As far as I get it these are the relevant files:

One directory above you will find values-pt-rBR where somebody already did it for Portuguese.
Creating a new directory called values-es-rLAT or sth similar would be a good idea I suppose.
Keep in mind that not all the verbal output of the application is organized with these files. There are still some hardcoded english messages and labels.
