Hmm, that would probably be easier for me. I'd shied away from anything like that though thinking that it would be a pain for users?
not really, the only catch on my end has been getting access to the folder sometimes, but most of the droid versions have a secondary folder to get around the permission problem.
With that admitted, doing it that way would require the user to put another archive in every blue moon and thats about it. Well that and the initial install. The rest of the time it would just be apks as normal
