    After browsing so many tutorials this is the most complete and logical one! Great job!

    One question here:
    Where do I capture the scenario where the QR code is empty (i.e. there is QR code but it translates to nothing)?

    Which is it – at the “if(result == null)” or at the “if(result.getContents() == null)” of onActivityResult method?
