Minimum android api 2.2 or 2.3 for cocos2dx 2.1.4

Hi all!
Just been looking at cocos2d and trying to get it up and running on my max os x, but end up with a blank screen when I run the project. 8(

I just wanted to check what the minimum android api is. When I create the project it says 2.2 is, but in the readme.mdown file it mentions 2.3.

Thanks for the confirmation, Tim.
