I’ve had the same experience attempting to deploy to a first-gen Nexus 7 (an aging piece of hardware now).
Android deployment is still a bit rough. Right now the devices with the best support are the Galaxy S4 and the Nexus 5, and I expect support for other high-end devices won’t be far behind. I’d expect support for slightly older or mid-range devices will be added eventually (as much as hardware capability allows), but newer devices are likely the priority.
