I have finished the Layout exercise and wondering why they include the call to populateFields() in both onCreate and onResume.
According to Activity Lifecycle “onResume” will always be performed before the Activity is shown so why not just there?
I have real production code that populates fields and is only called in onResume and it works just fine.
I thought one reason would be that maybe onResume is called after the activity is shown, but a bit of googling digs this (mostly unrelated) thread:

Quote: onResume() is thus the last thing that happens before the UI is shown
This is what Dianne Hackborn says so i guess we can trust her 🙂
