android - cancel AsyncTask class in onPostExecute -

i'm inspecting other's code. , have seen there.

@override     protected void onpostexecute(autobookmarkinfo result) {         super.onpostexecute(result);          // computation...          if (setautobookmarktask != null) {             setautobookmarktask.cancel(false);             setautobookmarktask = null;         }      } 

setautobookmarktask - instance of asynctask class. please, explains why guy tries cancel working thread when work have been done ?

setautobookmarktask.cancel(false) doesnot mean anything. if need interrupt or cancel async task have pass true in argument.
