MediaBrowserService-memory-leak

Sample app with MediaBrowserService that contains a memory leak Created MediaPlaybackService and MainActivity. I have added leak canary and added AppWatcher.objectWatcher.watch(this) in the onDestroy method. When opening and exiting the app, leak canary finds a leak:
