@Giriton yeah, that crash is coming from deep inside the ZXing library the plugin uses for decoding barcodes.

[Giriton]

@macdonst I see, thank you for clarification. As far as I found out, this plugin uses barcodescanner-release-2.1.5.aar form here https://github.com/EddyVerbruggen/barcodescanner-lib-aar , correct?

On that page, @EddyVerbruggen says:
Update any source files as needed (current version is: https://github.com/zxing/zxing/releases/tag/BS-4.7.6)

However that version 4.7.6 is from September 2016. Current newest version 4.7.7 is from October 2017. So my question is, is it possible to perhaps update version of BS (Barcode Scanner) used from ZXing to current 4.7.7 ?

In ZXyng, there is a commit that did something around this very row, where the error appears from:
zxing/zxing@2f11529#diff-3ea115340f67fb0e31e24e4cd9ae7582

So updating Barcode Scanner.aar would update also ZXyng engine used in Barcode Scanner.aar and if problem persist, I know it is still not fixed problem of ZXyng. In that case I can open issue there. Until then, I can not be sure whether the mentioned commit was or was not included in currently used 4.7.6.

Hope it makes a sense :-)
What do you think?

One of my users is facing a similar issue with ZXing library and the crash log looks similar to what you have mentioned.
Android Version is 6.0

Would love to see if there is any update on this issue.

I have detected a similar error on a device with android 7.

Camera error after opening.

[jarekskuder]

Same here, only my app crashes immediately after i open scanner

same here

Also on windows 8.1 this issue

[bpetty-formfast]

@michielsebille , as for the comment about Windows, we were getting the same behavior but were able to get around it by creating a published version. In VS go to Project/Store/Create App Packages. A regular release build would pop up and instantly crash, but having not looked at an error log I can't say if it is related.

[Alipric2019]

Same here, too.

I really need this barcode scanner works on Android 6, at least!!!

[CristianoGil]
