I am trying GCM from this thread https://www.b4x.com/android/forum/threads/b4x-push-server.48560/
but my device never receives GCM push .
Registration is successful and B4J server logs and print to html page that message have been sent to device or devices but B4A client does receives nothing .
I even tried the example and changed server ip and sender Id but I never got it working .
