tonihei 6f2e24915d Add @NonNullApi and annotate two packages with it.
This new annotation declares everything as non-null by default and can be
used as a package annotation in package-info.java.

In this change the core lib offline package and the mediasession extension is
annotated that way as initial example usage.

ExoPlayer MediaSession extension

The MediaSession extension mediates between a Player (or ExoPlayer) instance 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.

Getting the extension

The easiest way to use the extension is to add it as a gradle dependency:

implementation 'com.google.android.exoplayer:extension-mediasession:2.X.X'

where 2.X.X is the version, which must match the version of the ExoPlayer library being used.

Alternatively, you can clone the ExoPlayer repository and depend on the module locally. Instructions for doing this can be found in ExoPlayer's top level README.

  • Javadoc: Classes matching com.google.android.exoplayer2.ext.mediasession.* belong to this module.
