I'm new to Air. I'd like my application to be pretty light so it loads quickly. So i'd like to place all my assets (XML files, graphics, etc) outside from the main Air file and when the main Air file is loaded into memory, I'd like it to load in the asset files at runtime.
So how do I go about telling Flash builder to save my asset files locally when it packages my Air Application and also ensure I can access these files while debudding my application?
I recently worked with this same problem. The answer is to use the adt command-line tool that comes with the SDK to explicitly include everything you want into your .air package.
Also, I haven't tried this tool, but it sounds promising:
if you're using flash, the air publish settings have a section (general) that allows you to designate files/folders (included files) to include with your air app.
