should I use IntentService or Service for UI update?

Question

I'm wondering whether it makes any difference to use the IntentService class rather than the Service class in an android widget for managing UI updates (and registering onClickListener ). Below is my code that I use onHandleIntent and onStartCommand respectively.

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this.getApplicationContext());

int[] allWidgetIds = intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS);

for (int widgetId : allWidgetIds) {onClickListener

    RemoteViews remoteViews = new RemoteViews(this.getApplicationContext().getPackageName(), R.layout.main);

    // Register an onClickListener
    Intent clickIntent = myIntent(this.getApplicationContext());

    PendingIntent pendingIntent = PendingIntent.getActivity(this.getApplicationContext(), 0, clickIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    remoteViews.setOnClickPendingIntent(R.id.text, pendingIntent);

    appWidgetManager.updateAppWidget(widgetId, remoteViews);

}

By the way if you want to update UI threads during service calling it is not possible. But Android provides AsyncTasks to handle this kind of scenario. http://developer.android.com/reference/android/os/AsyncTask.html .
