I think that beside Ankit Gupta answer, you can use MediaSession (API > 21) to add native mediaController view :

notificationBuilder

            .setShowActionsInCompactView(new int[]{playPauseButtonPosition})  // show only play/pause in compact view
            .setMediaSession(mSessionToken))
        .setColor(mNotificationColor)
        .setSmallIcon(R.drawable.ic_notification)
        .setVisibility(Notification.VISIBILITY_PUBLIC)
        .setUsesChronometer(true)
        .setContentIntent(createContentIntent(description)) // Create an intent that would open the UI when user clicks the notification
        .setContentTitle(description.getTitle())
        .setContentText(description.getSubtitle())
        .setLargeIcon(art);
