WindowInfoController

fun getInstance(context: @UiContext Context): WindowInfoController

Gets an instance of WindowInfoController for the given Context.

@MainThread
abstract fun requestVisualState(
    context: @UiContext Context,
    request: VisualStateRequest
): Unit

Dispatches a request to modify the visual state of the window.

The requested state is evaluated against the task hierarchy by the system. It is automatically cleared when the requesting task is no longer active.

Note that this is a request; it is up to the system to determine whether the requested visual state will be respected based on device policies and hardware capabilities. Applications should observe WindowLayoutInfo.engagementModes to observe the actual applied state.

Note: Throws IllegalStateException if not called on the main thread, or if the provided context is not a UI context (e.g. an Application context).

On Android 16 (API level 37) and above, this request is forwarded to the system. On lower API levels, calling this method is a no-op.
