MediaControllerCompat

public final class MediaControllerCompat
extends Object

java.lang.Object
   ↳ android.support.v4.media.session.MediaControllerCompat

Allows an app to interact with an ongoing media session. Media buttons and other commands can be sent to the session. A callback may be registered to receive updates from the session, such as metadata and play state changes.

A MediaController can be created if you have a MediaSessionCompat.Token from the session owner.

MediaController objects are thread-safe.

This is a helper for accessing features in MediaSession introduced after API level 4 in a backwards compatible fashion.

If MediaControllerCompat is created with a session token from another process, following methods will not work directly after the creation if the session token is not passed through a MediaBrowserCompat:
