title: SecurityException: Unable to find field for dex.jar
body: <p>How do I solve this error? I tried:</p>
  
  <ol>
  <li><p>Refreshing the project, and rebuilding.</p></li>
  <li><p>Cleaning the project, and rebuilding.</p></li>
  <li><p>Closing and reopening the project, and rebuilding</p></li>
  <li><p>Deleting the project (but not deleting the files — that's a
  checkbox on the project deletion confirmation dialog), and re-
  importing it as an existing project, and cleaning and rebuilding.</p></li>
  <li><p>Deleting the project, deleting the <code>.project</code> and <code>.classpath</code> files in the
  project, and creating a new project using my files as existing
  sources.</p></li>
  </ol>
  
  <p>None of these worked. How do I solve this problem?</p>
