Where gen/R.java should be created in Android Studio project?

Question

I don't know if this folder is existent at my project. I have already executed my application but I'm not finding this folder at my project. Where is it usually located?

Answer 1

R.java will be automatically created for your project by android-studio once you build the project. You can find it at:

your_app_name/app/build/generated/source/r/debug/your_package_name/R.java

You might not be seeing that folder in the project explorer of android-studio, because by default it's set to Android view. Change it to Project view.
