problem
Plugin “Smalidea” is incompatible (supported only in IntelliJ IDEA).
Plugin “FindViewByMe” is incompatible (supported only in IntelliJ IDEA).
The plugin has not been updated and cannot be used. However, these two plugins are not visible in Plugins and cannot be uninstalled.

Find the corresponding plug-in under C:\Users\Administrator\AppData\Roaming\Google\AndroidStudio4.1\plugins. Just delete
