Of course there was a SDK, how else would developers make apps for the platform? Are you implying Google was planning an app store back then? The video doesn't speak of it. Or are you stating that date as a start of Android? In which case, you can go back way further in time.

The first commercial Android phone, the T-Mobile G1, went on sale on October 22, 2008. It had a small screen, a hardware keyboard, and a clunky UI reminiscent of Symbian. I doubt Android was on Apple's radar then, let alone back in 2007.
