When the fragment is visible to the user…and interactive, it's called Resumed.…If a fragment is visible but doesn't have focus,…then it's said to be Paused.…And if a fragment isn't visible at all, then it is Stopped.…Here are the events that a fragment will go through…as it goes through each of these states.…The first event that happens when fragment…is first created is called onAttach().…This is where the fragment object is attached…to its container, and this event method…gives you an opportunity to save a reference…
