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

The thing is, if the language is not listed in the language selection list on the device, the resources can never be used as the device can never be put in this configuration by the user.

On the other hand, if the device allows you to select Basque, it will be using this format, and your resources will be used.
