Android Fragments: how do I save and pass data back to parent activity once the user closes the current activity?

Issue

I have a SearchFragment and a PersonFragment which are hosted by different FragmentActivitys

The user will navigate from the SearchFragment to the PersonFragment. When the user is done with the PersonFragment (such as when they press the back button), I would like to send data back to SearchFragment so it can update its UI with any changes the user made while in PersonFragment.

I read the best way to do this is in the Activity's finish() method. However, since I'm using fragments I'm not sure how to accomplish this.

Solution

Ended up using EventBus for this
