Apple iOS prereleases support more devices than Android, which only supports two: Nexus 5 and 7 (unsure if the first generation of Nexus 7 is supported).

It's fairly common to test your Android apps against a multitude of devices. There were times I had more than 5 different smartphones on my desk.

So, you're reaffirming what I said (i.e. Google didn't do a good job) as their preview works only on two devices - their own Nexus 5 and 7 (not even on Nexus 10 or Nexus 7 LTE; it's safe to assume that the first generation of Nexus 7 is not supported either).
