For IOMX, code built with either froyo or gingerbread works on both of 
them IIRC.

For Stagefright, you need to build on gingerbread for it to work on 
gingerbread (or manually declare the missing constants).

So in practice, the ABI of these APIs is kinda stable between these 
releases, but there's no guarantees for this. And for newer qualcomm 
devices, you need patch 18 and the android header patch mentioned there 
(which applies to both froyo and gingerbread), and having this patch 
applied shouldn't break things for other devices, IIRC.
