title: Build multiple android apk with differnt setting with one project
body: <p>I have three android app projects which has all the same codes except different logos, app icon and different page titles. I was wondering if its possible to make one project and have some kind of build setting that can be used to build three different apps ?</p>
  
  <p>Currently if I update a class file I would have to update in all of the remaining projects manually. I would love to have a way to just update once. How to overcome this problem? Thanks!!</p>
