Asynchronous task not cancelled in android

Question

I have called asynctask.cancel(true) in a button click after the async task starts.i am checking for iscancelled value in doinbackground and wrote condition accordingly.the conditions is

while(myProgress<phnno.size()){

                if (isCancelled()) {


                    break;
                }else{
                     myProgress++;
                        publishProgress();
                           SystemClock.sleep(100);
                }

               }

But still the asynchronous task is not cancelled.Could anyone give suggestions regarding this. Thanks in advance

Silly question - you are definitely calling isCancelled() on the same Asynctask you created earlier right? — Ken Wolf, Jun 07 '13 at 10:45
@hemanthkumar elaborated in an answer. If this isn't it please post where you create and later cancel this task... — Ken Wolf, Jun 07 '13 at 10:54

Guessing because I haven't seen all of your code.

Make sure you are calling cancel() on the same AsyncTask object. Don't create a new one.

Like so:

AsyncTask myTask = new AsyncTask();
myTask.execute();

Later, when you want to cancel

myTask.cancel();

add this method in asynctask:

@Override
    protected void onCancelled() {
        running = false;
    }
