Sure, you need Context pretty much everywhere the UI and other Android specifics are concerned, but your core objects that represent the general layout of your application should not know anything about what a Context is or have any reason to use it. Just because Context is usually readily available (in your Activity or Service) does not mean you should force arbitrary dependencies on it.

I think (a variation of) MVC is more appropo in this case and definitely simplifies things, IMO. Example: in my app I have a "Bus" object. This has absolutely no reason to know about Context or the Android platform in general. However, when I, say, plot a bus on a map, it's *view* knows about the bus and how it should be displayed, using the current Context. I agree with everything else, though. ------------------------------------------------------------------------------------------------- TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
