Any app developers here?

I'm a developer by trait, but it's all in the world of Microsoft (yeah I know ... oxymoron much?), but I REALLY want to get into app development on Android.  I did some playing around with it a couple of years ago, but nothing concrete ever came from it. 

So any app developers looking to code for the N7 or Jelly Bean specifically?  I haven't looked at the new API to see what's new in 4.1, but from what I hear there's some neat new toys with this latest version.
