title: GoogleSignIn Works But Google_DEFAULT_GAMES Doesn't
body: <p>When I call GoogleSignInOptions from the default sign-in option, I get a signIn UI displayed</p>
  
  <pre><code>GoogleSignInOptions ClientInfo = GoogleSignInOptions.Builder.(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
  GoogleSignInClient mGoogleSignInClient = GoogleSignInClient.getClient(this, ClientInfo);
  Intent SignInintent = mGoogleSignInClient.getSignInIntent();
  startActivityForResult(SignInintent,3000);
  </code></pre>
  
  <p>However if I call GoogleSignInOptions with the default games sign in. I get no UI displayed at all infact I get a dim light as if it wants to display but then it dissappears.</p>
  
  <pre><code>GoogleSignInOptions ClientInfo = GoogleSignInOptions.Builder. GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN).requestEmail().build();
  GoogleSignInClient mGoogleSignInClient = GoogleSignInClient.getClient(this, ClientInfo);
  Intent SignInintent = mGoogleSignInClient.getSignInIntent();
  startActivityForResult(SignInintent,3000);
  </code></pre>
