Google Play Service - LogIn Prompt not showing up

Hi Guys

I’ve tried to implement the GPGS into an existing Application. The app is uploaded to the Google Play Store and the status is set to Alpha Test. I have imported the Minimal Demo, which is trying to sign in a user.

When I execute the function:

Social.localUser.Authenticate((bool success) =>
{
     mWaitingForAuth = false;
     if (success)
     {
           mStatusText = "Welcome " + Social.localUser.userName;
     }
     else {
          mStatusText = "Authentication failed.";
     }
});

no Login Prompt is showing up, neither in the Unity Editor or on my Android Phone.

In the Start() function, I activate the PlayGamesPlattform:

GooglePlayGames.PlayGamesPlatform.Activate();

The logcat gives following error:

My Android Configurations are looking like:

Directory to save con…: Assets

Constants class name: Minimal.GPGSIds

My Ressources are defined and my Web App Client ID is also set.

In the Developer Console, the Game is also created in the Services and linked to my existing Google Play Store Project. The Entry is also publicated and there are no errors.

I hope somebody has an idea what cases these errors.

Thank you for answers! :slight_smile:

Same problem, can you solve this problem ?
