title: Android Studio 2.1 debugger does not show local variables
body: <p>I am trying to debug over network in Android Studio. I connected via port 5555 and generally it is possible step through break points. But it often takes minutes just to execute one line of code and the other thing is that I don't see any variables which are no members. All I see is the <code>this</code> object, but no variables from within methods. How can I enable it?</p>

  <p>As you can see I am within the method and at least the activity object is initialized, but it is not visible in the variables monitor.</p>
  
  <p>UPDATE:</p>
  
  <p>The problem remains when using USB debugging. No local variables are visible, not even when trying to evaluate expressions while debugging:</p>
