Lets say I code an App using the 0.9 SDK version. Now I change the SDK version locally to 1.0RC and recompile... ERROR!
Some classes are changed, removed and methods renamed/signature changed etc..
How does this "effect" my app then trying to deploy/install in on a real G1 device. Do I need to know the phone's actuall version, can the user upgrade if I set the requirements or do I need to apply preprocessing and build different versions for different SDK's ?
