open fun clearWallpaper(): Unit

createConfigurationContext

Added in API level 17
open fun createConfigurationContext(overrideConfiguration: Configuration): Context!
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. This value cannot be null.
Return
Context! A Context with the given configuration override.

createDeviceContext

Added in API level 34
open fun createDeviceContext(deviceId: Int): Context

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.
Return
Context This value cannot be null.
Exceptions
java.lang.IllegalArgumentException if the given device ID is not a valid ID of the default device or a virtual device.

Return
Context! A context for the display.

createPackageContext

Added in API level 1
open fun createPackageContext(
    packageName: String!,
    flags: Int
): Context!
Parameters
packageName String!: Name of the application's package.
flags Int: Option flags. Value is either 0 or a combination of android.content.Context#CONTEXT_INCLUDE_CODE, android.content.Context#CONTEXT_IGNORE_SECURITY, android.content.Context#CONTEXT_RESTRICTED, android.content.Context.CONTEXT_DEVICE_PROTECTED_STORAGE, android.content.Context.CONTEXT_CREDENTIAL_PROTECTED_STORAGE, and android.content.Context.CONTEXT_REGISTER_PACKAGE
Return
Context! A Context for the application.
Exceptions
java.lang.SecurityException  
android.content.pm.PackageManager.NameNotFoundException if there is no application with the given package name.

createWindowContext

Added in API level 30
open fun createWindowContext(
    type: Int,
    options: Bundle?
): Context

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 android.view.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 android.view.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. Note that window context only propagate ComponentCallbacks#onConfigurationChanged(Configuration) callback. ComponentCallbacks#onLowMemory() or other callbacks in ComponentCallbacks2 won't be invoked.

Note that using android.app.Application or android.app.Service context for UI-related queries may result in layout or continuity issues on devices with variable screen sizes (e.g. foldables) or in multi-window modes, since these non-UI contexts may not reflect the Configuration changes for the visual container.

type Int: Window type in WindowManager.LayoutParams Value is android.view.WindowManager.LayoutParams#TYPE_BASE_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_STARTING, android.view.WindowManager.LayoutParams#TYPE_DRAWN_APPLICATION, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_PANEL, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_MEDIA, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_SUB_PANEL, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_ATTACHED_DIALOG, android.view.WindowManager.LayoutParams.TYPE_APPLICATION_MEDIA_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_APPLICATION_ABOVE_SUB_PANEL, android.view.WindowManager.LayoutParams#TYPE_STATUS_BAR, android.view.WindowManager.LayoutParams#TYPE_SEARCH_BAR, android.view.WindowManager.LayoutParams#TYPE_PHONE, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_ALERT, android.view.WindowManager.LayoutParams.TYPE_KEYGUARD, android.view.WindowManager.LayoutParams#TYPE_TOAST, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_OVERLAY, android.view.WindowManager.LayoutParams#TYPE_PRIORITY_PHONE, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_DIALOG, android.view.WindowManager.LayoutParams#TYPE_KEYGUARD_DIALOG, android.view.WindowManager.LayoutParams#TYPE_SYSTEM_ERROR, android.view.WindowManager.LayoutParams#TYPE_INPUT_METHOD, android.view.WindowManager.LayoutParams#TYPE_INPUT_METHOD_DIALOG, android.view.WindowManager.LayoutParams#TYPE_WALLPAPER, android.view.WindowManager.LayoutParams.TYPE_STATUS_BAR_PANEL, android.view.WindowManager.LayoutParams.TYPE_SECURE_SYSTEM_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_DRAG, android.view.WindowManager.LayoutParams.TYPE_STATUS_BAR_SUB_PANEL, android.view.WindowManager.LayoutParams.TYPE_POINTER, android.view.WindowManager.LayoutParams.TYPE_NAVIGATION_BAR, android.view.WindowManager.LayoutParams.TYPE_VOLUME_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_BOOT_PROGRESS, android.view.WindowManager.LayoutParams.TYPE_INPUT_CONSUMER, android.view.WindowManager.LayoutParams.TYPE_NAVIGATION_BAR_PANEL, android.view.WindowManager.LayoutParams.TYPE_DISPLAY_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_MAGNIFICATION_OVERLAY, android.view.WindowManager.LayoutParams#TYPE_PRIVATE_PRESENTATION, android.view.WindowManager.LayoutParams.TYPE_VOICE_INTERACTION, android.view.WindowManager.LayoutParams#TYPE_ACCESSIBILITY_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_VOICE_INTERACTION_STARTING, android.view.WindowManager.LayoutParams.TYPE_DOCK_DIVIDER, android.view.WindowManager.LayoutParams.TYPE_QS_DIALOG, android.view.WindowManager.LayoutParams.TYPE_SCREENSHOT, android.view.WindowManager.LayoutParams.TYPE_PRESENTATION, android.view.WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_ACCESSIBILITY_MAGNIFICATION_OVERLAY, android.view.WindowManager.LayoutParams.TYPE_NOTIFICATION_SHADE, or android.view.WindowManager.LayoutParams.TYPE_STATUS_BAR_ADDITIONAL

startService

Added in API level 1
open fun startService(service: Intent!): ComponentName?
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.
Return
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.
Exceptions
java.lang.SecurityException If the caller does not have permission to access the service or the service can not be found.
java.lang.IllegalStateException Before Android android.os.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.
android.app.BackgroundServiceStartNotAllowedException On Android android.os.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), android.app.BackgroundServiceStartNotAllowedException is thrown This excemption extends IllegalStateException, so apps can use catch (IllegalStateException) to catch both.

stopService

Added in API level 1
open fun stopService(service: Intent!): Boolean
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.
Return
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.
Exceptions
java.lang.SecurityException If the caller does not have permission to access the service or the service can not be found.
java.lang.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
open fun unbindService(conn: ServiceConnection): Unit
Parameters
conn ServiceConnection: The connection interface previously supplied to bindService(). This parameter must not be null.

unregisterReceiver

Added in API level 1
open fun unregisterReceiver(receiver: BroadcastReceiver!): Unit
Parameters
receiver BroadcastReceiver!: The BroadcastReceiver to unregister.
Exceptions
java.lang.IllegalArgumentException if the receiver was not previously registered or already unregistered.

updateServiceGroup

Added in API level 29
open fun updateServiceGroup(
    conn: ServiceConnection,
    group: Int,
    importance: Int
): Unit
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.
