Is it based on zxing ? Well done anyway !
Hopefully they will include a barcode generator as well sometime soon.

Hopefully this would encourage phone manufacturers to bake in support for reading barcodes in their "camera apps". Means one less buttons to press.
I don't know, but I don't think so. I guess the downside is that it's only available in fairly new versions of Android, but looks like a good option where available.
This seems to imply that this feature is implemented within "Google Play Services"
