Hey Jonathan,

Um, "Jonas" is what I typically trigger to.

Your app seems successful and to work the way you want so I wouldn't
dare tell I can do best :D

My pleasure. The 4.6x average rating seems to have earned me a Nexus, so I guess it is doing OK.

If your users can try to call for 30 000 entries and generate a OOM
then you are not doing your job.
And since I'm mean and everything I'm going to the market right now to
download your app and asks for the 30 000 items and then post a "your
app sucks"/One star rating :D
I'm just kidding I wouldn't do that :D

It would take you a while. My testing indicates that I can get to about 600 in a minute (fetching 20 items each time the user reaches the end of the list). I seriously doubt anyone can be bothered to spend enough time scrolling to reach the end of the 30000+ list or OOM (whichever comes first). That would take you about an hour unless you are significantly quicker than I am. Note that I will catch the crash dump automatically so I WILL know if actually did it! ;-) Hence, I know that it has not happened yet (but the map has run out of memory a few times - AFAIK, there is nothing I can do about that).

No need for Flurry&CO - it is trivial to see in the web service log.

And so what is the result ? How many of your users scroll down the 500
item mark ?

Excluding myself? ;-) Exceedingly few. As the list is sorted in rank order by default most users find what they are looking for even in the very first batch. (Statistics guys would probably claim that this will skew the statistics so that the top ranked become even higher ranked, but I can't say I'm particlularly bothered about that.)

What is your app by the way ?

The app is Prisjakt: http://www.appbrain.com/app/se.petersson.prisjakt

There is a demo of it running on the X10 (created by Sony Ericsson themselves actually): http://www.youtube.com/watch?v=e9l7eXhcnvM

However, please note that the application data is only for products sold in Sweden, so therefore the actual interface is only in Swedish - the applications isn't very useful elsewhere.

                        Best / Jonas
