title: AsyncTask Threading Rule - Can it really only be used once?
body: <p>In the <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="noreferrer">documentation on AsyncTask</a> it gives the following as a rule related to threading:</p>
  
  <blockquote>
    <ul>
    <li>The task can be executed only once (an exception will be thrown if a second execution is attempted.)</li>
    </ul>
  </blockquote>
  
  <p>All this means is that you have to create a new instance of the class every time you want to use it, right? In other words, it must be done like this:</p>
  
  <pre><code>new DownloadFilesTask().execute(url1, url2, url3);
  new DownloadFilesTask().execute(url4, url5, url6);
  </code></pre>
  
  <p>Or conversely, you can NOT do the following:</p>
  
  <pre><code>DownloadFilesTask dfTask = new DownloadFilesTask();
  dfTask.execute(url1, url2, url3);
  dfTask.execute(url4, url5, url6);
  </code></pre>
  
  <p>Can someone verify this is an accurate interpretation?</p>
  
  <p>I realize I pretty much just answered this for myself as I was typing this out... But it wasn't immediately obvious to me so I think this would be useful to have posted nonetheless.  </p>
