## Class MediaSessionPlugin

- java.lang.Object
- - com.castlabs.android.Plugin
  - - com.castlabs.sdk.mediasession.MediaSessionPlugin

-     public final class MediaSessionPlugin
      extends Plugin

  MediaSessionPlugin integrates castLabs Player SDK with AndroidX Media2 session APIs. The plugin needs to be enabled before SDK initialization:

         public class MyApp extends Application {
           @Override
           public void onCreate() {
                super.onCreate();

                PlayerSDK.register(new MediaSessionPlugin());
                PlayerSDK.init(getApplicationContext());
            }
         }

  Registering the plugin does not create Media Session yet and the application will need to explicitly request Media Session by calling `enableMediaSession(PlayerController)`. Media Session is linked to the `PlayerController` and therefore the application has to provide `PlayerController` instance when enabling Media Session. The code below enables Media Session when `PlayerController` is created:

           public class SimplePlaybackDemo extends Activity {
              @Override
              protected void onCreate(Bundle savedInstanceState) {
                      // ...
                PlayerView playerView = (PlayerView) findViewById(R.id.player_view);

                MediaSessionPlugin.enableMediaSession(playerView.getPlayerController());

                // ...
                PlayerConfig playerConfig;
                // playerConfig = ...
                playerController.open(playerConfig);
              }

              @Override
              protected void onResume() {
                          super.onResume();
                          // ...
                          PlayerView playerView = (PlayerView) findViewById(R.id.player_view);

                          MediaSessionPlugin.enableMediaSession(playerView.getPlayerController());
                          playerView.getLifecycleDelegate().resume();
                        }
           }

  Media Session lifecycle follows `PlayerController`'s one and is closed automatically upon `PlayerController.destroy()`. However, it is also possible to close Media Session explicitly:

           // ...
           PlayerView playerView = (PlayerView) findViewById(R.id.player_view);
                 MediaSessionPlugin.disableMediaSession(playerView.getPlayerController());
           // ...
