How to manipulate Activity back stack?

I found the answer here how to kill sub activities and bring activity to top of stack.

I don't know if you actually can manipulate the stack of application like your suggesting in your title. My app runs in opengl so I never actually change form one Activity to another but I think the following principle will also work: Why don't you call the Activity you want yourself? It is really straight forwards in the back button event to handle this.

On back pressed -> load activity you want if your in activity A then exit.

I thought of that too but the code some how doesn't look clean to me. I just found another answer Thank you for your contribution. – Ragunath Jawahar Nov 22 '10 at 5:46 no problem, I'm just glad you found the answer you needed ^^ – Jason Rogers Nov 22 '10 at 5:48.

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.
