android: `recreate()` not only this, but the last activity also

Question

I use this code to change the locale of my app programatically:

Locale.setDefault(locale);
Configuration config = getBaseContext().getResources().getConfiguration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
       getBaseContext().getResources().getDisplayMetrics());
recreate();

Works like a charme for this activity and all activities afterwards, but if I use the back-function of my cellphone, the last activity is reused, with the old locale.

Any way to invalidate the last activity or to force recreate on it?

This post solved the problem: How to recreate previous activity?

My final solution is:

@Override
public void onResume() {
    super.onResume();
    if(!currentLanguage.equals(getResources().getConfiguration().locale.getLanguage())) {
        recreate();
    }
}

and in onCreate() :

currentLanguage = getResources().getConfiguration().locale.getLanguage();

(Should have searched more).
