title: Referencing external project
body: <p>I have Android projects A and B, where Project B should reference project A. To accomplish that I did the following:</p>
  
  <ul>
  <li>Mark A as "isLibrary" and added it to project B --> noClassdeFoundException</li>
  <li>Added B under "Order and Export": A is checked and listed as first --> same exception</li>
  </ul>
  
  <p>What else can I do?</p>
