Im not sure I fully understand your problem, but you could add a call to recreate() into the onResume of the activity which from my understanding has the activity go through the entire lifecycle again.

In order to make sure that you only do this when there is in fact dirty data, I would set a flag in the SharedPreferences that lets your activity know in the onResume() that it needs to be recreated.

    public void onResume(){
            super.onResume();
            SharedPreferences pref = getApplicationContext().getSharedPreferences(Constants.PREFS_NAME, Context.MODE_PRIVATE);
            if(pref.getBoolean("isDirtyPrefs", true))
                recreate();
        }
