onResume of new Fragment called before onPause in Android Oreo 8.0

Question

I am facing trouble with android Oreo. My MainActivity has 4 fragments, which replace each other whenever the user presses tabs. Now the problem is, I am saving a value in a singleton instance in onPause. Whenever the user presses the next tab, onResume of that fragment is called before onPause, so I am not able to retrieve the value from the singleton correctly.

Please use setReorderingAllowed as false to get the normal fragment lifecycle.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
fragmentTransaction.setReorderingAllowed(false);
}
