Do I need to start and resume the OntouchListener?

Well if you let the listener attached to the imageview or not doesn't effect on the cpu or battery life. I mean of course have effect but that is not something that you should care, it is not like listeners of compas you can do this button1. SetOnTouchListener(null) but I told you there is no need to unregister onTouch listeners If you are concerned for memory usage or cpu usage you should pay attention on other things.

Unregistering touch listener will not help to you application to be better or faster.

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.
