title: Loading ADF causes crash in Explorer
body: <p>When I create an ADF with the AreaLearning Demo in Java then open the ADF in Project Tango Explorer it crashes every time. I first wrote my own Java ADF creator app, and it crashed Explorer so I decided to try the Java Area Learning demo to see what I did wrong, but it crashed Explorer too.<br>
  Is there an incompatibility? Shouldn't an ADF be an ADF? I just want to make sure I'm not missing something, or messing something up.Thanks.</p>
