as if you had called the regular startActivity(android.content.Intent) here; otherwise, its associated action will be executed (such as sending a broadcast) as if you had called IntentSender.sendIntent on it.

Parameters
`intent`	`IntentSender`: The IntentSender to launch.
`fillInIntent`	`Intent`: If non-null, this will be provided as the intent parameter to `IntentSender.sendIntent`.
`flagsMask`	`int`: Intent flags in the original IntentSender that you would like to change. Value is either `0` or a combination of `Intent.FLAG_FROM_BACKGROUND`, `Intent.FLAG_DEBUG_LOG_RESOLUTION`, `Intent.FLAG_EXCLUDE_STOPPED_PACKAGES`, `Intent.FLAG_INCLUDE_STOPPED_PACKAGES`, android.content.Intent.FLAG_DEBUG_TRIAGED_MISSING, android.content.Intent.FLAG_IGNORE_EPHEMERAL, `Intent.FLAG_ACTIVITY_MATCH_EXTERNAL`, `Intent.FLAG_ACTIVITY_NO_HISTORY`, `Intent.FLAG_ACTIVITY_SINGLE_TOP`, `Intent.FLAG_ACTIVITY_NEW_TASK`, `Intent.FLAG_ACTIVITY_MULTIPLE_TASK`, `Intent.FLAG_ACTIVITY_CLEAR_TOP`, `Intent.FLAG_ACTIVITY_FORWARD_RESULT`, `Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP`, `Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS`, `Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT`, `Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED`, `Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY`, `Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET`, `Intent.FLAG_ACTIVITY_NEW_DOCUMENT`, `Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET`, `Intent.FLAG_ACTIVITY_NO_USER_ACTION`, `Intent.FLAG_ACTIVITY_REORDER_TO_FRONT`, `Intent.FLAG_ACTIVITY_NO_ANIMATION`, `Intent.FLAG_ACTIVITY_CLEAR_TASK`, `Intent.FLAG_ACTIVITY_TASK_ON_HOME`, `Intent.FLAG_ACTIVITY_RETAIN_IN_RECENTS`, `Intent.FLAG_ACTIVITY_LAUNCH_ADJACENT`, `Intent.FLAG_RECEIVER_REGISTERED_ONLY`, `Intent.FLAG_RECEIVER_REPLACE_PENDING`, `Intent.FLAG_RECEIVER_FOREGROUND`, `Intent.FLAG_RECEIVER_NO_ABORT`, android.content.Intent.FLAG_RECEIVER_REGISTERED_ONLY_BEFORE_BOOT, android.content.Intent.FLAG_RECEIVER_BOOT_UPGRADE, android.content.Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND, android.content.Intent.FLAG_RECEIVER_EXCLUDE_BACKGROUND, android.content.Intent.FLAG_RECEIVER_FROM_SHELL, `Intent.FLAG_RECEIVER_VISIBLE_TO_INSTANT_APPS`, android.content.Intent.FLAG_RECEIVER_OFFLOAD, and android.content.Intent.FLAG_RECEIVER_OFFLOAD_FOREGROUND

startService

Added in API level 1

public abstract 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 Service.onStartCommand(Intent, int, int) 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 bindService(Intent, BindServiceFlags, Executor, ServiceConnection): it requires the service to remain running until stopService(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 stopService(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 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 bound services for high frequency calls.

Beginning with SDK Version Build.VERSION_CODES.O, apps targeting SDK Version Build.VERSION_CODES.O or higher are not allowed to start background services from the background. See Background Execution Limits 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
`ComponentName`	If the service is being started or is already running, the `ComponentName` of the actual service that was started is returned; else if the service does not exist null is returned.

Throws
`SecurityException`	If the caller does not have permission to access the service or the service can not be found.
`IllegalStateException`	Before Android `Build.VERSION_CODES.S`, if the application is in a state where the service can not be started (such as not in the foreground in a state when services are allowed), `IllegalStateException` was thrown.
`BackgroundServiceStartNotAllowedException`	On Android `Build.VERSION_CODES.S` and later, if the application is in a state where the service can not be started (such as not in the foreground in a state when services are allowed), `BackgroundServiceStartNotAllowedException` is thrown. This exception extends `IllegalStateException`, so apps can use `catch (IllegalStateException)` to catch both.

stopService

Added in API level 1

public abstract boolean stopService (Intent service)

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 stopForeground(STOP_FOREGROUND_DETACH) to decouple the notification from the service's lifecycle before stopping it.

Note that if a stopped service still has ServiceConnection objects bound to it with the BIND_AUTO_CREATE set, it will not be destroyed until all of these bindings are removed. See the Service documentation for more details on a service's lifecycle.

This function will throw SecurityException if you do not have permission to stop the given service.

Parameters
`service`	`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.

Throws
`SecurityException`	If the caller does not have permission to access the service or the service can not be found.
`IllegalStateException`	If the application is in a state where the service can not be started (such as not in the foreground in a state when services are allowed).

unbindService

Added in API level 1

public abstract 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.

bindService(Intent, BindServiceFlags, Executor, ServiceConnection)

unregisterComponentCallbacks

Added in API level 14

public void unregisterComponentCallbacks (ComponentCallbacks callback)

Remove a ComponentCallbacks object that was previously registered with registerComponentCallbacks(android.content.ComponentCallbacks).

Parameters
`callback`	`ComponentCallbacks`

unregisterDeviceIdChangeListener

Added in API level 34

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`: The `Consumer` to remove. This value cannot be `null`.

See also:

unregisterReceiver

Added in API level 1

public abstract 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.

Throws
`IllegalArgumentException`	if the `receiver` was not previously registered or already unregistered.

registerReceiver(BroadcastReceiver, IntentFilter)

updateServiceGroup

Added in API level 29

public void updateServiceGroup (ServiceConnection conn, 
                int group, 
                int importance)

For a service previously bound with bindService(Intent, BindServiceFlags, Executor, 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 bindIsolatedService(Intent, BindServiceFlags, String, Executor, 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.
