PlayerNotificationManager (ExoPlayer library)

java.lang.Object
- com.google.android.exoplayer2.ui.PlayerNotificationManager

```
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
- rewindIncrementMs - Sets the rewind increment. If set to zero the rewind action is not used.
  - Corresponding setter: setControlDispatcher(ControlDispatcher)
  - Default: DefaultControlDispatcher.DEFAULT_REWIND_MS (5000)
- fastForwardIncrementMs - Sets the fast forward increment. If set to zero the fast forward action is not used.
  - Corresponding setter: setControlDispatcher(ControlDispatcher)
  - Default: DefaultControlDispatcher.DEFAULT_FAST_FORWARD_MS (15000)
- 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.
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 injected when creating the PlayerNotificationManager.

```
    Creates a notification manager and a low-priority notification channel with the specified channelId and channelName.
    If the player notification manager is intended to be used within a foreground service, createWithNotificationChannel(Context, String, int, int, MediaDescriptionAdapter, NotificationListener) should be used to which a PlayerNotificationManager.NotificationListener can be passed. This way you'll receive the notification to put the service into the foreground by calling Service.startForeground(int, Notification).
    
    Parameters:
    
    context - The Context.
    
    channelId - The id of the notification channel.
    
    channelName - A string resource identifier for the user visible name of the notification channel. The recommended maximum length is 40 characters. The string may be truncated if it's too long.
    
    channelDescription - A string resource identifier for the user visible description of the notification channel, or 0 if no description is provided. The recommended maximum length is 300 characters. The value may be truncated if it is too long.
    
    notificationId - The id of the notification.
    
    mediaDescriptionAdapter - The PlayerNotificationManager.MediaDescriptionAdapter.

```
    Creates a notification manager and a low-priority notification channel with the specified channelId and channelName. The PlayerNotificationManager.NotificationListener passed as the last parameter will be notified when the notification is created and cancelled.
    
    Parameters:
    
    context - The Context.
    
    channelId - The id of the notification channel.
    
    channelName - A string resource identifier for the user visible name of the channel. The recommended maximum length is 40 characters. The string may be truncated if it's too long.
    
    channelDescription - A string resource identifier for the user visible description of the channel, or 0 if no description is provided.
    
    notificationId - The id of the notification.
    
    mediaDescriptionAdapter - The PlayerNotificationManager.MediaDescriptionAdapter.
    
    notificationListener - The PlayerNotificationManager.NotificationListener.
  - setPlayer
```
public final void setPlayer(@Nullable
                            Player player)
```
    Sets the Player.
    Setting the player starts a notification immediately unless the player is in Player.STATE_IDLE, in which case the notification is started as soon as the player transitions away from being idle.
    If the player is released it must be removed from the manager by calling setPlayer(null). This will cancel the notification.
    
    Parameters:
    
    player - The Player to use, or null to remove the current player. Only players which are accessed on the main thread are supported (player.getApplicationLooper() == Looper.getMainLooper()).
  - setPlaybackPreparer

```
    Deprecated.
    Use setControlDispatcher(ControlDispatcher) instead. The manager calls ControlDispatcher.dispatchPrepare(Player) instead of PlaybackPreparer.preparePlayback(). The DefaultControlDispatcher that this manager uses by default, calls Player.prepare(). If you wish to intercept or customize this behaviour, you can provide a custom implementation of ControlDispatcher.dispatchPrepare(Player) and pass it to setControlDispatcher(ControlDispatcher).
  - setControlDispatcher

                                                                          Bitmap largeIcon)
```
    Creates the notification given the current player state.
    
    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.
    
    ongoing - Whether the notification should be ongoing.
    
    largeIcon - The large icon to be used.
    
    Returns:
    
    The NotificationCompat.Builder on which to call NotificationCompat.Builder.build() to obtain the notification, or null if no notification should be displayed.
  - getActions
```
protected List<String> getActions(Player player)
```
    Gets the names and order of the actions to be included in the notification at the current player state.
    The playback and custom actions are combined and placed in the following order if not omitted:
```
   +------------------------------------------------------------------------+
   | prev | << | play/pause | >> | next | custom actions | stop |
   +------------------------------------------------------------------------+
 
```
    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.
  - getActionIndicesForCompactView
```
protected int[] getActionIndicesForCompactView(List<String> actionNames,

```
    Gets an array with the indices of the buttons to be shown in compact mode.
    This method can be overridden. The indices must refer to the list of actions passed as the first parameter.
    
    Parameters:
    
    actionNames - The names of the actions included in the notification.
    
    player - The player for which a notification is being built.
