title: What are the folder in an Android Studio project that I have to share on GitHub?
body: <p>I've build an open source app with Android Studio and I've share alle the files on GitHub.
  I thinks that there are a lot of unnecessary files such as those generated by the debugging (that for each commit are uploaded) so, 
  which are the necessary files that i've to share to allow someone to download and open my project?</p>
