title: How to show the welcome popup on play games services?
body: <p>I implement the google play game services on my game. I can connect on it but when I come back to my game, I can't show the welcome POPUP ... How can I show it ? </p>
  
  <p>I tried the setViewForPopups and setGravityForPopups like they said on the documentation...</p>
  
  <pre><code>private void startSignInIntent() {
   GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
              .requestEmail()
              .build();
  GoogleSignInClient signInClient = GoogleSignIn.getClient(getActivity(),
              gso);
      Intent intent = signInClient.getSignInIntent();
      startActivityForResult(intent, RC_SIGN_IN);
  }
  
  
  @Override
  public void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (requestCode == RC_SIGN_IN) {
          GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
          if (result.isSuccess()) {
              // The signed in account is stored in the result.
              GoogleSignInAccount signedInAccount = result.getSignInAccount();
              Games.getGamesClient(getContext(), signedInAccount).setViewForPopups(getView());
          } else {
              String message = result.getStatus().getStatusMessage();
              if (message == null || message.isEmpty()) {
                  message = getString(R.string.signin_other_error);
              }
              new AlertDialog.Builder(getActivity()).setMessage(message)
                      .setNeutralButton(android.R.string.ok, null).show();
          }
      }
  }
  </code></pre>
