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 folder. I thought that maybe that folder should be added as a source folder or a classes dependency, but I just can't find it.
Can anyone help?

gen/ folder holds source code that Android's build tools generate.
R. java is the generated file by ADT or Android studio. It will be located under app\build\generated\source\r directory.
R is a class containing the definitions for all resources of a particular application package. It is in the namespace of the application package. For example, if you say in your manifest your package name is com. foo. bar , an R class is generated with the symbols of all your resources in com.
@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
