I guess I'll take a look at the APIs in 5 years, when it has enough market share to be worth considering.
Jelly Bean still has 30% market share, but are owners of 4 year old phones a significant portion of app revenue? I'd wager the people spending money have at least KitKat.
Lollipop, at a year and half old, has another 30%
Digital Signage platforms especially (the part of the Android market I actually care about) seem to be largely stuck on 4.1.

Don't know if I wasn't paying enough attention when I replied, or if you ninja-edited, but that's certainly relevant context.
I have millions of installs for my apps and my minSdk is 16, and I'm very close to bumping it to 19.
