Caching the actual profile object is important when the fragment is on an activity's back stack: when it is shown again, onCreateView will be called with profile already set and the service already connected. In this case, there is no later notification from which to bind the profile, so the existing object needs to be bound there. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
