These guides discuss the MediaCompat APIs, which are no longer updated. We strongly recommend using the Jetpack Media3 library instead.

Media session callbacks
Stay organized with collections Save and categorize content based on your preferences.

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.		`abandonAudioFocus()`
Media Session	`setActive(true)` - Update metadata and state	- Update metadata and state	`setActive(false)` - Update metadata and state
Player Implementation	Start the player	Pause the player	Stop the player
Becoming Noisy	Register your `BroadcastReceiver`	Unregister your `BroadcastReceiver`
Notifications	Show notification	Update notification
