In your concrete implementation you have to declare a default constructor which calls the public IntentService (String name)
super constructor of the abstract IntentService class you extend:
public MyService () {
super("MyServerOrWhatever");
}
You do not need to overwrite onStartCommand if the super implementation fits for you (what I expect).
In your current case you should get an exception (Unable to instantiate service…) – it is always worth to put this in the question.
