# MediaSession module The MediaSession module mediates between a `Player` and a [MediaSession][]. It automatically retrieves and implements playback actions and syncs the player state with the state of the media session. The behaviour can be extended to support other playback and custom actions. [MediaSession]: https://developer.android.com/reference/android/support/v4/media/session/MediaSessionCompat.html ## Getting the module The easiest way to get the module is to add it as a gradle dependency: ```gradle implementation 'com.google.android.exoplayer:extension-mediasession:2.X.X' ``` where `2.X.X` is the version, which must match the version of the other media modules being used. Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the [top level README][].
