/**
* Denotes a {@link android.content.Context} that can be used to create UI, meaning that it can
* provide a {@link android.view.Display} via {@link android.content.Context#getDisplay} and can be
* used to obtain a {@link android.view.WindowManager}, {@link android.view.LayoutInflater} or
* {@link android.app.WallpaperManager} via
* {@link android.content.Context#getSystemService(String)}. A {@link android.content.Context}
* which is marked as {@link UiContext} implies that the {@link android.content.Context} is also a
* {@link android.view.DisplayContext}.
*
* This kind of {@link android.content.Context} is usually an {@link android.app.Activity} or
* created via {@link android.content.Context#createWindowContext(int, android.os.Bundle)}.
*
* This is a marker annotation and has no specific attributes.
