Chrome-cast Sample App doesn't work

Question

I managed to whitelisted my device and I got the AppID and also setup my receiver url. I am able to build and run the CastSample App. I can click the cast button and my TV shows a blank screen. I tried to select one media from the list but nothing is displayed on my TV.

From the log I see the follwoing error some seconds after I clicked the cast button. Am I missing anything?

07-30 20:29:12.895: W/StartSessionTask(19880): Expected a channel but never got a connection service URL

Answer 1

I checked the cast-android-sample on github and find that they have updated the receiver.html to have:

// Initialize and start the media playing receiver
var receiver = new cast.receiver.Receiver(
    'YOUR_APP_ID_HERE', 
    [cast.receiver.RemoteMedia.NAMESPACE],
    "",
    5);

Then I put my AppID there and uploaded the new receiver.html to my server then restarted everything and now I am able to play these sample medias.
