Hello All,
Here is a library that I wrapped for generic Android 1D/2D laser barcode scanners.
You don't need a library to use a generic Android 1D/2D hardware laser barcode scanners. To receive barcode data you can use an Intent via a Receiver Module without the need for a library, but there can be conflicts. For instance, the Camera2 library does not work while the scanner is open(on). This is because the barcode scanner module itself is classed as a camera and you can't run 2 cameras at the same time. I used the original barcode library that I've got to close(off) the barcode scanner module then I can use the Camera2 library to take photos (for example stock item images), after that I can open(on) the barcode scanner module again. Yes this can also be achieved via JavaObject, but hey
Take note: This library does not work with normal mobile phone built-in cameras, just selected Android powered 1D/2D laser barcode scanners.
Personally I only purchase and supply to my clients, barcode scanners that use the Honeywell N6602/N6603 (N660x) laser module or variants of them. According to sellers that I've interacted with, the SDK that I've used will work with some other none Honeywell laser modules, but I personally can't vouch for that. Yes generic Android powered 1D/2D laser barcode scanners cost more but the build quality (of the thicker/heftier scanners), scanning distance and the speed of scanning barcodes are clearly superior to using smartphone cameras.
B4A library tab
There are 3 files in the attached zipped library folder, place them all in your additional libraries folder.
I've changed some of the functions for simplicity purposes.

Below are some examples of generic Android powered 1D/2D laser barcode scanners that this library could work with (4 definitely work), plus much much more. No guarantees thought.
Enjoy...

Some scanner functions:
BScannner.SetScanBeep(True)
BScannner.SetScanVibrate(True)
BScannner.SetIndicatorLightMode(True)
Log($"Open the scanner: ${BScannner.OpenScanner}"$) 'Laser scanner is turned on and will scan
Log($"Is scanner open: ${BScannner.IsScanOpened}"$)
Log($"Get beep state: ${BScannner.GetScanBeepState}"$)
Log($"Get vibrate state: ${BScannner.GetScanVibrateState}"$)
Log($"Get indicator light state: ${BScannner.GetIndicatorLightMode}"$)
Log($"Get broadcast mode: ${BScannner.GetOutScanMode}"$)
Log($"Get scan mode: ${BScannner.GetScanLaserMode}"$)
Log($"Scanned barcode value: ${BScannner.GetScanCodeValue}"$)
Log($"Reset the scanner: ${BScannner.ResetScan}"$)
B4A logs:
** Activity (main) Create (first time) **
Success: Scanner module found
Scanner mode: Broadcast mode
Open the scanner: true
Is scanner open: true
Get beep state: true
Get vibrate state: true
Get indicator light state: true
Get broadcast mode: Broadcast mode
Get scan mode: Single mode
Scanned barcode value: null
Reset the scanner: true
Call B4XPages.GetManager.LogEvents = True to enable logging B4XPages events.I've changed some of the functions for simplicity purposes.
