how to kill sub activities and bring activity to top of stack

Question

I have activity A that starts activity B which starts activity C

A -> B -> C

When a user clicks on a button in activity C, i want to bring A to the top of the stack and take B & C completely out of the stack. Is there a way to do this ? ?

Answer 1

What I do is placing a finish() into onActivityResult of activity B depending if the button in C is clicked or not.

I don't know if that's the best way to achieve that, but seem correct for my use.

Answer 2

You can use the FLAG_ACTIVITY_CLEAR_TOP flag on the intent to restart activity A.
