CRZXing is a Java library for decoding barcodes from a bitmap image rather than from an image taken with the camera.
This library is based on the ZXing library from Google.
The attached zip file includes a B4A test app (built with B4A version 3.82) and the wrapper XML, jar, and source code. The wrapper was built using the Simple Library Compiler from Anywhere Software.
I have used a specific version of the ZXing library, 3.1.0. You need to download two ZXing jar files, core-3.1.0.jar and javase-3.1.0.jar.
These two jar files can be found at the ZXing website at: http://repo1.maven.org/maven2/com/google/zxing/
B4A Test App:
The test app shows three types of barcodes, a UPC/EAN barcode, a Code39 text barcode (notice the "!" is encoded as "/A" by ZXing), and a Darth Vader barcode
that returns null to indicate decode failure.
I haven't tested, but I would guess that this library also works with B4J since it is pure Java. Also not tested is decoding QR codes, but I would expect it to work.
