Android Studio inline compiler showing red errors, but compilation with gradle works fine Ask Question

I've set up my project in Android Studio to use the Square Wire library, as per this question.

Build -> Compile Project works fine.

2:03:10 PM Compilation completed successfully in 31 sec

However, if I open one of my generated Protocol Buffer files, then the Square package is not being recognized.

Another symptom is that methods inherited from the Square Message class are showing as "Cannot resolve method" compile errors in the editor, even though they build and run fine.

Do I need to do something more than just adding the dependency in build.gradle for my module in my project?
