Cannot authenticate on PlayGamesPlatform (java.lang.ClassNotFoundException: com.google.games.bridge.TokenFragment)

[Kendja]

Hi!

• using correct app signing certificate/sha1
• unity 2018.2.14f1
• force resolved multiple times
• i do have \Assets\Plugins\Android\com.android.support.support-fragment-26.1.0.aar

Any ideas how to fix this? Thanks for advance. Trying a second day to find a working solution.

code:

GooglePlayGames.BasicApi.PlayGamesClientConfiguration config = new GooglePlayGames.BasicApi.PlayGamesClientConfiguration.Builder()
        // requests an ID token be generated.  This OAuth token can be used to
        //  identify the player to other services such as Firebase.
        .RequestIdToken()
        .Build();

PlayGamesPlatform.InitializeInstance(config);
// recommended for debugging:
//PlayGamesPlatform.DebugLogEnabled = true;
// Activate the Google Play Games platform
PlayGamesPlatform.Activate();

Social.localUser.Authenticate((bool success) =>
{
    if (success) {
        // if we signed in successfully, load data from cloud
        Debug.Log("Login successful!");
    } else {
        // no need to show error message (error messages are shown automatically
        // by plugin)
        Debug.LogWarning("Failed to sign in with Google Play Games.");
    }
});

Is this a latest plugin version 0.9.57? Is proguard disabled in build?

It worked in 0.9.55 on some devices even with this error which was already present...

Unity 2018.3.0f2, Proguard disabled, build system is Gradle

EDIT: Fixed by pull request.
