The apk file is already compressed in itself and way smaller than all other versions. Putting it in a zip container is not really making it any smaller I'm afraid.
What issue do you get? Is there an error message of some sort?

Are you trying to download directly onto the phone? Maybe try to download on a PC first and move it to the phone afterwards.
Else you could try to download it from MEGA: https://mega.nz/#F!CpQXwBDS!wwZlWRrPWoGzZX5h0-MlRQ
