What would you like to do?
Android FLAG_ACTIVITY_FORWARD_RESULT howto
Nav flow is: A => B => C => A with results from C
If you're using fragments please note that "onActivityResult" will be called according to where "startActivityForResult" is called (method "startActivityForResult" is available in both, activity and fragment)
ActivityA
startActivityForResult(intentB, 22);
ActivityB
intentC.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
startActivity(intentC);
finish();
ActivityC
setResult(99);
finish();

I think that finish() in ActivityB is unnecessary.

This is actually perfect been looking for this exact description. You need to finish ActivityB otherwise you are left looking at it when ActivityC closes. Something that got me was I was in a fragment in Activity B, so had to call getActivity().startActivity() instead of the fragment's own startActivity()
