B4A Library ZXING Barcode Scanner - A wrap for the official ZXING project as it is on 10 July 2016

Always wanted to do this one....This is a wrap for the official ZXING barcode scanning project as what it is today (i.e 10 July 2016). I have compiled the core part of the project, the front end of the project, and the wrapper all into a single jar file.

Note:
1. You can switch on/off the flash/torch by making use of the volume up/down buttons of your device
2. See the folder \resource_zxing in the B4A folder structure
3. Take note of the B4A Manifest file
4. I have added no code whatsoever to return anything to the B4A project (this can easily be done)
5. It supports a range of different languages depending on what language your device has been set too. See the values-xxx folders in the B4A project's \resource_zxing folder for supported languages

Have tested it with scans of the following 1D and 2D barcodes:
UPC_E
EAN_13
EAN_8
RSS_14
RSS_EXPANDED
CODE_39
CODE_93
CODE_128
ITF
CODABAR
QR_CODE
DATA_MATRIX
PDF_417
AZTEC_CODE

You can download the whole lot from HERE:
1. B4A project
2. B4A Library files - copy them to your additional library folder
3. The java code.

Click on your device's MENU button once the scanner has started. Then select SETTINGS. There are a vast number of setting that you can set....

Take it for a test drive....

This may not apply in your case but you must use Java 8 to compile with SLC because BADoclet can produce incorrect XML with Java 11 or later. SLC uses the Java from the B4A IDE path setting.

Erel said a long time ago that he would fix this but it hasn't happened yet!.
