i think what this boils down to, is that you need to build everything with 2.0 SDK, and then just make sure you're not using any APIs from versions you don't want. And you will want to abstract away calls you don't have using reflection. Simply doing something like "if (version >= 2.0) then makeSpecialCallTo20Feature();" won't work since the JVM pre-verifies and will wind up barfing saying it can't find that special feature anywhere (even though when it goes to execute, it won't need it anyway). somewhat annoying, and it sure would have been nice if the android folks had just provided a big reflection abstraction layer for all new SDK features...
