Menue items are checkable and when clicking refresh button list gets refreshed
Added dialog to select a language
Created language enum
Used for native name and ISO-code
Instead of hardcoding languages and switch case, I used the language enum
Refactor: changed first entry article to be NZZ-website
Selected language gets saved in field
Taken language in account when creating URL for http request
Set default language to avoid NullPointerException
No message
