title: How to destroy previous activity in Activity?
body: <p>I have four activity, i.e. A, B, C and D. A launches B, B launches C, C launches D. When C is launching D, I want to destroy the activity B depending on the situation(logic for that will remain in activity C) so that when I go back From D, it will follow D->C->A path. So I want to destroy activity B from C. How it is possible?</p>
