Ask HN: Experienced programmer wants to learn native mobile dev quickly

17 years of experience, seen all the paradigms come and go, have a solid CS background. So far, I've stayed away from native mobile development, choosing to specialize in other areas.

Looking for any resources (free or paid, print or online) that will get me up to speed on native development quickly, ideally geared towards experienced programmers so I don't have to wade through chapters on setting up IDEs, etc.
