我总是从站点下载更新，删除原始版本，然后在 sdk 文件夹旁边提取新版本。有没有办法解决这个问题？

Answer 1

我找到了解决办法

首先，你应该删除2个文件夹C:\Users\USER_NAME\.android, C:\Users\USER_NAME\.AndroidStudio 并删除C:\Users\USER_NAME\AppData\Local\Temp中的所有文件

其次，卸载并重新安装Android Studio

这种方法效果很好

问题解决了。有点..

将-Djna.nosys=true 行添加到 /bin 文件夹中的 studio.vmoptions 文件解决了我的问题，我现在更新了。我从这里找到了解决方案：https://code.google.com/p/android/issues/detail?id=78656
