Notify other activity of a preference changed
<p>I'm trying to have the main activity notified of a change in preferences in the PreferenceActivity but the onSharedPreferenceChanged  is not firing when I change the preference.</p>

<pre><code>    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    prefs.registerOnSharedPreferenceChangeListener(new OnSharedPreferenceChangeListener()
    {   
        public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key)
        {
            Log.d("Dict", "PreferenceChanged: " + key);
        }
    });
</code></pre>
