Break the classes into core classes that deal with handling the backend logic, the fragment and rest.
LaunchVPN, MainActivity, ConfigConvert are public API that is recorded in shortcuts, launchers etc. Moving them would break public API. Also VPNProfile belongs into core but since the reading VPN Profiles depends on the class name keep it in the main package.
