Can't use Support v4 MediaSession Token with Notification MediaStyle.setMediaSession

I'm working on some Android code, and I wan't to build a MediaStyle Notification. I'm already using AppCompat for most of m mediaplayer and mediasession, and what I don't already use I'm planning on switching over just so I can keep 4.x compatibility.

Issue? Well, I'm trying to make my MediaStyle notification, and give it a MediaSession Token. My support.v4.media.session.MediaSession.Token doesn't seem to be compatable with media.session.MediaSession.Token

I've tried casting, and just leaving it raw. I'm honestly confused because the docs say they're compatible.

If you want the rest of the code, the code can be found here

Or you can look at the relevant code here.

    Intent nIntent = new Intent(context, MainActivity.class);
    PendingIntent pIntent = PendingIntent.getActivity(context, 0, nIntent, 0);

    n.setLatestEventInfo(context, notifTitle, notifMessage, pIntent);

    notificationManager.notify(notifId, n);

    ComponentName c = new ComponentName("com.thefan.android", "BackgroundService");
    ms = new MediaSessionCompat(this, "TheFan", c,  pIntent);
    ms.setMetadata(new MediaMetadataCompat.Builder()
            .putBitmap(MediaMetadataCompat.METADATA_KEY_ALBUM_ART, artwork)
            .putString(MediaMetadataCompat.METADATA_KEY_ARTIST, "Pink Floyd")
            .putString(MediaMetadataCompat.METADATA_KEY_ALBUM, "Dark Side of the Moon")
            .putString(MediaMetadataCompat.METADATA_KEY_TITLE, "The Great Gig in the Sky")
            .build());
    // Indicate you're ready to receive media commands
    ms.setActive(true);
    // Attach a new Callback to receive MediaSession updates
    ms.setCallback(new MediaSessionCompat.Callback() {
        // Implement your callbacks
    });
    // Indicate you want to receive transport controls via your Callback
    ms.setFlags(MediaSession.FLAG_HANDLES_TRANSPORT_CONTROLS);
    // Create a new Notification
    final Notification noti = new Notification.Builder(this)
            // Hide the timestamp
            .setShowWhen(false)
                    // Set the Notification style
            .setStyle(new Notification.MediaStyle()
                    // Attach our MediaSession token
                    .setMediaSession(ms.getSessionToken())
                            // Show our playback controls in the compat view
                    .setShowActionsInCompactView(0, 1, 2))
                    // Set the Notification color
            .setColor(0xFFDB4437)
                    // Set the large and small icons
            .setLargeIcon(artwork)
            .setSmallIcon(R.drawable.your_small_icon)
                    // Set Notification content information
            .setContentText("Pink Floyd")
            .setContentInfo("Dark Side of the Moon")
            .setContentTitle("The Great Gig in the Sky")
                    // Add some playback controls
            .addAction(R.drawable.your_prev_icon, "prev", retreivePlaybackAction(3))
            .addAction(R.drawable.your_pause_icon, "pause", retreivePlaybackAction(1))
            .addAction(R.drawable.your_next_icon, "next", retreivePlaybackAction(2))
            .build();

As others have pointed out, the underlying MediaSession.Token can be obtained through MediaSessionCompat.getToken(), and its type can safely be cast. In Kotlin:

val mediaStyle = Notification.MediaStyle()
    .setMediaSession(mediaSessionCompat.sessionToken.token as MediaSession.Token?)

For whom this may be helpful.

Firstly you need import v4 MediaSessionCompat and comment the general MediaSession like this:

//import android.media.session.MediaSession;
import android.support.v4.media.session.MediaSessionCompat;

In your code, you need use MediaSessonCompat like this:

MediaSessionCompat mediaSession = new MediaSessionCompat(getApplicationContext(), "session tag");

MediaSessionCompat.Token token = mediaSession.getSessionToken();

mediaStyle.setMediaSession(token);

It is posible.

Check your imports, maybe you are importing bad versions.

  • MediaStyle should android.support.v7.app.NotificationCompat.MediaStyle
  • NotificationBuilder should be android.support.v7.app.NotificationCompat.Builder
  • Notification should be compat android.support.v4.app.NotificationCompat

If you are going to support older version than 21 you need to use Compat classes (ALL compat classes instead of "normal" ones).

Magical. There's a Token.getToken(); You need to use that.

Then again, MediaStyle Notifications are only API 21 compatible, so good luck.
