I have a simple one-screen Flex app that I'm using to test out the DatagramSocket class. Everything's working okay but when I build the application on Mac OS as a captive runtime the resulting app package is 169MB. This seems huge considering that there are no graphics, videos, sounds or other heavy assets in my application. The Windows version when bundled as a captive runtime is 40.1MB.
I'm compiling using the AIR 3.5 SDK on Mac OS 10.7.5. I have an Ant task that I'm using to create the captive runtime but I've also used Flash Builder 4.6's Export Release Build command and adt via the command line. In all cases I get a massive app on Mac OS.
Is this size normal? Is there anything I can do to get it more in line with the Windows version?
