android - Custom Multi Language support

Question

I am aware of Creating a new values directory for the language with the suffix of the language code. For german: values-de or french: values-fr then copy our string.xml into that and translate each entry. And this works based on the Phone Localization settings

I wanted to know if we can bypass the phone setting and and make the user select his required language inside the app?

My requirement is, i want to give a language selection option inside my app, and make the user select the language he wants for the app.. how to dynamically switch between the string.xml (for different languages) ???

thanks in advance

Create method which sets your basic Locale.Lets say

public static void setDefaultLocale(Context context,String locale) {
        Locale locJa = new Locale(locale);
        Locale.setDefault(locJa);

        Configuration config = new Configuration();
        config.locale = locJa;

        context.getResources().updateConfiguration(config, context.getResources()
                .getDisplayMetrics());

        locJa = null;
        config = null;
    }

Now check when user selected Locale.(Here basically I have used menu for language selection).

Configuration config = new Configuration();
String newLocale = config.locale.getLanguage().substring(0, 2)
    .toLowerCase();
if ("ja".equalsIgnoreCase(newLocale)) {
// Call above method with context & newLocale
} 
// Sequentially you check for Locale & change that.
