Change language of app

I'm trying to change the language of my app.

I implement this code : 

public static void setLocale(Resources res, String lang) {
    Configuration conf =  new Configuration(res.getConfiguration());

    switch (lang) {
        case "French" :
            conf.locale = new Locale("fr");
            break;
        case "Dutch" :
            conf.locale = new Locale("nl");
            break;
        case "English" :
            conf.locale = new Locale("en");
            break;
    }
    res.updateConfiguration(conf, res.getDisplayMetrics());
}

And after that I refresh my activity using this code : 

Intent refresh = new Intent(getActivity(), HomeActivity.class);
getActivity().finish();
startActivity(refresh);

This code works, but when I close the app (remove from background) and reopen it, the language return to the default language of my device.

Is there any way to keep the selected language when I reopen my app ?

you can store in default shared Preference:

PreferenceManager.getDefaultSharedPreferences().edit().putString("Locale", localVal).commit();

and than every time the app start retrive it by:

locale = PreferenceManager.getDefaultSharedPreferences().getString("Locale", "defaultValue");
