Answer 1

If you’re talking about AsyncTask then you can call its cancel() method. If you pass true to this method and the task is waiting on some object or I/O operation then the waiting will be interrupted and the task will be cancelled. But if you pass false to this method or the task is not waiting (e.g. performing some calculations) then it will not be cancelled. In this case you can call isCancelled() method from doInBackground() and finish calculations when isCancelled() returns true.
