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);
