title: Android Hierarchy viewer is not showing timings for rendering
body: <p>I'm having some performance problems with my application and I've found <a href="http://developer.android.com/training/improving-layouts/optimizing-layout.html" rel="nofollow noreferrer">this article</a> for helping me.</p>
  
  <p>The problem is that when I execute Hierarchy viewer, I always have <code>n/a as Measure</code>, Layout and Draw time for each component of the view.</p>
  
  <p>I'm using Android 3.2 in my virtual device.</p>
  
  <p>Thanks.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I add a capture of the Hierarchy Viewer output:

  <p>When I use the Hierarchy viewer with the initial activity (a very simple activity), it works perfectly. But when i used this activity, I can't see the times for drawing each component.</p>
