title: How can I make a ProgressDialog be cancelable by the back button but not by a screen tap?
body: <p>I would like to make a <code>ProgressDialog</code> cancelable by the back button but not by a screen tap.  Currently I use <code>setCancelable(true)</code>.</p>
  
  <p>However, in some newer devices a tap on the screen also cancels the <code>ProgressDialog</code>. I'd like to disable the screen tap action while the <code>ProgressDialog</code> is shown.</p>
