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()); 
    }


}

Did you find a solution? – Goby

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()
    );

Thank you for your comment. I tried adding this to my code but it still doesn't generate the mediastyle notification. 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. – Kismet

@Kismet try to set metadata before you create MediaStyle. – Ova

@Kismet try to remove setting METADATA_KEY_ALBUM_ART. As I remember, it didn't work for me. I had to use METADATA_KEY_ALBUM_ART_URI, but it also worked if no album art provided. – Ova

I tried commenting out the "METADATA_KEY_ALBUM_ART" line but didn't work – Kismet

have you got any solution – Tablespoon

Is that explained anywhere in the documentation? – Ibarra

It worked for me, on both (virtual device & physical device)!! But I wonder why before adding the meta data it wasn't working on physical device but was showing on emulator(virtual device). – Yonkers

Answer 2

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

Answer 3

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 4

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.

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());
    
else
{
    ...
}
