I have implemented an Xamarin App which uses the zxing library for scan the QR. When app is deployed to android device in debug mode it scan the QR but not in RELEASE MODE. Can you suggest me the best way to fix this issue.?
ZXing.Net.Mobile nuget version 2.4.1
Here I have added code snippet which I have used. Also the QR code.
