如何正确更新 Google Analytics Unity 插件
How to properly update Google Analytics Unity plugin
我有一个安装了 GAv3 的 Android 游戏，如果我将 Google Analytics 更新到版本 4，游戏会开始，但我会遇到一些异常。这是来自 Android 设备监视器的日志：

我试过直接安装插件，让Unity覆盖文件，然后自己删除文件再安装。在这两种情况下，我都会收到这些错误。
将 play-services-analytics-8.4.0.aar 从 {android-sdk}\extras\google\m2repository\com\google\android\gms\play-services-analytics.4.0 复制到您的 Assets/Plugins/Android 文件夹。它适用于此 person，也可能适用于您。
