Crash when using Google Play Game Services (Unity3d in Android)

Question

I have a problem. I am developing a game in Unity3d which uses the official Facebook SDK and NerdGPG for Google Play Game Services. However, there is an annoying bug:

WHen I want to see the Achievements or Leaderboards, it opnes the UI, but AFTER I CLOSE the UI, then the game crashes. The Logcat tells the following:

03-05 00:09:54.325: E/AndroidRuntime(10810): Caused by: java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=9002, result=0, data=null} to activity {com.radioactivewasp.flyingwasp/com.facebook.unity.FBUnityPlayerActivity}: java.lang.NullPointerException

Anybody know what could be the solution?

看起来您的Facebook插件Activity在使用RC_UNUSED（9002）requestID时不知道如何处理onActivityResult（）回调，因此我想您将要修改Facebook Player活动，以便NerdGPG插件可以处理该回调。
