Let's say I publish an app to the Google Play store with the minimum SDK set to Jelly Bean MR2 (API 18). Later, I realize that I want to be supporting back to Ice Cream Sandwich (15).
Does Google Play allow updates to be pushed that change the minimum SDK? Can I simply change the min SDK from 18 to 15 and (assuming everything works correctly) push an update?
EDIT: I have re-written the question to show a more viable use-case
