Can somebody help with modern combat 4

[AndroidS3]

Well I'm being a bit of a tight arse here but I don't want to pay a fiver just for this game, I've gone onto the internet and installed the .apk free but you need the SD files aswell, but it's 1.3GB+ and it's taking hours to download. Does anyone know how to install through game just using the .apk without have to manually install the sd files?
