QRCodereader extra buttons not working (torchlight/flashlight, cancel, switchcamera)?

Asked 2021-Feb-06 at 13:16

I've implemented the example app from (https://cocoapods.org/pods/QRCodeReader.swift) to my own project to make a uiview on my main screen that displays a barcode scanner. I can scan a barcode and print the result, but the torchlight (flashlight) button does nothing when pressed, same with cancel and switchcamerabutton, even though the icons are displayed on the view. What could be the problem?

This is my code:

Xamarin Android Webview: getUserMedia fails to open camera

Asked 2021-Feb-03 at 01:25

I'm trying to open the camera and allow the user to capture an image frame from within a Xamarin.Android's webview.

I've pointed the webview to this URL which hosts a few examples: https://googlechrome.github.io/samples/image-capture/index.html. The samples work perfectly when opening the URL in the device's Chrome browser but fails when opened within the app's webview. Here is my WebChromeClient implementation:

How to use result from barcodescanner somewhere else?

Asked 2020-Dec-26 at 23:24

So i have a barcodescan button, I want to press it and scan an item, then retrieve the barcode and use the retrieved barcode in another button (this will send an api request with the barcode), how would i go about this?

Would love if someone could point me in the right direction, cant seem to find any answers online (probably searching for the wrong thing).

Thanks in advance!

This is partially my code:

ANSWER

Answered 2020-Dec-26 at 23:24

You're pretty much there. What's missing here is an extra variable for you to store the barcode scan result in.

On your view controller add something like: private var barcode: String? = nil

It can be assigned a value when you get a result in reader(_: QRCodeReaderViewController, didScanResult: QRCodeReaderResult).

Now because barcode is added as an optional property, in your ANOTHERBUTTON function, you can easily ensure that a barcode value is set before the function does anything by using a guard.

So that would look something like:

QUESTION

How to save JSONdata from API-call(GET) to later use for an API-request(PUT)?

Asked 2020-Dec-26 at 14:21

This is what i am trying to accomplish:

Use a barcode scanner to scan an item and send a "GET REQUEST" to retrieve json data.
Modify the data with user input (change number, text etc).
Use the modified data/variable to send out a "PUT REQUEST" as httpbody.

I dont know what the best way to accomplish this is, im so lost! Can i somehow return the variable "parameters" out of the function so that i can modify it and send it out with another function?

The below code is not the full code, i removed a big part to make it easier to read. It contains a "get" function, dont know where to go from here.

Thanks for checking it out, just looking for someone to point me in the right direction.

Answered 2020-Dec-26 at 14:21

You can use the closure to return the value out of the function. This practice is functional programming, almost using for async function.

AAR is built with your code only. No dependencies end up in AAR by default. Here is an option on how to include dependencies into AAR.

Also, it may be helpful to know about transitive dependencies: Transitive dependencies not resolved for aar library using gradle

To fix the issue with META-INF files you can use Gradle packagingOptions. Inside of your build.gradle file find android block and insert the following:

Not detecting QR codes with firebase ml kit on android but works on ios (flutter)

Asked 2019-Dec-10 at 09:39

My qr code scanner stopped working on Android and I do not understand why... It worked previously and the scanner still works on iOS.

Firebase ML kit simply returns an empty list when scanning and I have tried many different android devices and QR codes but none work (anymore).

I have tried to clean and reinstall all dependencies, I tried to clear all data in Google Play services and reinstalled the app (so that it reinstalls the ML model)

I had an idea that it could possibly be the image format that is not correct, the format from the camera is in YUV_420_888 and I think it is converted into NV21 with the code below, but not 100% sure how that works.

What's annoying is that this did work before but suddenly stoped working.

This is my implementation of the QR scanner it recieves an image from the camera stream

ANSWER

Answered 2019-Dec-10 at 09:39

Edit: As suggested by Frank, the issue was the resolution setting on the camera, if it is to low the QR code cannot be detected. Putting it on "high" or higher sovles this problem.

I solved this issue by rolling back the camera plugin to version: "camera: ^0.5.2+2"

Not sure what exactly breaks the ML vision package for android in the newer version, but this solved the issue for now.
