[android-developers] OnSharedPreferenceChangeListener never receives callback

Hi folks,

I'm trying to listen for preference changes from an activity (see below). It never fires. Is it due to the fact that the activity in question is not in focus when the change event fires?

sharedPrefs = PreferenceManager.getDefaultSharedPreferences( getApplicationContext() );
       
SharedPreferences.OnSharedPreferenceChangeListener prefListener = new SharedPreferences.OnSharedPreferenceChangeListener()
{
  @Override
  public void onSharedPreferenceChanged( SharedPreferences sharedPreferences, String key )
  {
     Log.w( TAG, "Pref key: " + key );
  }
};
sharedPrefs.registerOnSharedPreferenceChangeListener( prefListener );

Cheers,
Stacy
