title: Android Dex: UNEXPECTED TOP-LEVEL EXCEPTION: Already added
body: <p>My app depends on a library project. This library project depends on the Android Compatibility Package V4. I have <strong>NOT</strong> exported the library project's dependency. In my own project, I've added ACL V13 as a dependency, but when compiling I get the error that essentially there's a duplicate dependency. I thought not exporting the library project's dependency would resolve this issue, but it's not.</p>
  
  <p>How can I resolve this?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Also, according to <a href="http://tools.android.com/recent/dealingwithdependenciesinandroidprojects" rel="noreferrer">Android tools docs</a>: </p>
  
  <blockquote>
    <p>Special case for android-support-v4.jar and android-support-v13.jar.</p>
    
    <p>We make a special case for these two libraries because -v13 contains a
    full version of -v4 inside. If both are found, then only -v13 will be
    used.</p>
  </blockquote>
  
  <p>So it should just work...</p>
