[android-developers] Re: Activity Help

The spinner and the list on the first activity are "self contained" - that is their state won't directly affect the activity that you're calling.  Sounds like the activity you start is trying to access some data/resource that is not there (e.g. your layout is missing a resource). 

Check the state of variables during the onCreate/onResume/etc lifecycle functions to see where the NPE is generated.

Can you post a stacktrace?
