Well, one thing I discovered by developing with Corona is that the builds gets larger than they are supposed to be due to some Corona libraries included to the app/game even when they are not requested in the code. The majory Android devices users suffer when it comes to large applications because of the lack of hard drive/SD memory.
My doubt is the following: Is there a way to download the app/game files from the Cloud as well as the majory of Android developers of large games do and keep the files untouchable by the app/game users?
