Well, Danger, Inc. had products before some people splintered off to form Android, so it's not at all shocking to consider they had a homegrown embedded kernel and brought up a JVM on it. It's also not really shocking to speculate that experiences with that could have influenced the team of ex-Danger people when they later decided to build Android on Linux. Whether or not this Quora user has any insider insight on this, I don't know. Probably they could not have used Danger code, since it was owned by someone else. But you might say they replicated a similar design.
