Barcode Reader sample app not decoding certain barcode types

HeathcliffRongo — Fri, 08 Feb 2019 01:39:35 GMT

Using AppStudio 3.1, I can't seem to get the Barcode Reader app to decode Code 93 and UPC-EAN barcodes.

I've tested the following barcode types, which all work fine.

Code 39

Code 128

EAN 8

EAN 13

UPC A

UPC E

QR CODE

DATA Matrix

I've tested on various Android and iOS devices and experience the same issue. Have also tried decoding barcodes on my computer monitor and in printed form - no difference.

I checked the release notes for 3.2 and didn't see any mention of any barcode filter related fixes. Anyone else had similar issues?

Hi Heathcliff,

The Barcode Reader is powered by zxing libraries which is defined to support CODE 93. However see what other people have said about their CODE 93 issues Issues · zxing/zxing · GitHub

This issue 743 is particularly interesting Issues · zxing/zxing · GitHub as it includes a testing: http://zxing.org/w/decode?u=https%3A%2F%2Fcloud.githubusercontent.com%2Fassets%2F15977592%2F21809695%2Fd59153c6-d76e-11e6-927a-79f4c156a065.png

Presumeably you could upload your CODE 93 to gist.github.com (or similar cloud base service) and run it through the http://zxing.org/w/decode?u= tester.

Hi Stephen,

Appreciate the extra information. I'll give the validation a go at some point. Cheers.
