【问题讨论】：

我今天早上也将 AS 更新到 2.2.2，我没有遇到任何问题...如果其他人有同样的问题，您是否在 android 问题论坛上搜索过？
不，我会这样做，谢谢。我用不同的项目打开了 5 个 Android Studio 窗口。我的电脑非常强大，所以这不是问题。我感觉这是因为 5 个窗口发生了这种情况
如果您还没有找到解决方案，我建议您在 android 论坛上发布堆栈跟踪，看看 Google 工程师是否可以帮助您...抱歉之前我从未见过此错误：（。可能是代码中某些字符的编码问题，因为错误提到了 UTF-8 的问题
刚刚发布了android issues forum bug

【解决方案3】：

尝试删除隐藏文件夹.IntelliJIdea 并重新导入您的项目。

【讨论】：

只搜索我的 win 10 C: 驱动器，没有任何迹象 IntelliJIdea*。是的，我已禁用不显示隐藏文件系统文件夹。你知道这个文件夹在哪里吗？
路径示例：c:\Users\username\.IntelliJIdea14\ 这可能会有所帮助；）path depending of OS
这是残留物，我没有那个文件夹，它一定是在我的 Win 10 安装中出现的窗口
