Mediastyle notifications not working in android 11

Question

My custom mediastyle notification no longer works in Android 11 for my music app. It works fine in Android 10 and previous versions.

Is there any other code I need to add so that it works in Android 11.

I should add that getting rid of the " .setMediaSession(mediaSessionCompat.getSessionToken())) " line gives me a notification, but its not an Oreo notification with the full background color, etc.

Here is my code for creating notifications:

public static final String CHANNEL_ID = "Channel1";

//public static final String ACTION_PREVIOUS = "actionprevious";
public static final String ACTION_PLAY = "actionplay";
public static final String ACTION_EXIT = "actionexit";
//public static final String ACTION_NEXT = "actionnext";

public static Notification notification;

public static void createNotification(Context context, Track track, int playbutton, int exitApp, int pos, int size) {

    if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.O) {

        NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(context); 
        MediaSessionCompat mediaSessionCompat = new MediaSessionCompat(context, "tag"); /

        mediaSessionCompat.setActive(true);

        Bitmap icon = BitmapFactory.decodeResource(context.getResources(),R.drawable.half); 

        Intent intentPlay = new Intent(context, NotificationActionService.class)
                .setAction(ACTION_PLAY);
        PendingIntent pendingIntentPlay = PendingIntent.getBroadcast(context, 0,
                intentPlay, PendingIntent.FLAG_UPDATE_CURRENT);

        Intent intentExit = new Intent(context, NotificationActionService.class)
                .setAction(ACTION_EXIT);
        PendingIntent pendingIntentExit = PendingIntent.getBroadcast(context, 0,
                intentExit, PendingIntent.FLAG_UPDATE_CURRENT);

        exitApp = R.drawable.ic_close_black;

    
        Intent intentOpenApp = new Intent(context, MainActivity.class);
        PendingIntent pendingIntentOpenApp = PendingIntent.getActivity(context,0,
                intentOpenApp, 0);

      

         Notification.MediaStyle style = new Notification.MediaStyle();
        androidx.core.app.NotificationCompat.Builder builder = new androidx.core.app.NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
                //NotificationCompat.Builder builder = new NotificationCompat.Builder( this, NOTIFICATION_CHANNEL_ID );
                .setSmallIcon(R.drawable.ic_audiotrack)
                .setVisibility(androidx.core.app.NotificationCompat.VISIBILITY_PUBLIC) 
                .setLargeIcon(icon)
                .setContentTitle( "TEST" )
                .setContentText(notificationText)
                .setContentIntent(pendingIntentOpenApp) 
                .setShowWhen(false) 
                .setOngoing(true)           .setBadgeIconType(androidx.core.app.NotificationCompat.BADGE_ICON_NONE) 
                .setOnlyAlertOnce(true)
                .addAction(action)
                .addAction(generateAction(R.drawable.ic_close_black, "Exit", ACTION_EXIT))
                .setStyle(new NotificationCompat.MediaStyle()
                        .setShowActionsInCompactView(0,1)
                        .setMediaSession(mediaSession.getSessionToken())); 


        mediaSession.setMetadata
            (new MediaMetadataCompat.Builder()
                .putBitmap(MediaMetadataCompat.METADATA_KEY_ALBUM_ART,icon)
                .putString(MediaMetadata.METADATA_KEY_TITLE, "TEST TITLE")
                .putString(MediaMetadata.METADATA_KEY_ARTIST, "TEST ARTIST")
                .build()
        );



        startForeground(1, builder.build()); 
    }


}

Answer 1

You now need to add metadata to your media session as well:

mediaSessionCompat.setMetadata(
    new MediaMetadataCompat.Builder()
        .putString(MediaMetadata.METADATA_KEY_TITLE, track.getTitle())
        .putString(MediaMetadata.METADATA_KEY_ARTIST, track.getArtist())
        .build()
    );

Answer 2

There is a simple solution to it. Just add these lines after mediaSessionCompat declaration.

 mediaSessionCompat=new MediaSessionCompat(this,"tag");



        mediaSessionCompat.setMetadata(
                new MediaMetadataCompat.Builder()
                .putString(MediaMetadata.METADATA_KEY_TITLE,"Song Title")
                .putString(MediaMetadata.METADATA_KEY_ARTIST,"Artist")
                .build());

Hope this helps.

Answer 3

I had same issue and was able to resolve it only once I set compileSdkVersion to 30.

Answer 4

Just had the same problem. Turns out .setOngoing(true) doesn't seem to work right with Mediastyle notifications. Once I removed it, the notification showed up correctly.

Answer 5

Works for me : Should add "mMediaSession.setMetadata(..)" after setStyle(..)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        ...
            mBuilder.setStyle(new androidx.media.app.NotificationCompat.MediaStyle()
                            .setMediaSession(mMediaSession.getSessionToken())
                            .setShowCancelButton(true)
                            .setShowActionsInCompactView(0, 1, 2)
                            .setCancelButtonIntent(
                                    MediaButtonReceiver.buildMediaButtonPendingIntent(
                                            context, PlaybackStateCompat.ACTION_STOP)))
                            .addAction(new NotificationCompat.Action(
                                    R.drawable.ic_noti_previous, "Previous",
                                    ppreviousIntent))
                            .addAction(new NotificationCompat.Action(
                                    R.drawable.ic_noti_pause, "Pause",
                                    pplayIntent))
                            .addAction(new NotificationCompat.Action(
                                    R.drawable.ic_noti_next, "Next",
                                    pnextIntent))
                            .addAction(new NotificationCompat.Action(
                                    R.drawable.ic_noti_close, "Close",
                                    pcloseIntent));
            mMediaSession.setMetadata(
                new MediaMetadataCompat.Builder()
                    .putString(MediaMetadata.METADATA_KEY_TITLE,"Song Title")
                                    .putString(MediaMetadata.METADATA_KEY_ARTIST,"Artist")
                                    .build());
