title: Progress Dialog over Content Resolver
body: <p>When i am fetching contacts list through following statement, the UI hangs up and shows black screen. How can we place progressDialog during the time this query executes?</p>
  
  <pre><code>    Cursor phoneCursor = contentResolver.query(
                          PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?",
                          new String[] { contact_id }, null);
  </code></pre>
  
  <p>Placing dialog.show and dialog.dismiss above and below the statement does not work.</p>
