Is it possible, at runtime, to know which resources languages are embedded in my app?
i.e the presence of this folders:
values-en values-de values-fr
these res-lang actually depends on Locales, so you need to get locale from device and you can get which language is getting shown from locale..
Locale myPhoneLocale = Locale.getDefault();
You can then call getDisplayLanguage() to know which language is getting shown.
Reference : Locale
