I've been trying to get [this](https://code.google.com/p/barcodefragmentlib/wiki/HowTo) library to work in my android app, but I can't get it to work successfully. I have the fragment showing and the camera shows fine, but it doesn't seem to scan anything (QR, Barcodes etc). I've implemented the call back interface and still nothing happens.

If anyone could give a small example of how to set up the library to scan product codes (code 128) it would be a massive help!

Also, I've already looked at other related questions ([here](https://stackoverflow.com/questions/11558574/a-qr-scanner-inside-of-a-fragment) and [here](https://stackoverflow.com/questions/4782543/integration-zxing-library-directly-into-my-android-application)) and I still can't get it to work.

Thanks
