Catalan and Basque resources in Android

Question

When you want to add locale-specific resources in Android, you have to add the lowercase ISO-3166-1 code of the language to the resource folder\'s name. So far so good.

Answer 1

Adding a new language in LocaleSwitch, you need to type the ISO 639-1 code. For instance, if you want to switch to basque you need to enter "eu". Afterwards, you will see the new locale as "vasco".

That makes me think that basque locale is supported by android.
