title: How do I display an alert dialog on Android?
body: <p>I want to display a dialog/popup window with a message to the user that shows "Are you sure you want to delete this entry?" with one button that says 'Delete'. When <code>Delete</code> is touched, it should delete that entry, otherwise nothing.</p>
  
  <p>I have written a click listener for those buttons, but how do I invoke a dialog or popup and its functionality?</p>
