Developing Mobile Flash / Flex – Scaling and Zooming

Mobile development with Flash and Flex is a new frontier, full of new adventures and discoveries. Recently I discovered something that might be useful to you. By default the mobile web browser on my Android 2.2 device scales a web page to make more room to display pages typically built for a desktop profile. Here is what a little test mobile Flex app I built looks like: Strange! The width and height are larger than the screen resolution.

Flash Platform and Webinar and Mobile App

Client + Cloud technologies have been quickly evolving and maturing. The combination of Flex and continue to lead the way for next generation Client + Cloud applications. Recently I did a Webinar on The Flash Platform and with Dave Carroll from Salesforce. If you missed it you can watch the recording to see how you can begin developing Client + Cloud apps. Also watch Jeff Douglas demo an offline case management app he built with Flex and Force.

Flex on Android in Flash Player and AIR

This week at the Google I/O conference Adobe announced that a Flash Player 10.1 beta and an Adobe AIR prerelease are now available for Android devices. This is really exciting news for those of us building apps on the Flash Platform because now we can begin building apps in Flex for these mobile devices (and many others coming soon). Take a look a some of the quick demos I’ve built with Flex running on Android in Flash Player and AIR:

Flex Performance on Mobile Devices

This past weekend I spent an hour optimizing the Flex 4 scrolling demo that I posted last week. The original demo was intended to show how to hook up touch events to the Flex 4 List / DataGroup controls. This new version adds some optimizations for the touch event handling and adds the kinetic flick behavior. Check it out and let me know what you think: I’ve posted the code for this second version of the touch scrolling demo.

Flex 4 List Scrolling on Android with Flash Player 10.1

UPDATE 1: The first version of this demo was intended to show how to hook up touch events to the Flex 4 List / DataGroup controls. I’ve posted a new version that adds some optimizations for the touch event handling and adds the kinetic flick behavior. One of the challenges of running existing web content on mobile devices is that user interactions differ between mediums. For instance, on a normal computer with a mouse, scrolling though lists is often done by clicking on scroll bars or mouse wheels.

Flex Apps on Mobile Devices

This week at Mobile World Congress Adobe has been showing off Flash Player 10.1 on a variety of mobile devices. Last week I received Google’s Nexus One device with an early version of Flash Player 10.1 on it. Here is a video I shot today showing how Flex applications can run on mobile devices with Flash Player 10.1 and how existing applications can be tweaked for the size constraints of these devices.

Rich-Client Misconceptions & Adobe’s Open Screen Project

Artima recently posted two interviews with me which relate to Flex. First is an interview about Adobe’s Open Screen Project. The second is called Rich-Client Misconceptions. Also Bruce Eckel recently posted a very interesting article on Artima called “Concurrency with Python, Twisted, and Flex”. Let me know what you think about those.

The Open Web: Now Sexier and Smaller

In the past Open Web proponents have criticized Flash and Flex because the SWF specification - while being published and publicly available - limited what readers could do with the specification. More specifically the agreement to view the specification required that readers not build programs that would run SWF files. The intentions behind this were good - Adobe does not want Flash to have inconsistent and incompatible implementations. Today Adobe Systems has announced that they are removing those restrictions on the SWF and FLV specifications!

Tamarin-Tracing: Mozilla’s New VM for ECMAScript 4

[Update: QVM was an internal Adobe codename. The new VM’s name seems to be “Tamarin-Tracing”. For more info on this new VM read the announcement by Edwin Smith. Edwin doesn’t explicitly state that the VM is for mobile devices but it is hinted at. However the research paper that Edwin references does state that this tracing type of VM is good for mobile devices.] The mobile space has been heating up lately with Apple’s iPhone, Google’s Android, and Sun’s JavaFX Mobile.
