I have an app that only have "TableView" library and shows a list of sounds, sounds directory is 7,xxMB and the size of other files isn't more than 50kb

My Coronas project size in a PC directory:
7,xxMB(directory with lua files, some images and sounds)

Later, when I generate the APK file installation, the size of APK file is:
12,xxMB

Why is the reason of this increase?

But, there are more, when I install app and after the first time that I use the app I can see that the size increase a lot!

App installed: 15,xxMB
Data: 3,xxMB

TOTAL: 18,xxMB

I don't understand why the reason of this increase.
Anybody can help me? Thanks !!

Again sorry for my bad english :P
(I don't use translator, I don't like it)

Gracias :)

when you build for apk ansca adding some libraries like socialintegration,physics,credits and some images needed by them so size increases

apk is one type of zip format may be some of the things needs to be extract from this in order to run app (not everything) and may be you are also putting some things in documents directory after run like db... so again increase
