Question

When I'm trying to save or load my game with Google Play Games plugin (even if i logged in), logcat shows me this: Tried different ways to save the game, but it shows again and again. Ps achievements and leaderboard works fine.

Here is script where I call save and load process:

     #if UNITY_ANDROID

 using System;
 using System.Collections.Generic;
 //gpg
 using GooglePlayGames;
 using GooglePlayGames.BasicApi;

 //for encoding
 using System.Text;
 //for extra save ui
 using UnityEngine.SocialPlatforms;
 //for text, remove
 using UnityEngine.UI;

     private static SaveManager _instance;
     public static SaveManager Instance{

             }
             return _instance;
         }
     }

Answer 1

I had the same problem and it was because I ticked the minify by R8 removing the tick resolved the issue for me and I tested it again enabling R8 minify just gives me the exact exception you have.

this option is at the end of other settings drop down at player settings also this exception only happens when Developement Build is disabled

Answer 2

Ensure that the function header matches with the Call() or CallStatic() method. If your method accepts any arguments then you must have to create a parameters array and pass it to the Call() method. Else it will through the mentioned error.

Assume that, you have a [ICODE]PrintString[/ICODE] method which accepts two arguments.

public void PrintString(Context context, final String message )
{
    //create/show an android toast, with the message and short duration.
    new Handler(Looper.getMainLooper()).post(new Runnable() {
        @Override
        public void run() {
            Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
        }
    });
}

Then you have to call the method in the Unity app like this,

 public void ShowToast(string msg) {
    if (Application.platform == RuntimePlatform.Android) {
        // Retrieve the UnityPlayer class.
        AndroidJavaClass unityPlayerClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

        // Retrieve the UnityPlayerActivity object ( a.k.a. the current context )
        AndroidJavaObject unityActivity = unityPlayerClass.GetStatic<AndroidJavaObject>("currentActivity");

        // Retrieve the "Bridge" from our native plugin.
        // ! Notice we define the complete package name.             
        AndroidJavaObject alert = new AndroidJavaObject("com.codemaker.mylibrary.Alert");

        // Setup the parameters we want to send to our native plugin.             
        object[] parameters = new object[2];
        parameters[0] = unityActivity;
        parameters[1] = msg;

        // Call PrintString in bridge, with our parameters.
        alert.Call("PrintString", parameters);
    }
}
