The current development version requires Android 4.0.3 or newer.
How did I miss that?!?
The latest version that supports Android 2.3.3+ is 4.4.1.
I am not sure whether you can get that from Google Play, but you
might be able to side-load version 4.4 from the ZXing project

Could you elaborate more on the "is not working".
Does it crash? Do you have a log excerpt to show?
