Notification style for media playback notifications.
In the expanded form, bigContentView, up to 5
NotificationCompat.Actions specified with
addAction will
be shown as icon-only pushbuttons, suitable for transport controls. The Bitmap given to
setLargeIcon() will
be treated as album artwork.
Unlike the other styles provided here, MediaStyle can also modify the standard-size
contentView; by providing action indices to
setShowActionsInCompactView(int) you can promote up to 3 actions to be displayed
in the standard view alongside the usual content.
Notifications created with MediaStyle will have their category set to
CATEGORY_TRANSPORT unless you set a different
category using setCategory().
Finally, if you attach a MediaSession.Token using
setMediaSession(MediaSessionCompat.Token), the System UI
can identify this as a notification representing an active media session and respond
accordingly (by showing album artwork in the lockscreen, for example).
To use this style with your Notification, feed it to
setStyle(NotificationCompat.Style) like so:
Developers
Notification noti = new NotificationCompat.Builder()
.setSmallIcon(R.drawable.ic_stat_player)
.setContentTitle("Track title")
.setContentText("Artist - Album")
.setLargeIcon(albumArtBitmap))
.setStyle(new NotificationCompat.MediaStyle()
.setMediaSession(mySession))
.build();

Sets whether a cancel button at the top right should be shown in the notification on platforms before Lollipop.
Prior to Lollipop, there was a bug in the framework which prevented the developer to
make a notification dismissable again after having used the same notification as the
ongoing notification for a foreground service. When the notification was posted by
startForeground(int, Notification), but then the service exited foreground mode
via stopForeground(boolean), without removing the notification, the
notification stayed ongoing, and thus not dismissable.
This is a common scenario for media notifications, as this is exactly the service lifecycle that happens when playing/pausing media. Thus, a workaround is provided by the support library: Instead of making the notification ongoing depending on the playback state, the support library provides the ability to add an explicit cancel button to the notification.
Note that the notification is enforced to be ongoing if a cancel button is shown to provide a consistent user experience.
Also note that this method is a no-op when running on Lollipop and later.
