Android Dev Rookie ?'s

Hi there,
I have never published to Android and as such have a few questions, for now tho, just one.

In my game, as built for iOS, I know there are a clearly defined number of screen resolution possibilities. How do I know this for Android? Are there not a bunch of random types? Should I just look at the major models and base it on that?

Thanks

Basically with Android device can have any screen resolution. So you have to make GUI and gameplay in such a way that it works with device that has aspect ratio between 4:3 and 2:1
