is there a way to have a view use a different layout when an
orientation change occurs.
suppose i want the view to look one way in portrait and another way in
landscape -- all the same data, but arranged differently.
I'm thinking one way to do this would be to have two different linear
layouts w
w resources as possible, so i don't want the
app widget starting a service or doing anything until it is triggered.
I guess I could create a very small local service in my app widget,
that I guess could simply be used as a way for my resource intensive
service to be able to communicate with it..
I need some help understanding how this works.
I have an app widget that extends an AppWidgetProvider to create an
application widget.
I would like the application widget to be idle until an activity in my
app runs; actually when a service in my app is started.
Once that service is started, I n
approach should 100% work.
