I was working in a Android project and I imported it to another laptop to continue my work, but then I got this error in the project:
Description : R cannot be resolved to a variable
Resource : AccueilFragment.java
Path : /AppV1/src/com/example/appv1
Type : Java Problem
The folder gen(Generated Java Files) contain just the package com.example.appv1--->BuildConfig.java and there is not the file R.java
