Gerald -- Just want to say all of your videos since day 1 on MAUI have be EXCEPTIONAL!!! They are all well articulated and are extremely helpful in adoption of the MAUI platform.

@@jfversluis I've used Microcharts, the google vision barcode scanner for my app, you've taught me how to communicate to and from pages, etc.. Your lessons are priceless. I love .NET MAUI (I've tried Ionic and other frameworks but nothing stuck, MAUI does) and I appreciate you taking the time to respond to me. It's actually really funny... I was talking to my brother about how whenever I need to add something you seem to have released a video about it a few weeks prior which blows my mind. Your tutorials are straight forward and easy to follow. My app looks and functions really well. You have had a major hand in shaping my development, no joke. So Kudos to you! Words cannot describe my appreciation. Thank you. 😄
Hi Gerald! Firstly, thank you for your tutorials, they are seriously helpful. Second, I'm having horrible "scan times", is there any optimizations that I can take? It takes forever for the scanner to recognize the the barcode format and to scan it. Dealing with an application that needs to scan many different types of barcodes/qr.
Oh this is even better than the previous video on barcodes, we can use QR codes too, this great! Can you please make a maui hybrid video also for this scanner (QR)? Btw this package works flawlessly.
@@jfversluisCan I ask you aquestion? I have one problem in my Project. When I create a build, my camera doesn't work. It says "Camera.MAUI.CameraResult.AccessError". It works in Debug, but not in release How can I solve this problem?
Thank you for the intro to barcode scanning in maui with zxing. It works great in my app. One issue... I cannot get the torch to come on when the app first starts. However, it comes on after successfully scanning the first barcode. I set torchenabled=true in both the xaml and codebehind. Thanks for any suggestions.
Hello I am having problem with scanning on bigger camera views. Do you use whole screen for camera view or smaller one ? I have problems when I am using around 50 % area for my camera view, don't know why.
Is there any chance we can get a barcode tutorial for .NET 8.0? I can’t seem to find anything currently. Or might you know of any nuget packages that might work with 8.0? All the ones I’ve found are now broken 😢
Hey Gerald, I followed the video step by step, but when I point the camera at the QrCode or the barcode it doesn't detect anything. I'm using .net 8 android
Hi Gerald, I have a question about this code. Why does the camera not appear when we run it on release mode, but it works when we run it in debug mode?
@@MrPetschko I just bind the Self property of CameraView object to my MVVM: Self="{Binding MyCamera}" and then access all the MyCamera functionality inside of MVVM....
Thanks for the video and the example. I tried to compile for both Windows and Android, but if I launch the project from a PC with the USB camera, it doesn't recognize any barcode. I also tried to specify the format by specifically indicating Code128. If I compile the application by generating APK and inserting it on Android, my OPPO smartphone does not recognize any code. Am I forgetting something?
Help please. Good afternoon. How to clear the camera cache? I want to do the following, I have an application in which I press a button and open the camera, when the QR code is detected, the camera turns off. When I press open the camera again, for 1 second it gives me the old image that I was pointing before, this is very bad when you scan QR codes. How can I clear the camera cache so that when I open it again I don't have the old image?
Gerald, I'm having problems with the component using iOS. iOS is using another camera to scan or get closer to the barcode or QRcode and when I'm using the component in iOS, it's impossible to get the value because it's blurry. Is it possible to change cameras for iOS and use the closer (wild) one?
I am using xzing for qr code scanner it’s work fine in iOS and android . But when I installed on client side it’s work fine all devices but it’s not work one plus mobile . Is it any device specific issue because camera is open but we code not detecting in one plus phone only
hey, do you know some way to do something like that, but using it inside a MVC .net core 6 application? I already have one using javascript and html to read the barcode from the cellphone camera, but it sometimes don't recognize well the codes and don't work...
Scanning QR code with danish carateres (æ ø å). How to read them? string Text = $"{args.Result[0].BarcodeFormat}:{args.Result[0].Text}"; Is it a way to set the codepage used to read/translate the QR code?
No matter what I do I can't get VS 2022 17.11.1 to work with my phone. I've tried two different devices, but they never appear in the ADB devices list, nor do I ever see the Allow Debugging window on my PC. Ever seen that? Of course, all my devices are in dev mode and allow debugging wired and wireless.
Does it work on another version you install side-by side? Do the debugging targets show up in the dropdown? Better file a bug from Visual Studio under Help > provide feedback > report a problem
Hi Gerald, thanks for that Video. Any Idea how I can scan Barcodes on Windows Devices (Surface Pro X)? Do you think this will be supported in the near future?
Hello.... when I try to read QR Codes, it is very slow. Is there a way to increase performance, for example, by zooming in the camera view? Furthermore, is there a way the camera view to draw a frame (or just 4 corners) when a QR code is detected? cheers, Jaime
Hi Gerald currently i am using Camera.Maui but i am getting camera device is already closed in this code await cameraview.StopCameraAsync(); await cameraview.StartCameraAsync(); Please guide me how to resolve this issue
Late reply but for me its a big fat "NO". All my .net android (not maui) classes need explicit declaration because they conflict with MAUI names (View, layouts, etc) which is over 1000+ changes. iOS should be exactly the same so to be honest this library is useless unless its an actual MAUI app
@@jfversluis yeah it would bring to dedicated business apps more identification to product or services. But in general the camera integration is a great approach for maui 👍
BEAWARE: In my case it is not working if you set camera view width / height to size of display device. If you have this small sizes for camera view (as in video) it works perfectly.
@@jfversluis Event Barcode_detected is not triggered in 90% of test cases. I was able to detect only QR codes and it took me around 15 seconds until it detects QR code. All this is happening when you have camera view width and height same as display device height and with. If you have smaller width, height for camera view you don´t have this problem and you are able to scan 1D barcodes as well as QR codes. So I think MAUI.Camera have problem with detection when it process bigger frame ( picture / bitmap with higher height and width).

Hi Gerald, fantastic video, this clarified some doubts I had. Is there a possibility to have the camera view on full screen?
Sure! If you set the correct layout you can make it any size you want! :)
You're a great mentor. Thanks for the guidance!
You’re very welcome!
Hi Gerald. Do you know if there are any plugins which allow you to use the camera's zoom feature to scan smaller codes more easily?
Thanks for providing us with this reference. I found it very useful and helpful
Glad to be of service!
Thanks for the video!! Did you notice a performance difference between all those scanner plugins? Which one do you think is faster?
Didn’t test very extensively but I would think this one feels faster than the other!
does it work in .Net8? I created a new one in Net8 but it just open the camera, not detecting
It doesn't detect it here either, did you manage to resolve it?

Hi Gerald. We have a mobile device with a built-in barcode scanner. How should we approach this?
See if the vendor has some kind of SDK that you can use
SDK or maybe they push the results directly into the keyboard hook. Select a textbox to get focus and try to scan something.
How about NFC or RFID Reading
Is on my todo list!
@@jfversluis that is great. can't wait to watch it. have a nice day.

Also Windows I think!
