AndroidStudio : Cannot resolve symbol MainActivity

Question

I got an error \"Cannot resolve symbol MainActivity\" on this code.

Answer 1

It's possible that your 'src' directory isn't set as a source directory?

Your IDE seems to be seeing your com.example.fovoapp as a simple directory structure instead of a package. Also looking at your linked image, the little "J" on the java files tells me that also. When a java file is set as source usually it shows up as a Class "C".

I could be wrong but make sure you set your src directory as source and that should fix the issue.
