Scanning QR code does not work (missing feature?)

Hi, thanks for this great FLOSS initiative!

I suspect this is not a bug in the existing program, but a feature that has not been implemented (yet). When I use an app that scans a QR code for something, it never recognizes the code. Instead, it just keeps the camera running indefinitely.

When running logcat on the device, the following stack trace jumps out:

I’m assuming this means the vision module is not present in the Microg implementation. Is there a way to provide this module? If I’m reading the Google documentation correctly, the Vision API is superseded by Firebase ML Kit, which is now in beta. After a quick search I found that parts of Firebase are made open source. Could we somehow include Firebase in Microg, or am I way in over my head here?

Vision Barcode API is now added via 5e39818a20032d261215420fc72e05efad4202b5.

Confirmed not working for Belfius Mobile and Payconiq. The SecScanQR workaround does work for some applications (Sometimes you need to cut a piece out of the scanned URL/Code, but at least it does the trick). But not if the applications don’t offer a way to enter the codes manually / refuse to work without the Google QR Code API… Which is the case for both these apps 😕

Any sight on implementation? Or another workaround to be suggested?
