android - Change language AND country programmatically

I'm developing an app that allows user to change language in app's settings. But as long as some countries have 2 or more languages and some languages are used in more than 1 country, I need to use xx-XX format. For example, users from Belgium can select French or Dutch language.

I use the next code snippet to change language:

protected void setLocale() {
    Resources res = getResources();
    DisplayMetrics dm = res.getDisplayMetrics();
    Configuration conf = res.getConfiguration();
    Locale locale = new Locale(dataManager.getLocale().toLowerCase());
    Locale.setDefault(locale);
    conf.locale = locale;
    res.updateConfiguration(conf, dm);
}

dataManager.getLocale() returns String like "fr-BE" or "nl-BE".

I have following resource files:

values-fr/strings.xml values-fr-rBE/strings.xml values-nl/strings.xml values-nl-rBE/strings.xml

But even if I set locale to nl-BE, it uses strings from values-nl directory, but not from values-nl-rBE.

So, my question is: "How can I make my app to use resources for certain language AND region in runtime?"

You should specify the country in the second parameter of Locale constructor.

Locale (String language, String country)
Constructs a new Locale using the specified language and country codes.

For example:

Locale locale = new Locale("nl", "BE");
