title: OAuth token with Google Play Game Services
body: <p>Is there a way to get the token that was used to log in the user with Google Play Game Services?</p>
  
  <p>I'm looking for something like:</p>
  
  <pre><code>@Override
  public void onSignInSucceeded() {
      String email = getGamesClient().getCurrentAccountName();
      String token = getGamesClient().getToken();
  }
  </code></pre>
  
  <p>I need this to authenticate the user when they are contacting my own server.</p>
