title: Why build and libs folders in Android project can't be commited or pushed?
body: <p>I'm using Android Studio in combination with GitHub repository. So I have just pushed my entire project but I mentioned that I can push only my src folder. Is there any reason that I can't push my build and src folders or just I'm doing something wrong? When I'm trying to commit them I'm receiving a message telling me that there is no changes detected, but when I go in my repository there is no such folders.</p>
