ScannerView | ️ Custom Android View for Scanning QR Codes | iOS library

Probably a dumb question but I cannot figure how make it work. When I press scan button in my IKScannerDeviceView scan works but its delegate never gets called. I put a breakpoint on line

hello i have created the webview in mail activity of the android studio and now i am in scanner activity and when the APP scans any QR code having the link it just writs the link but what i want to do is to open the link in the web view already created in mail activity.

let me place my scanner file here

I'm currently working on a school project QR scanner to just get the text out of the QR code and display it over the next activity. But it just crashed when I use intent but works when it's just display on the scanner activity. ( T .T)

Scan.java

Ok, so i need to display some of my product's database data on the scanner builder window(as shown in the image) when this product gets scanned. Scanner window results

As you can see in the image, the barcode scanner is displayed, my question is: is it possible to print in this windows some other data except from the product's barcode? if yes how should i move?

this is my windows builder code

I want to be able to scan barcodes, then show the barcode at the bottom of the screen in a sheet, or a separate view.

When I update the 'barcode' variable which is @Published and accessed in other methods with @ObserveableObject, it doesn't update the view with the data from the barcode.

Content View

As part of the app i'm developing i want the ability to change between using the front or back camera, but from my searches and attempts i haven't been able to get it to work using the front camera.

The scanner view doing the scanning is the one from ZXing.Net.Mobile.Forms called ZXingScannerView, defined in my xaml like so, together with the button that should do the flipping of the camera.

I'm realising a barcode scanner using Zxing Scanner, everything is working for this part but now I would like to add one button on the layout (to toggle on/off flashlight). I checked everywhere on the internet but found nothing.

So, here is my questions :

• Is it possible de ton find ou modify the .xml to add a button ? If yes, how to find this file ?

• Is there a feature already implemented somewhere to add some elements in the layout?

This is how I'm calling ZXingScannerView :

We have a problem with the ZXing Barcodescanner for Xamarin.Forms. The scanner works perfectly on Android, but on IOS I can't see the camera image (preview). The scanner does scan barcodes on IOS if I hold them in front of the camera but the camera preview is just a white background.

I tried playing around with the options but without luck. We are using Prism.Forms for MVVM.

As I mentioned, my code works well on android. Here are some details:

• The permissions are properly set on both platforms.
• The NuGets ZXing.Net.Mobile and ZXing.Net.Mobile.Forms are added too all three projects (Android, IOS and portable)
• We are using .NET Standard 2.0
• Xamarin.Forms is version 3.4.0

ScannerView.xaml

I'm developing an Android app. That app has the functionality to read QR codes(That's the only capability that has been implemented to it so far). I'm developing the app on Android Studio. Once I install the app on to my android phone, it says permission denied. (Requesting permission has been implemented for the app and the "Permission denied" is the custom message that I've put into the android app in cases where the permission gets denied.).

I can manually give permission to the app on my phone. When I do that, it says permission granted and for a second gets access to the Camera but then "Permission Denied" message starts to appear repetitively and the camera feed get's lost.
