title: Can't see achievement in google play games
body: <p>I'm working on a game which has been published to google play. Now we want to add achievement service to this game.</p>
  
  <p>Following <a href="https://github.com/playgameservices/android-samples" rel="nofollow">google play service samples</a>, everything works fine. I can sign in and unlock the achievement successfully.</p>
  
  <p>But the only thing trouble me is that I can't see the achievements in my device.</p>
  
  <p>First I think it may be because the cache, but after two day, I still can't see it.</p>
  
  <p>The game service's state is <code>ready to test</code>, but I heard from someone else, it is no mater.</p>
  
  <p>So I don't know what I had missed.</p>
  
  <p>Any suggestion is appreciate.</p>
