title: Meaning of Choreographer messages in Logcat
body: <p>I installed the latest versions of <code>SDK (API 16)</code> and got the latest ADT. I'm now seeing these messages in the logcat, that I'm quite sure, I haven't seen before. Does anyone have an idea about this?</p>
  
  <blockquote>
    <p>06-29 23:11:17.796: I/Choreographer(691): Skipped 647 frames!  The
    application may be doing too much work on its main thread.</p>
  </blockquote>
  
  <p>I did a search and found this link:
  <a href="http://developer.android.com/reference/android/view/Choreographer.html">http://developer.android.com/reference/android/view/Choreographer.html</a>. This is a new class introduced in API 16.</p>
  
  <p>I need to know how I can determine what "too much work" my application may be doing as all my processing is done in <code>AsyncTask</code>s.</p>
