  <p>This is my code of adapter to getView of the listview.</p>
  
  <p>ListView Contains the list of contacts from the android.</p>
  
  <p>but i am getting the <strong>java.util.concurrent.RejectedExecutionException</strong>
  Async task basically get the image from the server and if any number matches to the server data that will contain one image to set otherwise not.</p>
  
  <p>So what should i do to avoid this exception?</p>
