title: Send notification when inviting to multiplayer game (Game Services)
body: <p>I’m playing around with Google Play Game Services and multiplayer support. If I invite a player with this service, is it possible to send a notification to the receiver automatically? When I use the demo project nothing like this occurs. The <a href="https://developers.google.com/games/services/android/multiplayer#at_player_sign-in" rel="nofollow noreferrer">documentation</a> however says:</p>
  
  <blockquote>
    <p>If the signed-in player accepts an invitation from the notification area on the Android status bar, your app should accept the invitation and go directly to the game screen (skipping the main menu). </p>
  </blockquote>
  
  <p>This doesn’t explicit says that notifications are supported, but it gives my some hope at least :-). According to this question: <a href="https://stackoverflow.com/questions/16879068/google-play-game-services-invitations-get-lost">Google play game services invitations get lost</a> notifications seems to be supported, but I have never received any. </p>
