Kostya,
Thanks for the detailed reply.
For those events that are shared by the two receivers, what happens if
only one sized widget is actually on the home screen? The system sends
the event and it is still processed by "unused" broadcast receiver even
though its widget is not instantiated? That's the behavior I am seeing
and it sounds like you see the same.
With regard to your statement "Multiple broadcasts haven't been a
problem with my setup, because my code double checks widget Ids against
my own known widget Id list for that particular widget size", you still
get the multiple broadcasts but you are smart enough to ignore them?
