Developing AS3 for desktop and Android Smartphone coexistance

Question

I have recently built a knowledge management web app which runs unchanged on desktop browsers and Flash on Android. The client side is written 100% in Flash AS3 which is unusual, so I thought I would share a couple of learning’s from the Android aspects of this development.
Overall it was remarkably straight forward after I worked out the right architecture. The trick is for every aspect of the code to be aware of the screen size and capabilities of the device being used. There is no point in trying to view large diagrams on a small screen, or just scale them down; you need to customise the display appropriately for the different screen size. In my case I changed display formats when the screen width is larger than 600pixels. You also need to make sure that the click areas are bigger when used on smaller screens
I used Flash CS5 for the development, but the only feature that I used that is not in CS4 was to find out whether the screen was touch enabled so I could adjust the button sizes. Click events and mouse_over events work fine with Flash on Android, so for simple interactions it is not necessary to use all the new CS5 touch events. The only problem I encountered was getting the HTML right on Android (e.g. viewports). This area still has a little work to be done.
Ok, a 100% Flash web application is a little unusual, but I wanted portability and my last programming was 20 years ago. AS3 was easy to learn using Google searches and these forums. The back end is PHP and MySql
You can find the app at http://www.line-manager.com/mobile.html . It was tested on a real Nexus One. The virtual Nexus One on Device Central was not much use as it said the Nexus One did not have a touch display!  There are still a few issues to resolve but it’s ready for “Beta”. Performance appears fine on 3G and Wiifi.

Answer 1

Explain your credentials. Do you know AS2 or AS3 programming. Familiar with AIR SDK? Flex SDK? Flash Professional? Flash Builder? FDT + Eclipse?
Where you start greatly determines the recommendation. If none of the above is anything you would consider yourself to be familiar with, and books are your thing, you're a half dozen or more books from where you need to be.
