Known direct subclasses
LeanbackPlayerAdapter

Leanback PlayerAdapter implementation for Player.

MediaControllerAdapter

A helper class for implementing a adapter layer for MediaControllerCompat.

MediaPlayerAdapter

This implementation extends the PlayerAdapter with a MediaPlayer.


Base class that wraps underlying media player. The class is used by PlaybackGlue, for example PlaybackTransportControlGlue is bound to a PlayerAdapter. This class is intended to be subclassed, MediaPlayerAdapter is a concrete subclass using android.media.MediaPlayer. ExoPlayer also provides a leanback extension that implements PlayerAdapter.
