PlayerNotificationManager

@UnstableApi
public class PlayerNotificationManager

Starts, updates and cancels a media style notification reflecting the player state. The actions included in the notification can be customized along with their drawables, as described below.

The notification is cancelled when null is passed to setPlayer or when the notification is dismissed by the user.

If the player is released it must be removed from the manager by calling setPlayer(null).

Action customization

Playback actions can be included or omitted as follows:
  • usePlayPauseActions - Sets whether the play and pause actions are used.
  • useRewindAction - Sets whether the rewind action is used.
  • useRewindActionInCompactView - If useRewindAction is true, sets whether the rewind action is also used in compact view (including the lock screen notification). Else does nothing.
  • useFastForwardAction - Sets whether the fast forward action is used.
  • useFastForwardActionInCompactView - If useFastForwardAction is true, sets whether the fast forward action is also used in compact view (including the lock screen notification). Else does nothing.
  • usePreviousAction - Whether the previous action is used.
  • usePreviousActionInCompactView - If usePreviousAction is true, sets whether the previous action is also used in compact view (including the lock screen notification). Else does nothing.
  • useNextAction - Whether the next action is used.
  • useNextActionInCompactView - If useNextAction is true, sets whether the next action is also used in compact view (including the lock screen notification). Else does nothing.
  • useStopAction - Sets whether the stop action is used.

Overriding drawables

The drawables used by PlayerNotificationManager can be overridden by drawables with the same names defined in your application. The drawables that can be overridden are:
  • exo_notification_small_icon - The icon passed by default to setSmallIcon. A different icon can also be specified programmatically by calling setSmallIcon.
  • exo_notification_play - The play icon.
  • exo_notification_pause - The pause icon.
  • exo_notification_rewind - The rewind icon.
  • exo_notification_fastforward - The fast forward icon.
  • exo_notification_previous - The previous icon.
  • exo_notification_next - The next icon.
  • exo_notification_stop - The stop icon.

Alternatively, the action icons can be set programmatically by using the Builder.

Unlike the drawables above, the large icon (i.e. the icon passed to setLargeIcon cannot be overridden in this way. Instead, the large icon is obtained from the MediaDescriptionAdapter passed to Builder.

Note: This class would require POST_NOTIFICATIONS permission if used without a media session.
