What Ted said is absolutely true, I just wanted to add a little tidbit. In the AOSP sources, the code actually checks to see if finish was called from within onCreate and short circuits the displaying any UI. This is so that, if you determine your activity doesn't need to be run and call finish() in onCreate(), you won't get flickering from the activity starting up and then being immediately killed.
