使用 Google Play 游戏服务时崩溃（Android 中的 Unity3d）

Question

我有问题。我正在 Unity3d 中开发一款游戏，该游戏使用官方 Facebook SDK 和 NerdGPG 用于 Google Play 游戏服务。但是，有一个烦人的错误：

当我想查看成就或排行榜时，它会打开 UI，但在我关闭 UI 后，游戏就会崩溃。 Logcat 告诉以下内容：

有人知道解决办法吗？

Answer 1

当您使用 RC_UNUSED(9002) requestID 时，您的 Facebook 插件 Activity 似乎不知道如何处理 onActivityResult() 回调。所以我想您会想要修改您的 Facebook 播放器活动，以便 NerdGPG 插件处理回调。
