  <p>I've already added all my external libs so why am I getting always these errors?
  Can anybody help?</p>
  
  <p><strong>EDIT 21.05.2012:</strong>
  The problem is if you add "Dropbox" jar AND "ActionBarSherlock".
  If I add only "Dropbox", I have no problem.
  If I add only "ActionBarSherlock", I have no problem.
  But if I added both, I would get the errors above.</p>
