I am currently working on a turn based multi player game and using Google Play Game Service for this. All set up has been made. Users can login properly and and select the players to compete with. After the selection when user presses Play button nothing special happens. onActivityResult shows that list of invitees has been prepared and match is created too on the defined criteria. I checked via logs. But on the invitee phone I never got any invitation. I checked on emulator (GenyMotion which serves Google Play Services compared to default emulator of Android SDk) and 2 different Android phones but unable to receive the invitation. I have setup as suggested here
https://developers.google.com/games/services/android/turnbasedMultiplayer
Below is my Code. Kindly anybody look into it and let me know where the problem is.
(P.S. I also came to know Invitations are sent via Google Cloud Messaging and I enabled this service for the game in Developer Console)
