Important note: This will wipe the shelf, local history, and potentially other cached data.
重要说明：这将擦除架子、本地历史记录和其他潜在的缓存数据。
File menu > Invalidate caches and restart. The PSI cache is one of the caches that are affected by this command, so this should fix it up.
文件菜单 > 使缓存无效并重新启动。PSI 缓存是受此命令影响的缓存之一，因此应该修复它。

Whenever I navigated to a class, I'd get this PSI error. Clicking the details in Android Studio, it included the following:
每当我导航到一个班级时，我都会收到这个 PSI 错误。单击 Android Studio 中的详细信息，它包括以下内容：
viewProvider=SingleRootFileViewProvider{myVirtualFile=jar://<user-directory>/.gradle/caches/modules-2/files-2.1/com.squareup.haha/haha/2.0.3/e0672395ac43377f2510b14839342a24fdf35c18/haha-2.0.3-sources.jar!/com/squareup/haha/guava/io/GwtWorkarounds.java, content=VirtualFileContent{size=5678}}
viewProvider=SingleRootFileViewProvider{myVirtualFile=jar://<user-directory>/.gradle/caches/modules-2/files-2.1/com.squareup.haha/haha/2.0.3/e0672395ac43377f2510b14839342a24fdf35c18/haha-2.0.3-sources.jar!/com/squareup/haha/guava/io/GwtWorkarounds.java, content=VirtualFileContent{size=5678}}
Based on this info, I tried deleting <user-directory>/.gradle/caches/modules-2and restarting Android Studio and it seemed to fix the PSI error, and it didn't seem to delete local history (though I don't know if anything else important was deleted).
根据此信息，我尝试删除<user-directory>/.gradle/caches/modules-2并重新启动 Android Studio，它似乎修复了 PSI 错误，并且似乎没有删除本地历史记录（尽管我不知道是否删除了其他重要内容）。

Invalidating caches didn't work for me. Only a complete re-install of AS and all relevant SDK, Gradle etc... did the trick. I started by uninstalling AS. Then I manually deleted the SDK folder. I also deleted the .gradle and .android folders in my C:/Users/[my.user]/ folder.
使缓存无效对我不起作用。只有完全重新安装 AS 和所有相关的 SDK、Gradle 等……才能成功。我从卸载 AS 开始。然后我手动删除了SDK文件夹。我还删除了 C:/Users/[my.user]/ 文件夹中的 .gradle 和 .android 文件夹。
