What makes you think that forking threads in a loop is a good idea in the first place? — CommonsWare, Dec 13 '10 at 13:21

In my experience with AsyncTask, calling cancel(boolean mayInterruptIfRunning) doesn't necessarily stop the execution of the background process. All that seems to happen is that the AsyncTask will execute onCancelled(), and won't run onPostExecute() when it completes. The behaviour probably depends on exactly what code you have in doInBackgound()

True. Check isCancelled() regularly in doInBackground() to see if you should stop the work and finish yourself. – icyerasor May 03 '11 at 14:32

In my case I perform server requests with HttpPost, HttpGet and so on. The only way I found to end an AsyncTask was calling the abort() method as you can see in the following example

if (isCancelled) {
     try {
         //cancel the task and immediately abort the HttpRequest
         uploadTask.cancel(true);
         post.abort();
     } catch (UnsupportedOperationException e) {
         e.printStackTrace();
     }
}
