This is the second part of a series of posts detailing the migration of a Flex 3 AIR 2.0 application to Flex 4.

For AIR 2.0 release on labs.adobe.com I created a Microphone Example application showcasing the new feature that allows access to raw microphone data in Flash Player 10.1 and AIR 2.0. This application is a custom chrome AIR application that uses a lot of CSS and embedding of assets, both fonts and images.

I am not a networking guru so there is a lot of room for improvement on this idea. What I wanted to do was use the new AIR 2.0 DatagramSocket feature to try and find an IP printer on my home network. I wanted to do this with no knowledge of the printers ip address or my local computers ip address for that matter. I didn’t want to try and guess on ip addresses or loop over an ip block. This is where Zeroconf and mDNS, aka Bonjour, comes...

I have been playing with optimization techniques for building applications targeted for constrained devices. While at 360Flex and talking about some of the memory size issues around getting bitmap assets into ActionScript applications Brian Diette provide a tidbit which was quite useful. In my original finding and understanding of getting assets into a SWF there was two ways. Using the [Embed] metadata with mxmlc to embed assets directly into...
