I am using ZXing.Net library to scan/read QR codes from camera in Windows Phone 8.1. I went through this sample: https://github.com/wildabeast/BarcodeScanner. But this is for Windows Phone 8.0 Silverlight apps which uses following namespaces:
using Microsoft.Phone.Tasks;
using Microsoft.Phone.Controls;
These namespaces are not available in Windows Phone 8.1 as my project is targeted to Windows Phone 8.1. Is there any other plugins to solve this problem in HTML/JS/WinJS/Cordova?
You can follow this post Vinicius Linck. Hope this might help. This github repo really helped me lot. https://github.com/vinnylinck/CordovaW8BarcodeDemo
