Required: Android jargon mastery; knowing what fragments are.
Sadly, I fail at both.
I did tag it Android. Android developers should know what Fragments are. The very short explanation is that a Fragment is a UI module that you can reuse across different Activities. See https://developer.android.com/guide/components/fragments.html for more deets.
Right? I went in thinking this was about the Android platform fragmentation. Still have no idea what a fragment is, other than some chunk of software.
