```
public class PlayerNotificationManager
extends Object
```
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(Player) 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.
  - Corresponding setter: setUsePlayPauseActions(boolean)
  - Default: true
- useRewindAction - Sets whether the rewind action is used.
  - Corresponding setter: setUseRewindAction(boolean)
  - Default: true
- useRewindActionInCompactView - If useRewindAction is true, sets whether the rewind action is also used in compact view (including the lock screen notification). Else does nothing.
  - Corresponding setter: setUseRewindActionInCompactView(boolean)
  - Default: false
- useFastForwardAction - Sets whether the fast forward action is used.
  - Corresponding setter: setUseFastForwardAction(boolean)
  - Default: true
- 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.
  - Corresponding setter: setUseFastForwardActionInCompactView(boolean)
  - Default: false
- usePreviousAction - Whether the previous action is used.
  - Corresponding setter: setUsePreviousAction(boolean)
  - Default: true
- usePreviousActionInCompactView - If usePreviousAction is true, sets whether the previous action is also used in compact view (including the lock screen notification). Else does nothing.
  - Corresponding setter: setUsePreviousActionInCompactView(boolean)
  - Default: false
- useNextAction - Whether the next action is used.
  - Corresponding setter: setUseNextAction(boolean)
  - Default: true
- useNextActionInCompactView - If useNextAction is true, sets whether the next action is also used in compact view (including the lock screen notification). Else does nothing.
  - Corresponding setter: setUseNextActionInCompactView(boolean)
  - Default: false
- useStopAction - Sets whether the stop action is used.
  - Corresponding setter: setUseStopAction(boolean)
  - Default: false
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 NotificationCompat.Builder.setSmallIcon(int). A different icon can also be specified programmatically by calling setSmallIcon(int).
- 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 programatically by using the PlayerNotificationManager.Builder.
Unlike the drawables above, the large icon (i.e. the icon passed to NotificationCompat.Builder.setLargeIcon(Bitmap) cannot be overridden in this way. Instead, the large icon is obtained from the PlayerNotificationManager.MediaDescriptionAdapter passed to Builder(Context, int, String, MediaDescriptionAdapter).

    Parameters:
    
    player - The player for which state to build a notification.
    
    builder - The builder used to build the last notification, or null. Re-using the builder when possible can prevent notification flicker when Util#SDK_INT < 21.

    Returns:

    This method can be safely overridden. However, the names must be of the playback actions ACTION_PAUSE, ACTION_PLAY, ACTION_FAST_FORWARD, ACTION_REWIND, ACTION_NEXT or ACTION_PREVIOUS, or a key contained in the map returned by PlayerNotificationManager.CustomActionReceiver.createCustomActions(Context, int). Otherwise the action name is ignored.
