title: MediaRouteHelper.buildMediaRouteSelector doesn't show me my chromecast when I send the app name parameter
body: <p>I have a weird situation, My app was working fine and I was able to select my chromecast device and see my receiver application without problem, so my chromecast is whitelisted.</p>
  
  <p>Now my app doesn't work, the chromecast icon is disabled and I can't select my device.</p>
  
  <p>Basically this line was working fine</p>
  
  <p>mMediaRouteSelector = MediaRouteHelper.buildMediaRouteSelector(MediaRouteHelper.CATEGORY_CAST, getResources().getString(R.string.app_name), null);</p>
  
  <p>but now it doesn't. Why? any ideas?</p>
  
  <p>But this line works fine:</p>
  
  <p>MediaRouteHelper.buildMediaRouteSelector( MediaRouteHelper.CATEGORY_CAST)</p>
  
  <p>Of course I can't see the receiver app (html).</p>
  
  <p>I am thinking maybe my chromecast is not whitelisted, just like the beginning when I started with the development.</p>
  
  <p>Any ideas?</p>
  
  <p>Is there a way to check if my chromecast is whitelisted or not?</p>
  
  <p>Thanks in advanced.</p>
