当尝试对本地用户进行身份验证时，我看到下一个异常发生：

I/Unity   (11264):  [Play Games Plugin DLL] 11/22/14 12:32:38 -05:00 DEBUG: Activating PlayGamesPlatform.

来自 GamesNativeSDK 的错误：

E/GamesNativeSDK(11264): Can't register class com/google/android/gms/games/snapshot/SnapshotContents: an exception occurred.
E/GamesNativeSDK(11264): Could not register one or more required Java classes.

这个错误是什么意思，我该如何解决？

我正在使用Google Play Games plugin for Unity 提供的最新版本：

GooglePlayGamesPlugin-0.9.10.unitypackage

【解决方案1】：

仅供参考，@mrggl 还说：

栈溢出线程中引用的错误大多是由 Google Play 服务客户端库的过时版本。确保您已更新到最新版本，重新运行在 Google Play 游戏中设置 android，然后重试。

以防万一出现错误，see the same issue

【解决方案2】：

https://github.com/playgameservices/play-games-plugin-for-unity/issues/280 部分修复了这个问题。

@mrggl 说：

这可能是因为当前插件有对 libc++_shared.so 的传递依赖 - 就是这样，链接静态地反对标准库可能会解决这个问题。

我在这里提交了一个静态链接的 libgpg 版本： https://github.com/playgameservices/play-games-plugin-for-unity/tree/debug_libgpg/debug。用这些覆盖旧版本的libgpg，看看是否解决问题！
