Real QR code scanner - without using another app

[makiwara]

Hello! Is is possible to build an app contaning a built-in QR code scanner?

I watched several tutorials but none of them contained a possibility like this. (In all case the user should download a seperate QR code scanner app)

Thank you for your answer! Have a nice day!

Yes a developer can build an app containing a built in QR code scanner.  You use the BarScanner control

Try this tutorial  https://appinventor.pevest.com/?p=1086  

Did you read the Block documentation?   The documentation explains how to use both an external scanner (which most tutorials do) but it also explains that it can use its own internal code

• BarcodeScanner

The BarCode scanner tool  uses an external scanner by default.  On the Designer screen, Properties for the BarCode tool, untick the UseExternalScanner   box and App Inventor will use the built in scanner code .

Some devices do not have an auto focused camera; many of these devices  have issues focusing on some bar code images such as a QR code using the Camera .  All scanners used the device Camera.

Did this help Makiwara?
