Answer 1

For anyone stuck with same problem, a symptom not to receive onActivityResult, following cases can cause this issue.

• check you are using startActivityForResult() correctly, do not use startActivity().
• if you do something in overriden onBackPressed method, super.onBackPressed(); has to be positioned at the last of the method, not at the first line. (my case to spend 5 hours)
• remove android:launchMode="singleInstance" in manifest or equivalent argument to create a intent.
• remove noHistory="true" in manifest of the callee activity.
• check setResult() is missed.
• finish() is called to close the activity. use finishActivity() to close callee activity.
• use requestCode more than zero. negative value does not work.
