ZXing.Net.Mobile | Barcode Scanner for Xamarin.iOS , Xamarin.Android , UWP | Form library

I am trying to implement barcode scanning in my Xamarin form, but no success.
I am able to get the camera working, but I don't see the red line on the screen and it simply refuses to scan anything

I tried this answer. I can see thru my camera, but no red line appears. But I can put the torch on and off

XAML code:

I am currently training a bit of bindings and MVVM in Xamarin.Forms XAML. I have a view with a grid and I want to bind a whole View to it as a child.

Further I am using ZXing.Net.Mobile.Forms and their views, which I want to display.

Programmatically it is no problem with grid.Children.Add(MyView);

But how can I achieve the same result with bindings in XAML?

Thanks in advance!

My Xaml in which the View should be binded to:

I am using ZXing.Net.Mobile in a Xamarin.Forms project. It works fine on iOS, but on Android, the first time I use the scanner, I get the camera permissions popup, and grant them.

There is no image from the camera immediately after the permissions. If I quit the app and re-launch, the camera works fine from that point forward. How can I get it to work right away? Even if I close my view, dispose and re-initialize it, it still doesn't work until the app restarts.

Here is relevant code:

I am using the ZXing.Net.Mobile NuGet package for scanning barcode numbers. I have done everything as per this blog.

My Code

I use Zxing.Net.Mobile in my Xamarin Forms project.

I call ZXingScannerView to the page but scanner options seems to be not working. I set specific type of barcode to scan but it sill scans everything in focus.

I call scannerview at page.xaml:

I'm developing a Xamarin Forms iOS app. In the xaml file, there is a grid.

I'm trying to get the result of a scan using a MobileBarcodeScanner. If I save the result as a var everything works fine, but as soon as I try to use ZXing.Result, I get the message The type 'Result' exists in both 'zxing, Version=0.16.5.0 ...' and 'zxing.portable, Version=0.16.2.0 ...'

I have these packages installed:

• ZXing.Net.Mobile.Forms, Version 2.4.1

• ZXing.Net.Mobile, Version 2.4.1

• Zxing.Net, Version 0.16.5

I've seen other people use ZXing.Result, do I have an extra package installed? Am I missing one? Is there a way to mitigate this conflict?

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 want to explain my app logic. My app is viewing PDFs. There are 2 ways to show pdfs.

1. The user logins the app and clicks the Show PDF button. Then, App opens a new window and the user selects a pdf for see it.

2. The user opens a pdf from his phone storage and shares that pdf to my application. (If the user didn't login to the app before, App opens the login page.)

The first one works fine. But when the user shares a pdf to my app from his phone storage, Application opens my HomePape Automatically.

There are 2 public LoginPage(){} in the app.

1.public LoginPage()

2.public LoginPage(string _pdfUri)

The first one lets user login the app. The second one if user didn't login the app and shares a pdf to the app. In this way, the app gets pdfpath and opens the PdfShowPage.

Lets check the code,

App.xaml.cs:

/* I debugged this. App always comes here even when The user shares Pdf. Because of this, PdfShowPage LoginPage works and LoginPage(string _pdfUri) does not work. The app opens HomePage. Basicly;

LoginPage() -> HomePage

LoginPage(string _pdfUri) -> PdfShowPage
