I need to determine the user's preferred language(s) and whether their
region uses metric/English. On iOS, these are stored in the defaults
system. I'm not sure where they are stored on Android and other phones.
What are developers using currently to access this type of information?
Ideally, I'd like a cross platform solution. If not, something for iOS
and Android. Otherwise, is there a plugin for NSUserDefaults on iOS? And
what would I do for Android? It seems like I'd have to write a
cross-platform plugin.
