No, it does not stack; armor AC is of type "armor" and the spell, too, so, they are both of the same bonus type and therefore they do not stack :) (there is also no exceptional rule for that type)

My tip is don't use the description of the spell to guess what it does. If the spell does not explicit say that it does something it does not do it. There are exeptions that are up to interpretation, but I think this is a good foundation when trying to figure out spells.

From the description it sounds like that it is a force field and that there should not be any reason it could not stack with armor. But it says armor bonus, and it does not say it stacks with other armor, so it does not.

If a character already wears armor it's pretty much useless UNLESS the enemy is an incorporeal creature, in which case the armor would get ignored, but that +4 will still work
