I'd like to ask how to implement internationalization, i.e. the texts inside the app can change according to the device language.
For instance I'm having String1, String2, String3 that would be "A","B","C" if the device language is English, and "X","Y","Z" if the device language is French (or anything else than English).
I do not need automatic translation, I just need to know what is the default language already set on the device so depending on that I may modify some strings (or do other actions) myself.
