    annotation UiContext

Denotes a android.content.Context that can be used to create UI, meaning that it can provide a android.view.Display via android.content.Context.getDisplay and can be used to obtain an instance of a UI-related service, such as android.view.WindowManager, android.view.LayoutInflater or android.app.WallpaperManager via android.content.Context.getSystemService. A android.content.Context which is marked as UiContext implies that the android.content.Context is also a DisplayContext.

This kind of android.content.Context is usually an android.app.Activity or an instance created via android.content.Context.createWindowContext. The android.content.res.Configuration for these types of Context types is correctly adjusted to the visual bounds of your window so it can be used to get the correct values for {link android.view.WindowMetrics} and other UI related queries.

This is a marker annotation and has no specific attributes.
