Android localize es-r419

Question

I\'m localizing my app and one of the language/region supported is Espanol-419. Android doesn\'t support the naming convention values-es-r419 but it does accept values-en-rGB.

Answer 1

Android 7.0 (API level 24) brings more robust resource resolution, and finds better fallbacks automatically. However, to speed up resolution and improve maintainability, you should store resources in the most common parent dialect. For example, if you were storing Spanish resources in the values-es-rUS directory before, move them into the values-b+es+419 directory, which contains Latin American Spanish.

We offered language selection in-app, so to work well on new and old phones we kept duplicate resources in values-es-rUS Español (Estados Unidos) as well as values-b+es+419 Español (Latinoamérica)
