QUESTION
I am using the library https://github.com/felipenmoura/qr-code-scanner
to implement scanning of the QR codes. I am facing two problems -
- Google chrome throws the following error whenever I click the button to trigger. The library works fine on Safari.
Uncaught (in promise) OverconstrainedError {name: "OverconstrainedError", message: "", constraint: "facingMode"}constraint: "facingMode"message: ""name: "OverconstrainedError"__proto__: OverconstrainedError
- The camera feed doesn't work for mobile phones (both safari and chrome). It opens the camera, and doesn't show the live feed, instead it keeps on showing a static image
I am not sure if this is the best library for QR code scanning. My aim is to implement a button that triggers the camera, scans QR,enter image description here and puts the scanned string into the input field.
My code is -

QUESTION
I'm using Android studio 4.0, coding in Kotlin and I'm still really new at Android development.I need to integrate the Xzing barcode libray. I've copied some code from the tutorial at [https://tutorialwing.com/implement-android-qr-code-scanner-using-zxing-library-in-kotlin/][1]. The tutorial uses the following import statement:
...ANSWER
Answered 2020-Jul-01 at 15:06The ZXing library is no longer maintained, and that particular class (IntentIntegrator
) only supports android.app.Fragment
which is the deprecated Android framework version of the AndroidX Fragment
class.
You have a few possible options here:
Fork the ZXing library, and change the
android.app.Fragment
import to use theandroidx.fragment.app.Fragment
version instead.Delegate the
IntentIntegrator
calls to yourActivity
instead, and have the results forwarded to yourFragment
.Simply duplicate the
Intent
initialization code fromIntentIntegrator
to a helper class of your own. TheIntentIntegrator
methods are just convenience methods to build anIntent
and callstartActivityForResult()
. You'll still be able to use theIntentIntegrator.parseActivityResult
method to interpret the result that comes back.
I would recommend going with option #3.
As a longer term alternative, you may also want to consider looking into Firebase ML Kit since ZXing is no longer maintained.

Before posted I did search for this answer but didn't find what I need so would like to ask if you kindly can help me.
I have iOS Swift app that scans QR codes which is in my case calendar event then show it as alert popup. What I need is to scan QR Code (calendar event) and when scanned prompt if Event will be added into calendar, also limit scanning to event QR Codes.
Code that worked was from https://medium.com/@gayatri.hedau/qr-code-scanner-with-avcapturesession-ios-swift-5007ee498b49, but there you can just confirm that you have seen scanned info.
QR code with event info is created on https://qrcode.tec-it.com/en/Calendar

QUESTION
I am using Zbar C++ library to decode QRCode,using this tutorial: https://www.learnopencv.com/barcode-and-qr-code-scanner-using-zbar-and-opencv/
Here I have to decode only QRCode from an image however using this tutorial it decodes both QRcode and barcodes from an Image.
In tutorial it says to decode only QRCode we have to Configure Zbar Imagescanner properly.
In tutorial they are using following configuration to decode both QRCode and Barcodes
ImageScanner scanner;
scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1);
So to decode only QRCode I am using following configuration:
ImageScanner scanner;
scanner.set_config(ZBAR_QRCODE, ZBAR_CFG_ENABLE, 1);
But using this Zbar configuration still it decodes both QRCode and barcodes data.I am getting Decoded Data type as EAN-13 and QR-Code.
How I can configure Zbar sccanner properly so it decodes only QR-Code Data type?
