title: google real-time multiplayer api example: ButtonClicker
body: <p>i have been really wanting to create a real-time multiplayer android game and was following this tutorial:
  <a href="https://developers.google.com/games/services/android/realtimeMultiplayer" rel="nofollow">https://developers.google.com/games/services/android/realtimeMultiplayer</a></p>
  
  <p>I even corrected the errors on the ButtonClicker example(it's the only one with real-time multiplayer) and got it to work, but didn´t test the multiplayer yet. I copied the whole project to my brother´s computer and he tried to play with me. But every time he click on the button to invite me, it´s saying "the project is incorrectly configured". Does he have to generate another aplication id? has anyone tested the example using 2 different computers and the android emulator of eclipse?</p>
