warning: I am total beginner. I have got /e/ on an S7 that is my first smart phone ever.
I can’t scan QR-codes. This is quite a pain.
I installed syncthing. When it came to add another device to sync with, I had to type the lengthy syncthing-device-id into my S7 by hand. There was an icon for transmitting the device id by QR-code. When I click it a dialog opened asking whether I want to install “Barcode Scanner”. I said yes but then came an error like “App not found”.
So I tried to install “Barcode Scanner” via “Apps”. It covers QR codes as well and I could install it. But it wouldn’t start, instead it said that there are missing components and that it need to be reinstalled via google playstore.
What did I do wrong?
Another question in that context: does syncthing want a specific QR-scan-app or could it be any any app and apps have some sort of attributes telling us what they can do (such as “scan QR-codes”) so that other app can depend on such a function rather than on a specific app?
