Android closing child activity from parent activity

Question

I wanted to close child activity from parent activity. My flow is like: activity A is opened, inside Activity A I am opening activity B. But at same time my activity A is doing some background task. When I got result of my background task I wanted to close activity B from Activity A.

Is it possible to do that?

Answer 1

You can start activity B by using startActivityForResult (Intent intent, int requestCode) then you can close activity B by calling finishActivity (int requestCode).

Answer 2

What you should do is start your activity with startActivityForResult(yourIntent, childId);

Then, when you want to kill your child activity, try finishActivity(childId);

Answer 3

you don't need to finish() every activity once you leave it, Android will do that for you. so you just restart Activity A to the top task .
