Unity Google Play Service Plugin Social.localUser.Authenticate(…) App Crash

Unity3d Code for Google Play Service.I am using GooglePlayGamesPlugin-0.9.36 and Unity 5.4

using UnityEngine;
    using System.Collections;
    using UnityEngine.SocialPlatforms;
    using GooglePlayGames;

public class MainGui : MonoBehaviour
{
    private const float FontSizeMult = 0.05f;
    private bool mWaitingForAuth = false;
    private string mStatusText = "Ready.";
    private bool dumpedToken = false;
void Start()
{
    // Select the Google Play Games platform as our social platform implementation
    PlayGamesPlatform.Activate();
}

void OnGUI()
{
    GUI.skin.button.fontSize = (int)(FontSizeMult * Screen.height);
    GUI.skin.label.fontSize = (int)(FontSizeMult * Screen.height);

    GUI.Label(new Rect(20, 20, Screen.width, Screen.height * 0.25f),
              mStatusText);

    Rect buttonRect = new Rect(0.25f * Screen.width, 0.10f * Screen.height,
                      0.5f * Screen.width, 0.25f * Screen.height);
    Rect imageRect = new Rect(buttonRect.x + buttonRect.width / 4f,
                              buttonRect.y + buttonRect.height * 1.1f,
                              buttonRect.width / 2f, buttonRect.width / 2f);

    if (mWaitingForAuth)
    {
        return;
    }

    string buttonLabel;


    if (Social.localUser.authenticated)
    {
        buttonLabel = "Sign Out";
        if (Social.localUser.image != null)
        {
            GUI.DrawTexture(imageRect, Social.localUser.image,
                            ScaleMode.ScaleToFit);
        }
        else {
            GUI.Label(imageRect, "No image available");
        }

        mStatusText = "Ready";

        if (!dumpedToken)
        {
            string token = GooglePlayGames.PlayGamesPlatform.Instance.GetToken();

            Debug.Log("AccessToken = " + token);
            dumpedToken = token != null && token.Length > 0;
        }
    }
    else {
        buttonLabel = "Authenticate";
    }

    if (GUI.Button(buttonRect, buttonLabel))
    {
        if (!Social.localUser.authenticated)
        {
            // Authenticate
            mWaitingForAuth = true;
            mStatusText = "Authenticating...";
            Social.localUser.Authenticate((bool success) =>
            {
                mWaitingForAuth = false;
                if (success)
                {
                    mStatusText = "Welcome " + Social.localUser.userName;
                }
                else {
                    mStatusText = "Authentication failed.";
                }
            });
        }
        else {
            // Sign out!
            mStatusText = "Signing out.";
            ((GooglePlayGames.PlayGamesPlatform)Social.Active).SignOut();
        }
    }
    }
}

Downgrading the .aar file fix the problem

See: https://github.com/playgameservices/play-games-plugin-for-unity/issues/1604

Older Files: https://drive.google.com/drive/u/0/folders/0B-w9u2zDKrHGUmtjMmk2VDhhSjA

Here is how I worked around this issue:

  1. Go to Assets > Play Services Resolver > Android Resolver > Settings
    Un-tick Enable Background resolution (This will suppress the update notifications once we downgrade the .aar files)

  2. Go to \extras\google\m2repository\com\google\android\gms .Inside each of the folders there are version folders (such as 10.0.1, 10.2.0). And inside those are the .aar files we need or download from above google drive link
    We will need the following files:

  • play-services-ads-10.0.1.aar
  • play-services-ads-lite-10.0.1.aar
  • play-services-auth-10.0.1.aar
  • play-services-auth-base-10.0.1.aar
  • play-services-base-10.0.1.aar
  • play-services-basement-10.0.1.aar
  • play-services-clearcut-10.0.1.aar
  • play-services-drive-10.0.1.aar
  • play-services-games-10.0.1.aar
  • play-services-gass-10.0.1.aar
  • play-services-nearby-10.0.1.aar
  • play-services-tasks-10.0.1.aar
  1. Under \Assets\Plugins\Android delete the 10.2.0 versions of the .aar files above, with their META files.
  2. Copy the 10.0.1 versions over
  3. Build and run your project.
