android - Error when trying to open PlayScape Exchange catalog on Android

Question

I'm trying to implement the PlayScape SDK into GameMaker: Studio. I've followed the native Android integration guide and, after some work, got it to build without errors. However, I am getting an error message when I try to open the Playscape Exchange catalog and I'm not sure what it means.

I'm currently using the following code:

package ${YYAndroidPackageName};

import ${YYAndroidPackageName}.RunnerActivity;
import com.yoyogames.runner.RunnerJNILib;
//Some more general imports go here

import com.playscape.exchange.ExchangeManager;

public class GMPlayscape extends ExtensionBase
{
    public void showExchange()
    {
        RunnerActivity.ViewHandler.post( new Runnable()
        {
            public void run() 
            {
                ExchangeManager.getInstance().showCatalog();
            }
        });
    }
}

After calling showExchange() from my own code, I'm getting the following error:

E/AndroidRuntime(17482):  FATAL EXCEPTION: main

After this, the application crashes. What am I doing wrong here?

此问题被确定为 SDK 中的错误。它已在 Playscape 发布工具包 1.15 中得到修复。
