You can transfer your Kim Kardashian: Hollywood game from an iOS device to an Android device and vice versa. However, you can only connect with friends in the game who play on the same platform as you.
 
For example, let’s say you previously played on an iOS device with Facebook friends who have iOS devices. When you transfer your game to an Android device, you will now be able to connect with Facebook friends who play on Android devices only and vice versa.
