title: Which method gets called in the parent activity when the user clicks on Back in the child activity?
body: <p>I have 2 activities in my Android app: A and B. A is the parent of B, as defined in the Android manifest. When stepping through my app with the debugger I've found that when I click on Up in the child activity, B, the onCreate() method of A gets called. But where does control pass to when the user clicks on Back in activity B? Which method of its parent activity, A, gets called?</p>
  
  <p>I've read lots of stuff about navigation in Android, Back vs Up, etc., but I can't find an answer to this simple question. (I would like the Back button to behave like Up in my app but I can't get A's screen to update correctly when the user clicks on Back in B.)</p>
