I have to agree totally on this thought. I'm working with people who have never worked on anything except Android. It is the first thing they did and they don't have the baggage I carry coming into the platform. That puts them at an advantage obviously. There are things that pop up and they will ask someone with Java experience, but it is more likely to be a rare occurrence than the other way around.
