// Create a media session. NotificationCompat.MediaStyle
// PlayerService is your own Service or Activity responsible for media playback.  
val mediaSession = MediaSessionCompat(this, "PlayerService")

// Create a MediaStyle object and supply your media session token to it. 
val mediaStyle = Notification.MediaStyle().setMediaSession(mediaSession.sessionToken)

// Create a Notification which is styled by your MediaStyle object. 
// This connects your media session to the media controls. 
// Don't forget to include a small icon.
val notification = Notification.Builder(this@PlayerService, CHANNEL_ID)
        .setStyle(mediaStyle)
        .setSmallIcon(R.drawable.ic_app_logo)
        .build()

// Specify any actions which your users can perform, such as pausing and skipping to 
the next track. 
val pauseAction: Notification.Action = Notification.Action.Builder(
        pauseIcon, "Pause", pauseIntent
    ).build()
notification.addAction(pauseAction)
