For example: WindowManager.LayoutParams p = new WindowManager.LayoutParams( Instead you need to display a window from a background service. If you want to create a floating window that is visible in front of other applications, you can't use an activity because your activity will stop when another app comes to the foreground, and its window will be hidden or destroyed.
WINDOWMANAGER EXAMPLE WINDOWS
So normally you don't need to worry about windows - you just create an activity and Android will do the rest for you.īut you need to interact with the WindowManager if you want to do something unusual like create floating windows that don't fill the screen. The default window fills the screen, so that your activity's window hides any other activities - the WindowManager will display whichever window is on top.

To start and stop WindowLayoutInfo data collection, you can use a restartable lifecycle-aware coroutine in which the repeatOnLifecycle code block is executed when the lifecycle is at least STARTED and stopped when the lifecycle is STOPPED. WindowManager provides support for collecting WindowLayoutInfo data using Kotlin Flows and Java callbacks. The WindowInfoTracker getOrCreate() method creates an instance of WindowInfoTracker. The interface's windowLayoutInfo() method returns a stream of WindowLayoutInfo data that informs your app about a foldable device’s fold state. The WindowInfoTracker interface in Jetpack WindowManager exposes window layout information. When your app is fold aware, it can adapt its layout to avoid placing important content in the area of folds or hinges and use folds and hinges as natural separators. To make your app fold aware, use the Jetpack WindowManager library, which provides an API surface for foldable device window features such as folds and hinges. Large unfolded displays and unique folded states enable new user experiences on foldable devices.
