question

Good day! I have a question about GooglePlusLogin.

You example using code for get Google token:

    /// <summary>

    /// Google plus wrapper class was contributed by Hamza Lazâar Twitter: @RealJohnTube

    /// For the purposes of PlayFab authentication, we are only using GetToken(); however, there are many more integrated Google+ features available. 

    /// This class calls a native java plugin which then returns via callback [OnTokenReceivedCallback] to a scene.

    /// </summary>

    /// <param name="callBackObject">This is the name of the gameObject to call back to with the token. (Plugin default = "GooglePlusGO")</param>

    /// <param name="callBackMethod">This is the name of the method to call. (Plugin default = "OnGoogleTokenReceived")</param>

    public static void StartGooglePlusLogin(string callBackObject="Panel_Authentication", string callBackMethod="OnGoogleTokenReceived")

    {

        #if UNITY_ANDROID

        // internal settings for using GooglePlusActivity

        //int SIGN_IN_REASON = 1;

        int GET_TOKEN_REASON = 2;

        //int SIGN_OUT_REASON = 3;

        //int LOAD_CIRCLES_REASON = 4;

        //int REVOKE_ACCESS_REASON = 5;

        //int INVALIDATE_TOKEN_REASON = 6;

        

        string className = "com.ThugLeaf.GooglePlusForUnity.GooglePlusActivity"; //com.ThugLeaf.GooglePlusForUnity.DemoActivity

        AndroidJNI.AttachCurrentThread();

        using( AndroidJavaClass activityClass = new AndroidJavaClass(className))

        {

            //using(AndroidJavaObject activityInstance = activityClass.GetStatic<AndroidJavaObject>("mContext"))

            //{

                activityClass.SetStatic<string>("UnityObjectName", callBackObject); //UnityObjectName

                activityClass.SetStatic<string>("OnTokenReceivedCallback", callBackMethod); //TokenCallbackName

                //activityInstance.Call("GetToken");

                activityClass.CallStatic("Start", new object[] { GET_TOKEN_REASON });

            //}

        }

        #endif

    }

For receive token used callback: "OnTokenReceivedCallback". But if user not choose account or cancel overlay window. Plugin don't call any callback.
How i can receive callback with fail?

Currently, this is not supported with our plugin. To get this you will need to make modifications to the Java source and re-compile the plugin.

A full featured Google API plugin is beyond the scope of what we are supporting, so it is doubtful that any further development will happen on this plugin.

I would suggest that prior to calling the PlayFab API, if you detect any empty fields, then you will want to manually trigger the flow by starting the process again from the beginning.

I have a new solution for this. Please refer to it here.
