Keep in mind that the Android SDK has quite a few features that allow you to create liquid layouts that will work fairly well on most device sizes, as precisely because the Android OS comes on a great variety of hardware, this problem had to be addressed early on, while on iOS every time a new screen size/pixel density comes along you have to create an all new view.

I'll acknowledge that many times you have to fiddle a bit to make sure that your Android view works well on a variety of screens, but usually you can target between 3 and 4 layouts and have a usable UI for all devices from 10" tablets all the way down to small feature phones.
