Unity 5 - Google Play NO Authentication

Questions & Answers
1

Hi UnityAnswers,

I’ve did quite a bit of research into this and can’t find a solution that works for me. I’ve had Google Play Services working in my current game (logging in + leaderboards). However, with the recent addition of AdMob into my project, the app doesn’t log the player in.

I did some quick debugging, and it appears that it’s neither succeeding or failing. It just seems to hang.

Here is my simple code:

void Start()
        {
            PlayGamesPlatform.Activate();
            Social.localUser.Authenticate(ProcessAuthentication);
        }

   void Login()
    {
        Social.localUser.Authenticate(ProcessAuthentication);
    }

    public void LoadLeaderboard()
    {
        if (Social.localUser.authenticated)
        {
            ((PlayGamesPlatform)Social.Active).ShowLeaderboardUI(boardID);
        }
        else
        {
            Login();
        }
    }

Here is my logcat from when I press the leaderboard button. I know this is after the initial auto-attempt at signing in, but because it doesn’t authenticate, the button will attempt to sign in again:

Thanks for any help! It’s just so frustrating, having released two mobile games in the past and now running into these really weird problems … >.>

Delete all files related with Google Play Games (more or less the folders below) and then reinstall Google Play Games plugin and perform it’s configuration (via Unity’s main menu), it should help

/Assets/GooglePlayGames
/Assets/Plugin/Android/libs
