title: No debuggable applications
body: <p>I'm building an android app (using Android Studio 1.1.0) and the device I'm trying to test my app is Samsung note 10.1 N8000(Api 16). When I click the bug button, everything is complied successfully but under Android tab under devices it says No debuggable app. I have tried various solution but none is working.</p>
  
  <p>Event log says this :</p>
