mobile android app size question?

hello im making a mobile app with unity3d and i was wondering i have an almost empty project and i built it and ran it on my android device and the app size on the device was 14 megabytes for a practically empty project, i think i had 2 - 256X512 images in there thats it, what im wondering is what does it put in the APK file like a unity player or how does that work? 14 MB seems pretty steep dont you think

Everything the Unity engine might need has to be in that apk. I read somewhere thats about 6mb, but i believe it’s more than that. If you own the pro version for android, you can strip out anything thats not needed, but othwerwise you can’t really do something about the apk size.

My apk is about 19mb and i only have assets worth ~6mb in the project. I guess we have to live with it, or buy the pro version.
