Where does greenDAO generator code go?

I'm investigating greenDAO for an Android version of one of our iOS apps that heavily uses CoreData functionality.

I'm confused on how to start though. I've seen the DaoGeneratorExample code, but I'm not confident on how that relates to my project.

Let's assume my project is called MyApp. Do I need to create a SECOND Android project called MyAppDaoGenerator which I just run to generate java files and put them in the MyApp directories?

Or is the schema generation supposed to exist within the MyApp code?
