Setting application locale to pt_BR programmatically

Question

I have an application that has support for the Portuguese language, both for Portugal and Brazil regions. I have created a values-pt (containing the Portugal translation) an

Answer 1

I assume you're targeting Android OS > 2.2, because both Portuguese languages are supported by Android starting at version 2.3+.
I tested it on the emulator, by swapping language & keyboard and having only 1 string different: app_name, so it appeared in application title and it worked just fine.

The only difference is that I named Portugal region values-pt-rPT insead of values-pt.
I didn't test on the fly-relocalization, but I guess it works as well.
I think that when you work with regions, you MUST specify a region for every localization (i.e. fr-rFR for France and fr-rCA for Canada) and can't use the default (pt in your case, or fr in my second example).

This link illustrates the whole thing more deeply.

[EDIT]

When creating a new locale by code, try:

final Locale myLocale = new Locale("pt", "PT");

and

final Locale myLocale = new Locale("pt", "BR");
