Correct. You cannot pass constructor parameters. If BackgroundHelperService is extending IntentService, please supply a name yourself:
public BackgroundHelperService() {
super("BackgroundHelperService");
}

That worked, I noticed that if I do something like Toast.makeText(this, "Background Helper Service Created", Toast.LENGTH_LONG).show(); it will throw an exception because of the 'this' word. Do you know why this is? It seems that there is no Context for some reason.

@jax: I would not be surprised if you cannot create `Toasts` from services.

I cant even get hold of the notification service. notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

it seems if you do this in the onHandleIntent(Intent intent) it works, you just can't do it inside the constructor

@jax: Never implement a constructor on an `Activity` or `Service`.
