QR scanner and focus

[darosior]

Don't know if it comes from my mobile or from Lamp but i have a hard time scanning bolt11 QR codes: my camera does not focus.

@darosior Thanks for reporting this use case, can you add more information on the Android device?

Such as:

• Model Phone, maybe I can use an emulator to reproduce this issue.
• Android version.

Thanks

Thanks @darosior, I think autofocus doesn't work always good https://github.com/lvaccaro/lamp/blob/3e42713b3ab51304237239fad2702d62b2c36b7b/app/src/main/java/com/lvaccaro/lamp/activities/ScanActivity.kt#L29

The app is still using https://github.com/dm77/barcodescanner based on zxing, but it looks archived by the owner. So we have to migrate to a better scanner solution.
