Can someone show a noob why my Bundle is always null? The source of
my activity class is below, and I consistently get the following
debugging output:
DEBUG/Compass(18473): onCreate. bundle=null
DEBUG/Compass(18473): onResume
DEBUG/Compass(18473): onSaveInstanceState, save bearing -1.0
DEBUG/Compass(18473): onResume
DEBUG/Compass(18473): onSaveInstanceState, save bearing 191.37694
DEBUG/Compass(18473): onStop
DEBUG/Compass(18520): onCreate. bundle=null
DEBUG/Compass(18520): onResume
DEBUG/Compass(18520): onSaveInstanceState, save bearing -1.0
This is AFTER leaving the app, doing lots of activity to make sure it
gets cleared from the stack, and returning. Once I see that "save
bearing" line with something > -1, I expect to see a bundle in the
next onCreate.
Am I doing something goofy in my onSaveInstanceState?
Thanks for any help!
