某些较旧的插件不再与最新的Android Studio(目前为4.1)兼容.此外，他们似乎已使用此新版本更改了plugins文件夹的位置.

Some older plugins are no longer compatible with the latest Android Studio (4.1 right now). Also, they seem to have changed the location of the plugins folder with this new version.

您将必须卸载插件.就我而言，我看不到IDE设置中列出的插件.我不得不手动查找和删除文件.

You will have to uninstall the plugin. In my case, I couldn't see the plugin listed in the IDE settings. I had to manually find and delete the file.

新插件的位置为:

C:\Users\*username*\AppData\Roaming\Google\AndroidStudio4.1\plugins

删除那里的插件，错误应该消失了.

Delete the plugins there and the error should be gone.
