title: Android: does Activity onCreate load at app start-up?
body: <p>I am trying to solve a problem with a RecyclerView list. I'm wondering does the RecyclerView Activity's onCreate method run at app start-up or only when I run the MainActivity method (an Intent) that launches the RecyclerView?  Meaning, does Activity B's (the RecyclerView's) onCreate method run at app start-up or only after Activity A launches Activity B?   </p>
