Since a video app runs its media session and media controller in the same activity, the media session callbacks are different from the implementation shown for the audio app server/client architecture. There are no service calls, and notifications are handled via the NotificationManager. The following table shows how the various features are controlled in each callback method:
| onPlay() | onPause() | onStop() | |
| Audio Focus | requestFocus() passing in your OnAudioFocusChangeListener.Always call requestFocus() first, proceed only if focus is granted.
