BinaryEye does not register as QR app
When BinaryEye is installed and another app needs to scan a QR code, the app asks to install a scanner and does not use BinaryEye.
Hm, that's because Android doesn't have a default Intent for that - see #2
So the question is, what Intent does this app trying to be responded to? Can you tell me from what app you're trying to open Binary Eye?
If you install ZXing's own app (https://play.google.com/store/apps/details?id=com.srowen.bs.android.simple), does it work?
I'm using syncthing from fdroid. When trying to add another device via QR code, the app asks if barcode reader should be installed (it even specifically asks for/suggests zxing) even though BinaryEye (also from fdroid) is installed. This does not happen if zxing is installed.
Interesting, will investigate. Shouldn't happen if ZXing's default client works properly.
IMHO this issue is a dupe of https://github.com/markusfisch/BinaryEye/issues/2
