Maybe, maybe not. It depends on what you want to do.

Re: [android-beginners] Re: Implementing a Service - Call down to super?
But DanH is right, it totally depends on what you want to do. It also depends on what super does... If your subclass is setting information that is also set by super then chances are you would want to call super first. If what super does varies based on settings in your implementation, then you would want to call super last. If there is no such relationship then it doesn't matter when you call. Also, IMHO, you would only want to skip calling super in extremely rare circumstances. And, technically speaking, you would be calling up to the super implementation, but that's just semantics... :-) -- There are only 10 types of people in the world...

[android-beginners] Re: Implementing a Service - Call down to super?
Dan, Thanks but that's not quite helpful! :-) I have my own onCreate and onStart and onDestroy methods that do my service-specific actions. Do I need to also invoke the super-class methods to keep Android happy? And, if so, do I do it before or after I do my own work? ...Jake D == DanH danhi...@ieee.org writes: D Maybe, maybe not.

[android-beginners] Re: Implementing a Service - Call down to super?
Justin,
What you saying is certainly true generically. But I am specifically
talking about a class as follows:
public class JakeService extends Service {
}
In example code I don't think I usually see calls up to the super
implementations. That seems wrong. So when extending the Service class
do you call super before or after you do your own work? Wouldn't the
answer to this question be the same regardless of what my Service
implementation does?
