First of all, yours is a great job … but I have a couple of questions about some possible improvements.
An easy one is: how about an update of the Zxing library to the brand new version 0.19.1 ?
The second question is about the video input source. I have noticed that in the Zxing library there are methods to allow the user to choose a specific video input source, when there is more than one available. Maybe some scanning process could be better using a different camera.
Thanks anyway in advance
