title: cannot find symbol com.google.android.gms.games.snapshot
body: <p>I'm trying to implement "SaveGame" with Google Play Services and I have the following error:</p>
  
  <pre><code>error: cannot find symbol
  import com.google.android.gms.games.snapshot;
                                      ^
  symbol:   class snapshot
  location: package com.google.android.gms.games
  </code></pre>
  
  <p>Anyone knows what can cause this?</p>
  
  <p>Thanks!</p>
