title: Import Android project error
body: <p>I download a Android open source code from web.</p>
  
  <p>When I import it to library,it don't have a "gen folder",so I manually</p>
  
  <p>create one then I use "refresh" and "Project clean ..."</p>
  
  <p>The eclipse still don't auto generate the R.java file.</p>
  
  <p>And why I can't "" import com.codeminders.ardrone.ARDrone;"</p>
  
  <p>I already have the folder in my project.</p>
  
  <p>How can I fix this?!</p>
