Does startService() create a new Service instance or using the existing one?

Does startService() create a new Service instance or using the existing one? For example, in the following code, does it create two UpdateService instances or just one UpdateService instance? Thanks.

    int[] appWidgetIds = new int[] {1, 2};  
    for (int appWidgetId : appWidgetIds) {
        Intent intent = new Intent(context, UpdateService.class);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
        context.startService(intent);
    }

The onStart method is deprecated for now, use onStartCommand instead.

If the service is already started, it does not start as second copy, but onStart() is still called on the existing instance. Services are natural singletons -- there is exactly 0 or 1 copy of the service in operation.
