Use features introduced in a later SDK version in an earlier version
Pergunta
I want to implement a pinch to zoom function in one of my apps, my problem is that this is only supported by Android 2.2 and most but not all of my user base is 2.1. So my question is, can I implement this feature without causing incompatibility with 2.1?
Solução
See this article on backward compatibility for a suggested approach on dealing with newer apis in older versions.
