title: How to set EXTRA_PAGE and EXTRA_PAGE_SIZE in a MediaBrowserServiceCompat by getting reference to the Android Auto MediaBrowser?
body: <p>I have an Android Auto app. I would like to take advantage of pagination for browsing within the app. It seems that you can set EXTRA_PAGE and EXTRA_PAGE_SIZE by getting a reference to the MediaBrowserCompat and passing those constants in .subscribe(). However, I can't figure out how to get a reference to the MediaBrowserCompat that Android Auto Audio uses in order to call .subscribe().</p>
  
  <p>This seems way too complicated for something that should be simple, am I just overthinking things?</p>
