Google I/O 2011: Android Open Accessory API and Development Kit (ADK)

Mike Lockwood, Erik Gilling, Jeff Brown

You have always been able to connect an Android device to your computer, but until now there was no way for Android applications to interact with other hardware via USB. In this talk we cover new support in Android 3.1 for USB input devices, as well as new APIs for applications to communicate with peripherals via USB. The APIs support both Android powered devices that act as a conventional USB host, and non-host Android devices that communicates with a new class of USB hosts known as "Android USB Accessories". Cool hardware is involved.

I understood the reason provided as bootstrapping/backward compatibility. They seem to be releasing both directions at the same time.

why there isn't any right click support in android ICS

Yeah, I'm kinda wondering why they decided to go that route as well when OTG was supposed to solve this problem. They already have HNP (Host Negotiation Protocol) for USB 2.0 and RSP (Role Swap Protocol) for USB 3.0. I believe that's what the man @ 34:05 was getting at. Lockwood responded with the power issue, but that's exactly why we have HNP/RSP, right? Why undermine a perfectly good existing protocol with proprietary extensions? Sounds like yet another case of NIH syndrome.
