How do I get the OS (i.e. Android) language ?
OS.get_locale() may be what you are looking for.
Thx it worked !
I don't know why it's called like that btw :/
It's called "locale" because it refers to a set of region-specific parameters; see the Wikipedia page on locales.
You would use OS.get_name(). See here.
Sry my question wasn't precise. I asked for the languages like english french spanish etc...
