How to enable hardware acceleration on ICS, but disable it in Gingerbread?

Question

I want my application to speed up in ICS, but 2.3.3 support is still needed. Can I enable HW acceleration for ICS only? Or can I only refuse support 2.3.3?

Answer 1

Hardware acceleration was not added until 3.0. It's not a problem.

Answer 2

on ICS (android 4+), GPU acceleration is enabled by default and can be disabled in the manifest.
