So a couple of things I found out (and I think I understand what was happening)...
You will be able to detect cancellation in doInBackground() only if you code it in such a way. This "detection" is not by means of an asynchronous callback. In other words, doInBackground() should check for cancellation status periodically and handle the case where cancellation has been requested.
Can you post a snippet of your doInBackground()?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
