Remarks

The interface that apps use to talk to the window manager.

Each window manager instance is bound to a Display. To obtain the WindowManager associated with a display, call Context#createWindowContext(Display, int, Bundle) to get the display's UI context, then call Context#getSystemService(String) or Context#getSystemService(Class) on the UI context.

The simplest way to show a window on a particular display is to create a Presentation, which automatically obtains a WindowManager and context for the display.

Fields

PropertyActivityEmbeddingAllowSystemOverride	Application-level `android.content.pm.PackageManager.Property PackageManager.Property` tag that specifies whether OEMs are permitted to provide activity embedding split-rule configurations on behalf of the app.
PropertyActivityEmbeddingSplitsEnabled	Application level `android.content.pm.PackageManager.Property PackageManager .Property` that an app can specify to inform the system that the app is ActivityEmbedding split feature enabled.
PropertyCameraCompatAllowForceRotation	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the app should be excluded from the camera compatibility force rotation treatment.
PropertyCameraCompatAllowRefresh	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the app should be excluded from the activity "refresh" after the camera compatibility force rotation treatment.
PropertyCameraCompatEnableRefreshViaPause	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the activity should be or shouldn't be "refreshed" after the camera compatibility force rotation treatment using "paused -> resumed" cycle rather than "stopped -> resumed".
PropertyCompatAllowDisplayOrientationOverride	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the app should be opted-out from the compatibility override that fixes display orientation to landscape natural orientation when an activity is fullscreen.
PropertyCompatAllowOrientationOverride	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the app should be excluded from the compatibility override for orientation set by the device manufacturer.
PropertyCompatAllowSandboxingViewBoundsApis	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that it needs to be opted-out from the compatibility treatment that sandboxes `android.view.View` API.
PropertyCompatEnableFakeFocus	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the application can be opted-in or opted-out from the compatibility treatment that enables sending a fake focus event for unfocused resumed split screen activities.
PropertyCompatIgnoreRequestedOrientation	Application level `android.content.pm.PackageManager.Property PackageManager .Property` for an app to inform the system that the app can be opted-in or opted-out from the compatibility treatment that avoids `android.app.Activity#setRequestedOrientation` loops.

Properties

CurrentWindowMetrics	Returns the `WindowMetrics` according to the current system state.
DefaultDisplay	Returns the Display upon which this IWindowManager instance will create new windows.
Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
IsCrossWindowBlurEnabled	Returns whether cross-window blur is currently enabled.
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
MaximumWindowMetrics	Returns the largest `WindowMetrics` an app may expect in the current system state.
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

AddCrossWindowBlurEnabledListener(IConsumer)	Adds a listener, which will be called when cross-window blurs are enabled/disabled at runtime.
AddCrossWindowBlurEnabledListener(IExecutor, IConsumer)	Adds a listener, which will be called when cross-window blurs are enabled/disabled at runtime.
AddProposedRotationListener(IExecutor, IIntConsumer)	Adds a listener to start monitoring the proposed rotation of the current associated context.
AddView(View, ViewGroup+LayoutParams)	Assign the passed LayoutParams to the passed View and add the view to the window. (Inherited from IViewManager)
Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
RemoveCrossWindowBlurEnabledListener(IConsumer)	Removes a listener, previously added with `#addCrossWindowBlurEnabledListener`
RemoveProposedRotationListener(IIntConsumer)	Removes a listener, previously added with `#addProposedRotationListener`.
RemoveView(View)	(Inherited from IViewManager)
RemoveViewImmediate(View)	Special variation of `#removeView` that immediately invokes the given view hierarchy's `View#onDetachedFromWindow() View.onDetachedFromWindow()` methods before returning.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)
UpdateViewLayout(View, ViewGroup+LayoutParams)	(Inherited from IViewManager)
