Cannot resolve Symbol R, where is gen folder in Android Studio?

Question

I have created a dummy Android project from within Android studio, and I can make it run, but the Editor itself fails to find the R class. In fact I can\'t find the gen fold

Answer 1

@joe_deniable gave me the idea to look closer in the build folder, and I found a folder that had been excluded by intellij, where my R was happily having an ice cream. This was here:

build/source/aidl/debug

I had to remove this folder from the exclusion list and add it to the sources, and could finally start coding in this new IDE.

Thanks
