QUESTION
I have two classes, App and qrCode. The qrCode class returns a image of the qrcode based on the address provided in that classes state. The app class displays the qrcode component. In the method getSessionID, the app makes a request to the server, then should call updateQrCode to update the qrcode that is being shown.
How can I call the method updateQrCode from App.js? I can't instantiate a new QrCode, because that is not the instance that is being displayed.
App.js:
...ANSWER
Answered 2021-Jun-13 at 00:30App.js is the parent component and QrCode.js is the child component. From parent to child you can pass by props directly.
In App.js, create a state object and update it on receiving fetch response. React re-renders component and its children whenever state object changes.
App.js

As we know, Paytm has launched a Dynamic QR device to display invoice/bill QR Code image.
I have to integrate this device with a billing system(POS), where I have to send QRCode data to this device.
I have to integrate it using C#.NET
Note:- As per the device guidelines, we can transfer data from system to device using USB Port(the serial port communication) Reference
...ANSWER
Answered 2021-Apr-10 at 06:39I got the solution after a discussion with Paytm Development Team. They have shared an SDK along with an API that is used to transfer data from POS(PC) to the Paytm Dynamic QR display device.
This SKD has basically main three methods:
- Show Home Screen on display
- Show QRCode on display
- Show Payment Success message on display
QUESTION
I've been trying to fix this for weeks but failed, when I click on login (indicated with the id "lin") to open a new activity the app crash, i don't know if it's a problem with the Intent or something else, here is the code. The manifest should be ok so I think it's a problem in the MainActivity with Intent ab. The other activity is called Qrcode. I tried to change appcompatactivty to activity but didn't work, i don't really know what to do.
Edit: I posted the code of the qrcode activity, i got it from the answers of this question : Android, How to read QR code in my application?, only for educational purpose of course.
Edit 2: logcat posted, sorry for any issues with asking this question, it's the first question i ask here.
Logcat
...ANSWER
Answered 2021-Jun-03 at 17:42ur code in MainActivity seems ok and I think don't have any problem. In my opinion your Qrcode Activity has some bugs in it, like onCreate method, you should see the Logcat logs in android Studio, btw u can attach the Qrcode activity codes here, it is really helpful. another way to find the bug is by using the try-catch in your code and log the exception

Answered 2021-Jun-01 at 18:56The base64 value you provided in your question is malformed, my recommendation is to not use Json Serialization for this Api response effort.
Try using Convert.ToBase64String

- and the jQuery request accepts/expects

Install qrcode
You can use qrcode like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
