Maybe it is doing:
*Connection: keep-alive*
and you want it to do:
*Connection: close*
Put a breakpoint here:
notifyListener("Chegou aqui");
Then put one here:
notifyListener("Ja tenho qualquer coisa");
Make sure both breakpoints get hit.
Also, please notice that your observers will be getting notified on a
thread other than the UI thread with your notifyListener calls in
doInBackground. You may not want that.
