2006 - Jasper S20 with SavaJe OS gets presented at Java ONE
2006 - End of the year, SavaJe fails to gain another round of investment, in spite of the successful reception at Java ONE
2007 - April, Sun public announcement to buy SavaJe assets
2007 - November, Open Handset Alliance is created
2008 - November, HTC Dream gets released as the very first Android device. The initial architecture diagrams have a certain resemblance with SavaJe ones.
The OS that came to be Android started in 2003, was initially based in JavaScript, had lots of time to inspire on Java stacks after they pivoted to Java and were eventually bought by Google.
Only after SavaJe was no longer around, it became public what Google was up to regarding their mobile OS strategy.
Why are you comparing the date of SavaJe's being acquired, with the date of Android being actually released or gaining third party external hardware partners? Apples and apples would be Google's acquisition of Android in 2005 vs. Sun's acquisition of SavaJe's in 2007. And even then, Google acquired the actual devs too, whereas Sun only acquired the code and IP.
And Android is way more a rip off of Palm than SavaJe. All of the interesting things it does (the intent system, the capability based IPC, the battery friendly process lifecycle model, etc.) clearly descend from Palm (which isn't a surprise given that's where Dianne Hackborn cut her teeth).
Sun buying SavaJe was pretty clearly a response to Android, so it's pretty disingenuous to say that Android killed SavaJe.
