title: How to import an existing android Project into another android project
body: <p>i want to import an existing Android Project(a small App that should be added to another Android Project soon) into another Android Project in order to test.
  <br>I tried several things for example: </p>
  
  <ul>
  <li>export the first project als jar and add the external jar to build path of the second</li>
  <li>added the first project to the second in the build path of the second project</li>
  </ul>
