            You're not actually fetching the image. You're just storing the literal URL as text in your test.png file.

            First fetch the image:

            How to solve Java.Lang.RuntimeException: 'getParameters failed (empty parameters)'
            Asked 2022-Mar-05 at 22:48

            I have a mobile app in Xamarin where a QR-code scanner is needed. Scanning the code works fine... After scanning a code, the user is redirected to another page. After checking out this page, the user is redirected to the page where the scanner is located. So, when this redirection happens, I get the error Java.Lang.RuntimeException: 'getParameters failed (empty parameters)'... I googled for hours but couldn't find any solution for this problem. BTW, it also happens when I use the 'back' button on the emulator or real word Android device...



            Answered 2022-Mar-05 at 22:48

            --SOLVED-- Changing the PushAsync(pageX()) to PopAsync(); worked in my case. Found out that the problem is bases around getting the camera parameters. These are not available, because the camera is already using it in the former screen. So closing the camera/ending the camera activity is also a solution!

            I tried to create a QR code with QRcode.js library. As of the UI, I can manually click on the button download to download it but I would to download automatically without clicking the button.

            Base on my code bellow.



            Answered 2022-Feb-11 at 09:11

            I've had this issue in the past, and I've worked around it by creating a small util function I can invoke upon button pressing. But invoking it directly at the end of your function should have the same result as a user click, effectively automatically downloading the QR code without user input.

            For Loop

            I am having a view that captures a QR code and displays it on the screen, what I want to do next is take these values by iterating the elements with a for loop and save it in an array, in this case my ID is id="scanned-result" and I want to iterate each containing values and saving to an array.

            I am doing this but for some reason it is not performing the operation correctly. I would like to know what I should correct?

            Since there is no element on your page, as charlietfl pointed out, you won't get any results.

            Since your HTML markup is the following:
