In your AIR Android Settings there is a spot at the bottom of the "general" tab called "Included Files". You can hit the + button and select your swf file you want to include. Is that what you are looking for?
I also was wondering the same thing, I believe the included files is what I need, how would you reference the included files in actionscript?
They should be able to be referenced as if they were in the root of the package. So if you have test.swf included you would simply reference as that without a path name. If they are in a folder you would reference the path through that folder of course.
