You can use this extension to take photos using the front camera App Inventor Extensions: Camera | Pura Vida Apps and use the captured photo and decode the barcode using another extension Qr : Read and Create Qr/Bar Code offline

Alternatively, use this extension [FREE] ScanView -ZxingView Version 2- Extension - Extensions - Kodular Community

However, it is built in Kodular and may not work in MIT App Inventor (i tried most of the time it does)

how to switch the barcode scanner to front mode.

The answer to Q1 from the FAQ here App Inventor Extensions: Camera | Pura Vida Apps might be interesting for you

There might be another extension, which offers this feature

Make a price checker project in the mit app inventory 2 for a tablet. according to the functions performed, it is also similar to a data collection terminal.I already have it made and it works, but it reads from the main camera.I want it to read from the front camera. After your question, I have another question: is it possible to programmatically switch the cameras in the mit app 2, that is, the main one to the front one?

Switching cameras working OK for me on AI2 in companion with Android 14...

[tama]

I have One UI 6.0 android 14 there is an error on the build. Now I will assemble and show you how my project is assembled...

[Boban]

what version of scan view do you have to begin with, if 2.2 you have to include BarcodeScanner component as well

[TIMAI2]

You might try with the pre-release companion ? Looks like a device issue for API 34...

Help test Companion app bugfixes for Android 14

[image] At least for me this error occurs when deleting various extensions and the only way out is to reload both companion and builder.. P.S. It's not related to this version of companion as it has happened multiple times over the years.

no barcodescanner component needed for me

@TIMAI2

no barcodescanner component needed for me

try by building your app and install it, I get error if I don't have it

Now works fine, with both back and front cameras

[tama]

I have ScanView 2.1, it's a barcode scanning extension based on the Zxing library (Zebra Crossing) for Android. but you should, you say 2.2

[tama]

now I will download and check in 2.2

[tama]

The apk is installed without errors. when you touch the screen, the program does not respond but must scan the barcode

[Boban]

you have to assign an arrangement

see @TIMAI2 post above
