Yeah, DangerOS doesn't exist. This person's answer is nonsense, not sure why it's being highlighted here. The other answers are equally absurd.

https://en.wikipedia.org/wiki/Danger_Hiptop#Software https://en.wikipedia.org/wiki/Danger_Hiptop#Software What operating system and Java Virtual Machine (JVM) are you using? Danger has written its own operating system and JVM for the hiptop. The Operating system has preemptive multitasking and a soft real-time scheduler, and it has been tuned specifically for running our JVM. All end-user applications are written in Java, as is the overwhelming majority of the high-level operating system. Arguably, Danger has the premiere "Java Operating System" on the market today. https://web.archive.org/web/20100405231610/http://developer.danger.com/site/faq#q3 https://web.archive.org/web/20100405231610/http://developer....

Getting online answers absolutely correct and above nitpick could be a full-time job. From a historical development perspective, the post is interesting and factually describes the roots of Android. There's probably much more to the story though.

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.
