Invalid application Id - chromecast

Question

I was tweaking the Google Cast code, the one provided here.

I have the whole work space setup done, but, when trying to run the sample app on the Android phone, I get the following error.

I just assigned the package name as the app id. Where do I get the app Id? Should I register with Google for getting an app id? How does it work?

Answer 1

The best way is to create your own receiver (Styled Media Receiver). When you register that, you get an app id; I suggest you go to Cast developers site and familiarize yourself with Chromecast and how it works. After you get an App Id, you need to insert that into res/values/string.xml where YOUR_APP_ID string is.

Answer 2

Remove quotation mark:

- CastMediaControlIntent.categoryForCast("CastMediaControlIntent.DEFAULT_MEDIA_RECEIVER_APPLICATION_ID")
+ CastMediaControlIntent.categoryForCast(CastMediaControlIntent.DEFAULT_MEDIA_RECEIVER_APPLICATION_ID)
