title: What effect does the export library checkbox have on a standalone project?
body: <p>I was under the impression that the export checkboxes in Eclipse's project properties "order and export" tab was only used as a convenience so that dependent Eclipse projects wouldn't have to include the same library as their parent projects. </p>
  
  <ol>
  <li>Does checking the export boxes for a library in a standalone project
  have any effect at all?  </li>
  <li>Does building for Android behave any differently than a standard Java project?  On one of my Android projects, I get a class not found runtime error unless I check the export boxes on couple of my libraries.  How could this happen?</li>
  </ol>
