copied!<p>You should run all your run logging tasks in this single <code>AsyncTask</code>. It's perfectly fine to do this as it already provides you with a background thread do to all your processing.</p> <p>Just do all your http processing in the main doInBackGround method. </p> <p>Whenever you want to update the UI you have 2 hooks:</p> <ul> <li><code>onPostExecute</code> : This gets called when the doInBackground completes. Put all logic here that you want to perform on the UI when your background processing is done completely. </li> <li><code>onProgressUpdate</code> : This gets called whenever you call <code>publishProgress</code> from within the <code>doInBackground</code> method. Do this whenever you want to update the UI while your background processing is still ongoing. It allows you to show intermediate progress. This will cause the AsyncTasks <code>onProgressUpdate</code> to be called automatically where you can update your UI.</li> </ul> <p>If the adapter used to back your ListView is a member variable of the activity class then you can reference it from onPostExecute and onProgressUpdate meaning you'll be able to update your list either when </p> <ul> <li>the background processing has completed (<code>onPostExecute</code>)</li> <li>when background processing is still ongoing (<code>onProgressUpdate</code>)</li> </ul> <p>An example is shown here : <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">http://developer.android.com/reference/android/os/AsyncTask.html</a></p> <p>Nested <code>AsynTasks</code> are not supported (and could never work).</p>
