Added in API level 1

Public Methods

public boolean bindService (Intent service, ServiceConnection conn, int flags)

Added in API level 1

Connect 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.

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

Note: this method can not 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 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).

Parameters
service Identifies the service to connect to. The Intent may specify either an explicit component name, or a logical description (action, category, etc) to match an IntentFilter published by a service.
conn Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.
flags Operation options for the binding. May be 0, BIND_AUTO_CREATE, BIND_DEBUG_UNBIND, BIND_NOT_FOREGROUND, BIND_ABOVE_CLIENT, BIND_ALLOW_OOM_MANAGEMENT, or BIND_WAIVE_PRIORITY.
Returns
  • If you have successfully bound to the service, true is returned; false is returned if the connection is not made so you will not receive the service object.

public int checkCallingOrSelfPermission (String permission)

Added in API level 1

Determine whether the calling process of an IPC or you have been granted a particular permission. This is the same as checkCallingPermission(String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

Parameters
permission The name of the permission being checked.
Returns

public int checkCallingOrSelfUriPermission (Uri uri, int modeFlags)

Added in API level 1

Determine whether the calling process of an IPC or you has been granted permission to access a specific URI. This is the same as checkCallingUriPermission(Uri, int), except it grants your own permissions if you are not currently processing an IPC. Use with care!

Parameters
uri The uri that is being checked.
modeFlags The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
Returns

public int checkCallingPermission (String permission)

Added in API level 1

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(String, int, int) with the pid and uid returned by getCallingPid() and 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 The name of the permission being checked.
Returns

public int checkCallingUriPermission (Uri uri, int modeFlags)

Added in API level 1

Determine whether the calling process and user ID has been granted permission to access a specific URI. This is basically the same as calling checkUriPermission(Uri, int, int, int) with the pid and uid returned by getCallingPid() and getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail.

Parameters
uri The uri that is being checked.
modeFlags The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
Returns

public int checkPermission (String permission, int pid, int uid)

Added in API level 1

Determine whether the given permission is allowed for a particular process and user ID running in the system.

Parameters
permission The name of the permission being checked.
pid The process ID being checked against. Must be > 0.
uid The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.
Returns

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

Added in API level 1

Determine whether a particular process and user ID 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 The uri that is being checked.
pid The process ID being checked against. Must be > 0.
uid The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.
modeFlags The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
Returns

public int checkUriPermission (Uri uri, String readPermission, String writePermission, int pid, int uid, int modeFlags)

Added in API level 1

Check both a Uri and normal permission. This allows you to perform both checkPermission(String, int, int) and checkUriPermission(Uri, int, int, int) in one call.

Parameters
uri The Uri whose permission is to be checked, or null to not do this check.
readPermission The permission that provides overall read access, or null to not do this check.
writePermission The permission that provides overall write acess, or null to not do this check.
pid The process ID being checked against. Must be > 0.
uid The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.
modeFlags The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
Returns

public void clearWallpaper ()

Added in API level 1

This method is deprecated.
Use WallpaperManager.clear() instead.

This method requires the caller to hold the permission SET_WALLPAPER.

public Context createConfigurationContext (Configuration overrideConfiguration)

Added in API level 17

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 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.
Returns
  • A Context with the given configuration override.

public Context createDisplayContext (Display display)

Added in API level 17

Return a new Context object for the current Context but whose resources are adjusted to match the metrics of the given Display. 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. The returned display Context provides a WindowManager (see getSystemService(String)) that is configured to show windows on the given display. The WindowManager's getDefaultDisplay() method can be used to retrieve the Display from the returned Context.

Parameters
display A Display object specifying the display for whose metrics the Context's resources should be tailored and upon which new windows should be shown.
Returns

public Context createPackageContext (String packageName, int flags)

Added in API level 1

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 Name of the application's package.
flags Option flags, one of CONTEXT_INCLUDE_CODE or CONTEXT_IGNORE_SECURITY.
Returns

Returns
  • true if the file was successfully deleted; else false.

public void enforceCallingOrSelfPermission (String permission, String message)

Added in API level 1

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!

public void enforceCallingPermission (String permission, String message)

Added in API level 1

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(String, int, int, String) with the pid and uid returned by getCallingPid() and 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.

public String[] fileList ()

Added in API level 1

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

Returns
  • Array of strings naming the private files.

public Context getApplicationContext ()

Added in API level 1

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(BroadcastReceiver, 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.

public ApplicationInfo getApplicationInfo ()

Added in API level 4

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

public AssetManager getAssets ()

Added in API level 1

Return an AssetManager instance for your application's package.

public File getCacheDir ()

Added in API level 1

Returns the absolute path to the application specific cache directory on the filesystem. These files will be ones that get deleted first when the device runs low on storage. There is no guarantee when these files will be deleted. Note: you should not rely on the system deleting these files for you; you should always have a reasonable maximum, such as 1 MB, for the amount of space you consume with cache files, and prune those files when exceeding that space.

Returns
  • The path of the directory holding application cache files.

public ClassLoader getClassLoader ()

Added in API level 1

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

public ContentResolver getContentResolver ()

Added in API level 1

Return a ContentResolver instance for your application's package.

public File getDatabasePath (String name)

Added in API level 1

Returns the absolute path on the filesystem where a database created with openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory) is stored.

Parameters
name The name of the database for which you would like to get its path.
Returns
  • An absolute path to the given database.

public File getDir (String name, int mode)

Added in API level 1

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.

Parameters
name Name of the directory to retrieve. This is a directory that is created as part of your application data.
mode Operating mode. Use 0 or MODE_PRIVATE for the default operation, MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE to control permissions.
Returns
  • A File object for the requested directory. The directory will have been created if it does not already exist.

public File getExternalCacheDir ()

Added in API level 8

Returns the absolute path to the directory on the primary external filesystem (that is somewhere on Environment.getExternalStorageDirectory() 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 external storage, and thus may not automatically delete these files. Currently the only time files here will be deleted by the platform is when running on JELLY_BEAN_MR1 or later and Environment.isExternalStorageEmulated() returns true. Note that you should be managing the maximum space you will use for these anyway, just like with getCacheDir().
  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it. See the APIs on Environment for information in the storage state.
  • There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

Starting in 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, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.

Returns
  • The path of the directory holding application cache files on external storage. Returns null if external storage is not currently mounted so it could not ensure the path exists; you will need to call this method again when it is available.

public File[] getExternalCacheDirs ()

Added in API level 19

Returns absolute paths to application-specific directories on all 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:

  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it.
  • There is no security enforced with these files.

External storage devices returned here are considered a permanent part of the device, including both emulated external storage and physical media slots, such as SD cards in a battery compartment. The returned paths do not include transient devices, such as USB flash drives.

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 permissions are required to read or write to the returned paths; they are always accessible to the calling app. Write access outside of these paths on secondary external storage devices is not available.

The first path returned is the same as getExternalCacheDir(). Returned paths may be null if a storage device is unavailable.

public File getExternalFilesDir (String type)

Added in API level 8

Returns the absolute path to the directory on the primary external filesystem (that is somewhere on Environment.getExternalStorageDirectory()) 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:

  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it. See the APIs on Environment for information in the storage state.
  • There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

Starting in 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, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.

Here is an example of typical code to manipulate a file in an application's private 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");
    if (file != null) {
        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");
    if (file != null) {
        return file.exists();
    }
    return false;
}

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 private 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 The type of files directory to return. May be null for the root of the files directory or one of the following Environment constants for a subdirectory: DIRECTORY_MUSIC, DIRECTORY_PODCASTS, DIRECTORY_RINGTONES, DIRECTORY_ALARMS, DIRECTORY_NOTIFICATIONS, DIRECTORY_PICTURES, or DIRECTORY_MOVIES.
Returns
  • The path of the directory holding application files on external storage. Returns null if external storage is not currently mounted so it could not ensure the path exists; you will need to call this method again when it is available.

public File[] getExternalFilesDirs (String type)

Added in API level 19

Returns absolute paths to application-specific directories on all external storage devices where the application can place persistent files it owns. These files are internal to the application, 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:

  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it.
  • There is no security enforced with these files.

External storage devices returned here are considered a permanent part of the device, including both emulated external storage and physical media slots, such as SD cards in a battery compartment. The returned paths do not include transient devices, such as USB flash drives.

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 permissions are required to read or write to the returned paths; they are always accessible to the calling app. Write access outside of these paths on secondary external storage devices is not available.

The first path returned is the same as getExternalFilesDir(String). Returned paths may be null if a storage device is unavailable.

public File getFileStreamPath (String name)

Added in API level 1

Returns the absolute path on the filesystem where a file created with openFileOutput(String, int) is stored.

Parameters
name The name of the file for which you would like to get its path.
Returns
  • An absolute path to the given file.

public File getFilesDir ()

Added in API level 1

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

No permissions are required to read or write to the returned path, since this path is internal storage.

Returns
  • The path of the directory holding application files.

public Looper getMainLooper ()

Added in API level 1

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
  • The main looper.

public File getObbDir ()

Added in API level 11

Return the primary 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:

  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it.
  • There is no security enforced with these files. For example, any application holding WRITE_EXTERNAL_STORAGE can write to these files.

Starting in 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, WRITE_EXTERNAL_STORAGE and/or READ_EXTERNAL_STORAGE are required.

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.

public File[] getObbDirs ()

Added in API level 19

Returns absolute paths to application-specific directories on all external storage devices where the application's OBB files (if there are any) can be found. Note if the application does not have any OBB files, these directories may not exist.

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

  • External files are not always available: they will disappear if the user mounts the external storage on a computer or removes it.
  • There is no security enforced with these files.

No permissions are required to read or write to the returned paths; they are always accessible to the calling app. Write access outside of these paths on secondary external storage devices is not available.

The first path returned is the same as getObbDir(). Returned paths may be null if a storage device is unavailable.

public String getPackageCodePath ()

Return a Resources instance for your application's package.

public SharedPreferences getSharedPreferences (String name, int mode)

Added in API level 1

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.

Parameters
name Desired preferences file. 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 (Editor.commit()).
mode Operating mode. Use 0 or MODE_PRIVATE for the default operation, MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE to control permissions. The bit MODE_MULTI_PROCESS can also be used if multiple processes are mutating the same SharedPreferences file. MODE_MULTI_PROCESS is always on in apps targetting Gingerbread (Android 2.3) and below, and off by default in later versions.
Returns
  • The single SharedPreferences instance that can be used to retrieve and modify the preference values.

public Object getSystemService (String name)

Added in API level 1

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:

Parameters
name The name of the desired service.
Returns
  • The service or null if the name does not exist.

public Resources.Theme getTheme ()

Added in API level 1

Return the Theme object associated with this Context.

public Drawable getWallpaper ()

Added in API level 1

This method is deprecated.
Use WallpaperManager.get() instead.

public int getWallpaperDesiredMinimumHeight ()

Added in API level 1

This method is deprecated.
Use WallpaperManager.getDesiredMinimumHeight() instead.

public int getWallpaperDesiredMinimumWidth ()

Added in API level 1

This method is deprecated.
Use WallpaperManager.getDesiredMinimumWidth() instead.

public void grantUriPermission (String toPackage, Uri uri, int modeFlags)

Added in API level 1

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 The package you would like to allow to access the Uri.
uri The Uri you would like to grant access to.
modeFlags The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

mode Operating mode. Use 0 or MODE_PRIVATE for the default operation, MODE_APPEND to append to an existing file, MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE to control permissions.
Returns

public SQLiteDatabase openOrCreateDatabase (String file, int mode, SQLiteDatabase.CursorFactory factory)

Added in API level 1

Open a new private SQLiteDatabase associated with this Context's application package. Create the database file if it doesn't exist.

Parameters
file The name (unique in the application package) of the database.
mode Operating mode. Use 0 or MODE_PRIVATE for the default operation, MODE_WORLD_READABLE and MODE_WORLD_WRITEABLE to control permissions. Use MODE_ENABLE_WRITE_AHEAD_LOGGING to enable write-ahead logging by default.
factory An optional factory class that is called to instantiate a cursor when query is called.
Returns
  • The contents of a newly created database with the given name.

public SQLiteDatabase openOrCreateDatabase (String file, int mode, SQLiteDatabase.CursorFactory factory, DatabaseErrorHandler errorHandler)

Added in API level 11

public Drawable peekWallpaper ()

Added in API level 1

This method is deprecated.
Use WallpaperManager.peek() instead.

public Intent registerReceiver (BroadcastReceiver receiver, IntentFilter filter)

Added in API level 1

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 as 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 ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the 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.

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 The BroadcastReceiver to handle the broadcast.
filter Selects the Intent broadcasts to be received.
Returns
  • The first sticky intent found that matches filter, or null if there are none.

public Intent registerReceiver (BroadcastReceiver receiver, IntentFilter filter, String broadcastPermission, Handler scheduler)

Added in API level 1

Register to receive intent broadcasts, to run in the context of scheduler. See registerReceiver(BroadcastReceiver, 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.

As of ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the 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.

Parameters
receiver The BroadcastReceiver to handle the broadcast.
filter Selects the Intent broadcasts to be received.
broadcastPermission 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 identifying the thread that will receive the Intent. If null, the main thread of the process will be used.
Returns
  • The first sticky intent found that matches filter, or null if there are none.

public void removeStickyBroadcast (Intent intent)

Added in API level 1

Remove the data previously sent with sendStickyBroadcast(Intent), so that it is as if the sticky broadcast had never happened.

You must hold the BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.

Parameters
intent The Intent that was previously broadcast.

public void removeStickyBroadcastAsUser (Intent intent, UserHandle user)

Added in API level 17

Version of removeStickyBroadcast(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. Using it requires holding the INTERACT_ACROSS_USERS permission.

You must hold the BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.

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

public void revokeUriPermission (Uri uri, int modeFlags)

Added in API level 1

Remove all permissions to access a particular content provider Uri that were previously added with grantUriPermission(String, Uri, int). 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".

Parameters
uri The Uri you would like to revoke access to.
modeFlags The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

public void sendBroadcast (Intent intent)

Added in API level 1

Broadcast the given intent to all interested BroadcastReceivers. 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(Intent, String).

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.

public void sendBroadcast (Intent intent, String receiverPermission)

Added in API level 1

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(Intent, String).

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
receiverPermission (optional) String naming a permission that a receiver must hold in order to receive your broadcast. If null, no permission is required.

Added in API level 17

Version of sendBroadcast(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. Using it requires holding the INTERACT_ACROSS_USERS permission.

Parameters
intent The intent to broadcast
user UserHandle to send the intent to.

public void sendBroadcastAsUser (Intent intent, UserHandle user, String receiverPermission)

Added in API level 17

Version of sendBroadcast(Intent, String) 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. Using it requires holding the INTERACT_ACROSS_USERS permission.

Parameters

Added in API level 1

Version of sendBroadcast(Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its onReceive(Context, Intent) method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling sendOrderedBroadcast(Intent, String).

Like sendBroadcast(Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
receiverPermission String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.
resultReceiver Your own BroadcastReceiver to treat as the final receiver of the broadcast.

initialCode An initial value for the result code. Often Activity.RESULT_OK.
initialData An initial value for the result data. Often null.
initialExtras An initial value for the result extras. Often null.

public void sendOrderedBroadcast (Intent intent, String receiverPermission)

Added in API level 1

Broadcast the given intent to all interested BroadcastReceivers, delivering them one at a time to allow more preferred receivers to consume the broadcast before it is delivered to less preferred receivers. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
receiverPermission (optional) String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.

public void sendOrderedBroadcastAsUser (Intent intent, UserHandle user, String receiverPermission, BroadcastReceiver resultReceiver, Handler scheduler, int initialCode, String initialData, Bundle initialExtras)

Added in API level 17

Version of sendOrderedBroadcast(Intent, String, BroadcastReceiver, Handler, int, String, Bundle) 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. Using it requires holding the INTERACT_ACROSS_USERS permission.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
user UserHandle to send the intent to.
receiverPermission String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.
resultReceiver Your own BroadcastReceiver to treat as the final receiver of the broadcast.
scheduler A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
initialCode An initial value for the result code. Often Activity.RESULT_OK.
initialData An initial value for the result data. Often null.
initialExtras An initial value for the result extras. Often null.

public void sendStickyBroadcast (Intent intent)

Added in API level 1

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

You must hold the BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.

Parameters
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.

public void sendStickyBroadcastAsUser (Intent intent, UserHandle user)

Added in API level 17

Version of sendStickyBroadcast(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. Using it requires holding the INTERACT_ACROSS_USERS permission.

Parameters
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.
user UserHandle to send the intent to.

public void sendStickyOrderedBroadcast (Intent intent, BroadcastReceiver resultReceiver, Handler scheduler, int initialCode, String initialData, Bundle initialExtras)

Added in API level 5

Version of sendStickyBroadcast(Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its onReceive(Context, Intent) method will be called with the result values collected from the other receivers. The broadcast will be serialized in the same way as calling sendOrderedBroadcast(Intent, String).

Like sendBroadcast(Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called. Note that the sticky data stored is only the data you initially supply to the broadcast, not the result of any changes made by the receivers.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
resultReceiver Your own BroadcastReceiver to treat as the final receiver of the broadcast.
scheduler A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
initialCode An initial value for the result code. Often Activity.RESULT_OK.
initialData An initial value for the result data. Often null.
initialExtras An initial value for the result extras. Often null.

public void sendStickyOrderedBroadcastAsUser (Intent intent, UserHandle user, BroadcastReceiver resultReceiver, Handler scheduler, int initialCode, String initialData, Bundle initialExtras)

Added in API level 17

Version of sendStickyOrderedBroadcast(Intent, BroadcastReceiver, Handler, int, String, Bundle) 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. Using it requires holding the INTERACT_ACROSS_USERS permission.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
user UserHandle to send the intent to.
resultReceiver Your own BroadcastReceiver to treat as the final receiver of the broadcast.
scheduler A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
initialCode An initial value for the result code. Often Activity.RESULT_OK.
initialData An initial value for the result data. Often null.
initialExtras An initial value for the result extras. Often null.

public void setTheme (int resid)

Added in API level 1

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 setContentView(View) or inflate(int, ViewGroup)).

Parameters
resid The style resource describing the theme.

public void setWallpaper (Bitmap bitmap)

Added in API level 1

This method is deprecated.
Use WallpaperManager.set() instead.

This method requires the caller to hold the permission SET_WALLPAPER.

Throws
IOException

public void setWallpaper (InputStream data)

Added in API level 1

This method is deprecated.
Use WallpaperManager.set() instead.

This method requires the caller to hold the permission SET_WALLPAPER.

Throws
IOException

public void startActivities (Intent[] intents)

Added in API level 11

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

Parameters
intents An array of Intents to be started.

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

Added in API level 16

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

public void startActivity (Intent intent)

Added in API level 1

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

Parameters
intent The description of the activity to start.

public void startActivity (Intent intent, Bundle options)

Added in API level 16

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 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 The description of the activity to start.
options 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.

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

Added in API level 1

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 Name of the Instrumentation component to be run.
profileFile Optional path to write profiling data as the instrumentation runs, or null for no profiling.
arguments Additional optional arguments to pass to the instrumentation, or null.
Returns
  • true if the instrumentation was successfully started, else false if it could not be found.

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

Added in API level 16

Like startActivity(Intent, 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(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 The IntentSender to launch.
fillInIntent If non-null, this will be provided as the intent parameter to sendIntent(Context, int, Intent, IntentSender.OnFinished, Handler).
flagsMask Intent flags in the original IntentSender that you would like to change.
flagsValues Desired values for any bits set in flagsMask
extraFlags Always set to 0.
options Additional options for how the Activity should be started. See Context.startActivity(Intent, Bundle) for more details. If options have also been supplied by the IntentSender, options given here will override any that conflict with those given by the IntentSender.

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

Added in API level 5
Parameters
intent The IntentSender to launch.
fillInIntent If non-null, this will be provided as the intent parameter to sendIntent(Context, int, Intent, IntentSender.OnFinished, Handler).
flagsMask Intent flags in the original IntentSender that you would like to change.
flagsValues Desired values for any bits set in flagsMask
extraFlags Always set to 0.

public ComponentName startService (Intent service)

Added in API level 1

Request that a given application service be started. The Intent should contain 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 log a warning about this and which of the multiple matching services it finds and uses will be undefined. 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 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, ServiceConnection, int): 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() are not nesting: 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.

Parameters
service Identifies the service to be started. The Intent must be either fully explicit (supplying a component name) or specify a specific package name it is targetted to. Additional values may be included in the Intent extras to supply arguments along with this specific start call.
Returns
  • 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.

public boolean stopService (Intent service)

Added in API level 1

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.

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 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 targetted to.
Returns
  • 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.

public void unbindService (ServiceConnection conn)

Added in API level 1

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 The connection interface previously supplied to bindService(). This parameter must not be null.

public void unregisterReceiver (BroadcastReceiver receiver)

Added in API level 1

Unregister a previously registered BroadcastReceiver. All filters that have been registered for this BroadcastReceiver will be removed.

Parameters
receiver The BroadcastReceiver to unregister.
