title: App Inventor app works in emulator, but not on my actual phone
body: <p>I've got an app inventor app built and working pretty well in the emulator.  When I put it on my phone none of the code runs.  The app doesn't crash, but the code behind the objects doesn't do anything.  I've got code which runs on screen load which doesn't fire, and my buttons don't do anything.</p>
  
  <p>The drop downs show the menu item, but that's it.</p>
  
  <p>Does anyone have any ideas?</p>
