Force "locale" in application

I want to rotate my phone and keep the locale. I have folders values, values-en and values-hr. In every activity I have

android:configChanges="keyboardHidden|orientation|locale"

and in every activity.java file I have

private Locale locale = null;

@Override
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    if (locale != null)
    {
        newConfig.locale = locale;
        Locale.setDefault(locale);
        getBas开发者_StackOverfloweContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
    }
}

and in onCreate

    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);               
    Configuration config = getBaseContext().getResources().getConfiguration();

    String lang = settings.getString("language","en");
    if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
    {
        locale = new Locale(lang);
        Locale.setDefault(locale);
        config.locale = locale;
        getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
    }

It works till I rotate my phone - app is still working, buttons and everything is fine - but locale is getting weird - sometimes it's my locale (hr) sometimes it's (en)...

What else I need to add?

I simply removed "if's" and everything is working now. Yes, it is a little "bulky" every time to "re-force" a locale but I couldn't find another way.

My solution is a little bit different, I just "re-force" it on onCreate and onConfigChange - not every 100ms or so and on Desire (2.2) it's working flawlessly.

@Austyn

Yes, it's pretty much the same question but I though is there another solution except "100ms forcing".

Users wanna have their mother-tongue (HR) but it's not supported in (current) mobile phones so this is the only way - to force it =/
