Getting ready for AIR 1.5 and Flex 3.2

david_deraedt — Sun, 10/19/2008 – 12:50

With flashplayer10 out in the wild, it’s only a matter of days before the release of both FlexBuilder 3.2 and AIR 1.5 -aka Cosmo (nightly builds are already available). Although we probably shouldn’t expect much besides the FP10 upgrade, it’s still pretty exciting news. I don’t know about you, but I still haven’t compiled any application for this player just yet. I didn’t want to bother tweaking my development environment, and just prefered to wait. Now, I must say I’m getting impatient… Here are some thoughts about what we can expect from these Read More

What makes a flex app big in size ??

Generally what makes a flex app big in size
1.Try to load your assets (images/animations) at runtime.
2. Try not to embed fonts. If you don’t really need a special font, or advanced anti-aliasing and you are not applying any effects and transformations (alpha, rotation etc.) to your text, you don’t need to embed fonts.
3.Another important concept is that of modular applications. Here are the docs:
http://livedocs.adobe.com/flex/3/html/help.html?content=modular_1.html
4.make sure you are looking at a “production” compile and not a debug compile.  There is significant difference in swf size.
5.not forget the Runtime Shared Libraries.  If you can offload the Flex Framework into and RSL that will significantly decrease your swf’s size.  The initial load will be the full 1mb, unless the user has been to another site that loaded the RSLs already into the flash player cache.  Every subsequent load will be reduced by about 500kb if you’re using the full flex framework.
