Answer 1

It is undocumented, but you MUST add an intent (using setAction method) to the LiveCard otherwise it won't be displayed...which you are doing...so it's not that.

Are you 100% sure that onStartCommand is being called and your logic is working to reach the code that should setup and display the LiveCard? Get methodical and put some logging in, perhaps.
