[BlacksAngel]

Hello,

When the player unlock an achivement the pop to show that achievment has been completed don't show.

Could you please help me

        GamesClient gamesClient = Games.getGamesClient(this, GoogleSignIn.getLastSignedInAccount(this));
        gamesClient.setViewForPopups(this.findViewById(android.R.id.content));
        gamesClient.setGravityForPopups(Gravity.TOP | Gravity.CENTER_HORIZONTAL);

I could not see the achievement unlock popups because I simply did not attach pictures to the achievements in the developer's console. As soon as I attached the plug pictures, everything began to work perfectly.
