Unable To Connect MediaBrowserCompat

I followed the Android official documentation on connecting MediaBrowserCompat but it's refused to connect, as a matter of fact neither onConnected(), onConnectionSuspended() or on

Solution 1:

Finally found the source of the problem. I was overriding onBind and returning null.

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

removing the above lines fixed it for me.

Solution 2:

You must implement two methods of MediaBrowserServiceCompat. At least:

@Nullable
@Override
public BrowserRoot onGetRoot(@NonNull String clientPackageName, int clientUid, @Nullable Bundle rootHints) {
    return new BrowserRoot(MEDIA_ID_ROOT, null);
}

@Override
public void onLoadChildren(@NonNull String parentId, @NonNull Result<List<MediaBrowserCompat.MediaItem>> result) {
    result.sendResult(null);
}

Solution 3:

onConnectionFailed() can also be called if you fail to declare the service in the AndroidManifest file. Make sure the intent-filter is also correct. source

<service
          android:name=".media.MusicService"
          android:enabled="true"
          android:exported="true"
          tools:ignore="ExportedService">

            <intent-filter>
                <action android:name="android.media.browse.MediaBrowserService" />
            </intent-filter>
 </service>
