For hardware: I think SparkFun has some kits that let you do BT reliably with Android devices. For Skymap, that's a separate app, not related to Android per se, and you're free to find it and build it independently, as for the Android framework, there's nothing in it specifically that will let you get values from Skymap and send them to other apps. kris -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
