title: How to comply official android Calendar app from downloaded source?
body: <p>I've recently downloaded the source-code of the official android jellybean calendar app:<br>
  <a href="https://android.googlesource.com/platform/packages/apps/Calendar/+/jb-mr2.0-release" rel="nofollow">https://android.googlesource.com/platform/packages/apps/Calendar/+/jb-mr2.0-release</a></p>
  
  <p>I've imported the code to eclipse, but I can't comply it because a lot of packages are missing like <br></p>
  
  <ul>
  <li>com.android.datetimepicker.date</li>
  <li>com.android.colorpicker</li>
  <li>com.android.ex.chips</li>
  <li>com.android.calendarcommon2</li>
  <li>etc...</li>
  </ul>
  
  <p>What am I doing wrong? Am i supposed to search and hunt for all the packages and add them manually? </p>
  
  <p><strong>EDIT::</strong></p>
  
  <p>Now I told that it's built against the whole OS not just the SDK, so my new question is how to add the whole OS to the eclipse project to make the app work?</p>
