title: Add a delay to Progress Dialog
body: <p>I want to make a dummy progress dialog appear for 2 or 3 seconds.  It won't actually do anything other than say detecting.  I have the code:</p>
  
  <pre><code>    ProgressDialog dialog = ProgressDialog.show(this, "", "Detecting...",
              true);
      dialog.show();
  
      dialog.dismiss();
  </code></pre>
  
  <p>But what do I put in between the show, and the dismissal to have the dialog appear for a few seconds?  Thanks!</p>
