Google Play Service Leadrboard Error using Unity 2018 (java.lang.ClassNotFoundException: com.google.games.bridge.TokenFragment)

I want to implement a Leaderboard in my Android Mobile App using Unity.

I am using:

Google Play Services are being activated successfully (In-App-Purchases work perfect), but I keep getting this error when trying to get the leaderboard feature working:

java.lang.ClassNotFoundException: com.google.games.bridge.TokenFragment

Further (To make it clear: I replaced the app name with XXXX):

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.games.bridge.TokenFragment" on path: DexPathList[[zip file "/data/app/com.NGDD.XXXX-1/base.apk"],nativeLibraryDirectories=[/data/app/com.NGDD.XXXX-1/lib/arm, /data/app/com.NGDD.XXXX

and

2019-01-01 17:48:52.784 15145-15145/com.NGDD.XXXX W/System: ClassLoader referenced unknown path: /system/framework/QPerformance.jar

...and this leads to:

*** [Play Games Plugin DLL] 01/01/19 17:51:50 +01:00 ERROR: ShowLeaderboardUI can only be called after authentication.

I tried to check the SHA-1 Certificate but didn't know how to check and match Keystore and SHA-1 from Google Play Console on Mac.

This is the Code that is being executed when the scene loads in Unity:

void ActivateGooglePlayServices()
{
    PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().RequestIdToken().Build();
    PlayGamesPlatform.InitializeInstance(config);
    PlayGamesPlatform.Activate();
    LoginToGooglePlay();

}

public void LoginToGooglePlay()
{
    ((PlayGamesPlatform)Social.Active).localUser.Authenticate((bool success) =>
    {
        if (success)
        {
            Debug.Log("!!! Login Success !!!");
        }
        else
        {
            Debug.Log("!!! login failed !!! ");
        }
    });
}

The Leaderboard invoke looks like this:

public void ShowLeaderBoard()
{
    // this didn't work at all: --> ((PlayGamesPlatform)Social.Active).ShowLeaderboardUI (leaderboard_ID);
    // The following line throws: *** [Play Games Plugin DLL] 01/01/19 17:51:50 +01:00 ERROR: ShowLeaderboardUI can only be called after authentication.
    Social.ShowLeaderboardUI();

}

The whole part with the error with a NullReferenceException I cannot understand:

The expected result would be the Google leaderboard UI popping up when calling ShowLeaderBoard().

Solution

  • I had the same issue for days and just figured it out.

    If you have a special character in your project path name then it will not resolve.

    My project had a folder with the "!" in the path name, I simply renamed the folder and made sure not to use spaces or special characters and it works now!

    I hope this fixes your issue too!
