title: How to import individual projects from Android Source Code
body: <p>As far as I understand, all the built-in standard apps like (email, music, calendar etc) are built using the same API. So I should be able to import a  project like mail / music etc without checking out the full source repository of android. I'v been trying that but I am getting compilation problems like class resolve failure. </p>
  
  <p>Am I doing it wrong? Do I have to get the full android source project to import a project like Mail ? </p>
