B4A Library 1D and 2D Barcode Scanner with ZBAR - another Barcode Scanner that is 100% embedded in B4A

The attached project wraps the ZBAR part of this Github project. It looks very much the same as the project that I have posted here. Both projects use the same ViewFinder but they use different decoding engines (ZXING and ZBAR respectively).

I have not tested all the barcode formats but it should scan the following types:

BarcodeFormat.PARTIAL
BarcodeFormat.EAN8
BarcodeFormat.UPCE
BarcodeFormat.ISBN10
BarcodeFormat.UPCA
BarcodeFormat.EAN13
BarcodeFormat.ISBN13
BarcodeFormat.I25
BarcodeFormat.DATABAR
BarcodeFormat.DATABAR_EXP
BarcodeFormat.CODABAR
BarcodeFormat.CODE39
BarcodeFormat.PDF417
BarcodeFormat.QRCODE
BarcodeFormat.CODE93
BarcodeFormat.CODE128

There seems to be an issue with the scanning of PDF417 codes. I have emailed the author of the Github project (Dushyanth Maguluru) and brought it to his attention. Will update and post new library files once the issue with PDF417 codes has been resolved.

EDIT 26 Feb 2016: See this post as far as scanning of PDF417 is concerned
https://sourceforge.net/p/zbar/support-requests/76/

Please take note of the xml files in the /Objects/res/layout and Objects/res/values folders of the B4A project should you start a new project from scratch.

Posting the following:
1. B4A project demonstrating the Barcode Scanner using the ZBAR decoder
2. Library files - you need to download them from this link (too big to upload to this post) - unzip them and copy them to your additional library folder

See if this starts the scanner. I have replaced your Main Activity with my original Main Activity code, have removed some views from your B4A layout, and commented out just about everything in your code modules. Have also replaced your b4a manifest entries. The scanner starts......

I would suggest you start adding additional stuff bit by bit and test every step after adding additional code to make sure you can trap when and where it goes skew.

Hi Johan
I had try your previous project https://www.b4x.com/android/forum/t...feb-2016-new-library-files-in-post-105.60155/
and find out that can't read PDF417codes (I know that you made wrapping), so I try this version with Zbar, but only what working on my LG M160 is this last example. All
previous version got some problems that want open camera or crashing. What is important that quality of reading simple short code not exceeds ZXING and because small viewer frame larger codes don't read like almost every PDF417 don't fit in frame, so if there some improvements or is problem with my LG?

Please see this from post #1 of this thread

EDIT 26 Feb 2016: See this post as far as scanning of PDF417 is concerned
https://sourceforge.net/p/zbar/support-requests/76/

At the time of doing the wrapper for ZBAR it did not support PDF417 codes.

If you are targeting SDK 28 in the B4A manifest then you will have to add runtime permissions to the B4A project. Please zip and upload a sample project that does not work for you so that I can take a look at it.

Good morning, i'm using zbarcode reader and i'm having trouble reading 1d barcode.

It seems it can't get correct focus in all light conditions and the images received seems not good. I don't think is a camera problem, i'm testing it on huawei p30 phone.

Is there any settings to get better results?

thanks

....the images received seems not good....
I am running it on a Samsung SM-G973F and it has no problem to read 1D barcodes. It is easily reading the barcodes from my laptop's screen with a back light on or off. Do you have a specific barcode (type) that gives you a problem? Can you please clarify "the images received seems not good". Where are the images that you are referring to?

I am running it on a Samsung SM-G973F and it has no problem to read 1D barcodes. It is easily reading the barcodes from my laptop's screen with a back light on or off. Do you have a specific barcode (type) that gives you a problem? Can you please clarify "the images received seems not good". Where are the images that you are referring to?

I ve done some trial. It seems the problem is happening when i try to use the scanner in portrait mode. I have setted it for best usage. When using scanner in portait it does'nt seems to be able to read anything, when in landscape mode it works fine.

The scanner works only in landscape mode?

Hi, I am testing this library and it was working fine. But I have updated to the latest version of the library and now the app always stops on the line:
frontCamId = zb1.FrontFacingCamera
Why can it happen?
Thank you.

Same Problem here, using Honor 10 in portrait mode.
Have upgraded it to the latest library in post 1.

I remebered, on Honor 9 Lite, it was OK.

Hi Johan,

I've been playing around with this as an alternative to our software which runs on dedicated scanners. Is there any way of limiting the scan area to the central portion of the image? If I have multiple barcodes visible, it's sometimes picking one outside the viewport. Also, on my phone it can take a little while to focus, which I think would be improved if the focus distance started as close as possible. I don't know if this sort of control is possible but If it is would make this much more usable.

Great work 👍
