Set Locale programmatically

Question

My app supports 3 (soon 4) languages. Since several locales are quite similar I\'d like to give the user the option to change locale in my application, for instance an Itali

@SuppressWarnings("deprecation")
public static void forceLocale(Context context, String localeCode) {
    String localeCodeLowerCase = localeCode.toLowerCase();

    Resources resources = context.getApplicationContext().getResources();
    Configuration overrideConfiguration = resources.getConfiguration();
    Locale overrideLocale = new Locale(localeCodeLowerCase);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        overrideConfiguration.setLocale(overrideLocale);
    } else {
        overrideConfiguration.locale = overrideLocale;
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        context.getApplicationContext().createConfigurationContext(overrideConfiguration);
    } else {
        resources.updateConfiguration(overrideConfiguration, null);
    }
}

Just use this helper method to force specific locale.
