You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\n\n`\npublic\nstatic\n\n\ninterface\nMediaSessionCompat.OnActiveChangeListener\n`\n\n\n`\n\n\n`\n\n|----------------------------------------------------------------------------|\n| android.support.v4.media.session.MediaSessionCompat.OnActiveChangeListener |\n\n\u003cbr /\u003e\n\n*** ** * ** ***\n\nSummary\n-------\n\n| ### Public methods ||\n|------------------|------------------------------------------------------------------------------------------------------------------------------------|\n| ` abstract void` | ` `[onActiveChanged](/reference/android/support/v4/media/session/MediaSessionCompat.OnActiveChangeListener#onActiveChanged())`() ` |\n\nPublic methods\n--------------\n\n### onActiveChanged\n\nadded in [version 22.1.0](/topic/libraries/support-library/revisions) \n\n```\nvoid onActiveChanged ()\n```\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\n-\n\n Interfaces\n ----------\n\n - [MediaSessionCompat.OnActiveChangeListener](/reference/android/support/v4/media/session/MediaSessionCompat.OnActiveChangeListener)\n-\n\n Classes\n -------\n\n - [MediaButtonReceiver](/reference/android/support/v4/media/session/MediaButtonReceiver)\n - [MediaControllerCompat](/reference/android/support/v4/media/session/MediaControllerCompat)\n - [MediaControllerCompat.Callback](/reference/android/support/v4/media/session/MediaControllerCompat.Callback)\n - [MediaControllerCompat.PlaybackInfo](/reference/android/support/v4/media/session/MediaControllerCompat.PlaybackInfo)\n - [MediaControllerCompat.TransportControls](/reference/android/support/v4/media/session/MediaControllerCompat.TransportControls)\n - [MediaSessionCompat](/reference/android/support/v4/media/session/MediaSessionCompat)\n - [MediaSessionCompat.Callback](/reference/android/support/v4/media/session/MediaSessionCompat.Callback)\n - [MediaSessionCompat.QueueItem](/reference/android/support/v4/media/session/MediaSessionCompat.QueueItem)\n - [MediaSessionCompat.Token](/reference/android/support/v4/media/session/MediaSessionCompat.Token)\n - [ParcelableVolumeInfo](/reference/android/support/v4/media/session/ParcelableVolumeInfo)\n - [PlaybackStateCompat](/reference/android/support/v4/media/session/PlaybackStateCompat)\n - [PlaybackStateCompat.Builder](/reference/android/support/v4/media/session/PlaybackStateCompat.Builder)\n - [PlaybackStateCompat.CustomAction](/reference/android/support/v4/media/session/PlaybackStateCompat.CustomAction)\n - [PlaybackStateCompat.CustomAction.Builder](/reference/android/support/v4/media/session/PlaybackStateCompat.CustomAction.Builder)"]]
