The code you sent seems fine to me. I have the suspicion that maybe what is
wrong is in the xml layout file for your second screen. (Maybe put a
breakpoint into the second onCreate(). If you can reach it the intent
negotiation is right. It might blow up when you are trying to load the
screen layout).
