Use the Public Suffix List

[qgustavor]

It currently uses a regex:

privacy-friendly-qr-scanner/app/src/main/java/com/secuso/privacyfriendlycodescanner/qrscanner/ui/resultfragments/URLResultFragment.java

Line 60 in cbbf609

Pattern pattern = Pattern.compile("([0-9a-zA-ZäöüÄÖÜß-]*\\.(co.uk|com.de|de.com|co.at|[a-zA-Z]{2,}))$");

Because of that it highlights wrongly a lot of domains not in the regex. Using the public suffix list is probably the best way to handle those cases: https://publicsuffix.org/
