[android-developers] Re: How To Determine Which Dialog Was Dismissed

Thank you, Ian and Kostya, for your replies.

As far as the brittleness, it may just be my own personal bias. I work
mainly on large multi-threaded, multi-server apps where objects are
constantly being serialized and de-serialized. Seeing an == comparison
of two references is always a red flag in a code review. I'm still
learning the Android application life-cycle and I wasn't sure if an
onPause/onResume pair of events may cause the == to fail.

I like the idea of using small specialized OnDismissListeners for each
dialog rather than having my activity implement OnDismissListener. I'm
going to switch over to that approach. I'll sleep better, even if my
fears are unfounded. :-)

Thanks again,
Dave
