Where can I find a good iPhone/GWT/AppEngine example?

Question

These seem like a great combination--I'd expect to see more on at least GWT/iPhone integration, but there isn't much.

I've looked through the reader example that Google made, but it doesn't seem to take advantage of many of the iPhone features.

I was wondering if anyone knew of a tutorial/resource that showed how to use things like location, orientation, stretch/squeeze and various iPhone-specific controls--as well as integration with services like Google maps.

It would be nice if it also used AppEngine, but that is pretty easy to integrate later if not.

Perhaps I'm asking for too much, but I'd even settle for a very technical blog that focused on these platforms...

Answer 1

Have you looked through the Apple sample code? They wrote example programs for most of the iPhone specific features.

Answer 2

GWT doesn't actually support most mobile browser features (touch events, geolocation, orientation, etc.) out of the box, but the gwt-mobile-webkit project aims to add those features, specifically for the iPhone browser. They even have some demos and example code on their project home page.
