This is a wrap for this Github project. You will need to download ZxingLatest.jar from the link below and copy it to your additional library folder:
https://drive.google.com/file/d/0B4g9tud5lvjgOGxENXZZcjVrZDA/view?usp=sharing
Extract LibRes.zip and copy the folder and its contents to be on the same folder level as that of the B4A project's /Files and /Objects folders.
Copy the other B4A library files (attached) to your additional library folder.
Nothing of interest happening in the B4A manifest file.
Have done this B4A V7.30 and on a KitKat device. It should work with earlier versions of B4A (and in all probability with Android versions earlier and later than KitKat)
Once the app started - click on the centre of the black square
Scan a code
To scan another code - click on the previously scanned/displayed barcode
Have tested it with:
Aztex codes
QR codes
PDF417
EAN13
DataMatrix
Sure a whole number of other barcode types can also be scanned as the decoding is done by the Zxing engine.
