This is my second time making and game and I want to make sure that I fit under 50 mbs. So far my plan is to fit all the games artwork into two 2048x2048 sprite sheets. I tested a empty unity3d project and when the apk was made it was 19 035 KB of size. Where does this overhead come from and how can I reduce it?
This is not a duplicate question of this one. I'm asking why building a completely empty project results in a apk with a size of 19 MB. Does this mean that I have limit my assets to 30 MB so that the complete app will be less than 50 or is there a way to strip some of those initial 19 MB.
