Like Dimitris said: Try to call 'cancel(true)' on the AsyncTask. It will invoke the thread's 'interrupt()' method, making sure that if the thread is in a wait-state, this wait-state will be interrupted.
Then in the onCancelled() you may be able to get hold of connections/ etc from your AsyncTask, used in the 'doInBackground()' method, that are open and then forcefully close them.
