howdy, Brian!

Hi, Mark.

I have a question about the Application class

um, OK

In iPhone development, it is common to have a bunch of methods attached to the AppDelegate class

doesn't seem like that is very common in Android development

I'm not sure what role AppDelegate plays, as I'm not an iPhone developer

but I've also read and heard that it is a good place to stick global stuff

it is certainly a candidate

oh, it's kind of like the Application class. It has a couple of callbacks and you can get a reference to it elsewhere in the app

Dianne Hackborn is on record as saying using a custom Application class is not much better than using static data members

anyway, is it a bad idea to put methods on the Application class and then call them from an Activity to manipulate global data?

I've used a custom Application class in a production app, and the results were so-so

it's not a bad idea per se

I would be a bit nervous about using Application as a Context, though

lots of people get bit by problems there

so long as you are treating Application as just some magically-created singleton, I don't think there's any particular problems

OK, I might be conflating with Contexts. I recalled there was an issue there.

with Application versus Activity context I mean

Activity and Service are each subclasses of Context and tend to be better choices when you need a Context

besides, you only get an Application by way of some other Context (e.g., getApplication())

OK. Thanks, that helps a bit

any other questions?

howdy, Mark J!

Heya :)

it's your turn -- got a question?

Not at the moment :) Just hanging out

OK

Oh by the way. You were correct in suggesting my SQLite for my "Checklist" I am working on. I looked into the sdk "Notes" example, it was also what they used.

Or actually it was titled Notepad

yes

it's fairly simple to use

seems to be, I started reading through the book about it. Haven't gotten much work on it yet though.

Zzzzzzzzzzzzzzzzzzzzzzz...

well, any questions before I close down this office hour?

ok, well, then, have a pleasant evening!
