Installed application size = 1.02 MB (without graphics, icons, splash images etc)
Installed application size = 768 kb (with graphics, icons, splash images etc)
Note that the installed sizes of the applications vary. The first one is larger even though I never used any graphics for icons, splash screens or other bits. The Flash Builder 4.5 Burrito application has a larger installer, however on the Google Nexus 1 disk, the installed application is only 768 kb, of which roughly 398 kb is images alone coupled with 230 kb of icons! The Hero framework rocks! Here is a screenshot.
Last thoughts? I am now addicted to mobile development! Adobe Flash Builder 4.5 rocks (even though it is a preview and somewhat "beta"). The most beautiful thing is that I can use 95% of my code for a desktop application too.
Try it for yourself. Download the Flash Builder 4.5 preview from http://labs.adobe.com
I will post a video of this whole process very shortly on this blog.
Peace, love and may your code compile on the first try!
