Is android ubuntu based?

[u-noob-tu]

I was watching a video about custom android roms and flashing them to a phone, when the guy on the video went to his settings and showed his kernel version. You can clearly see the word "ubuntu" under the numbers. I knew android is linux based, but is it based off of ubuntu as well? Or did he get a kernel that is in some way related to ubuntu?

Here's the link: http://www.youtube.com/watch?v=g01sEWLcYdk

Certainly not. They do share alot of the same code though as they are both based on the Linux kernel.

At the application level the Android apps mostly use java.

They are not. However Ubuntu will run on some phones like the HD2.

I've not watched the video, but IIRC the user and hostname of the computer on which the kernel for the ROM in question was compiled are listed with the kernel version in settings. I suspect that whoever compiled the kernel for that ROM was using an Ubuntu box with 'ubuntu' as part of their username or hostname strings on their development computer.

No Android is based on the mainline Kernel from kernel.org and not necessarily the Kernel maintained on any one particular distribution..

Ubuntu, however, is the preferred host for Android development but that name shouldn't end up in the Kernel name itself..

When I check the kernel version on my phone, it says

2.6.29.6-Kalim
kalimochoaz@KalimochoAz-HPUbuntu#1

But I know Kalim is working on a Ubuntu computer (and it seems to be a HP)

No it's not, you can develop for Android on all major OSs.

he was saying that ubuntu is the most common/preferred OS for android developement, not that its the only one.

Canonical, I heard, was fairly involved with Google's Android development with the ChromeOS so I would not be surprised if they were tapped too for the Android.

So basically, the only reason "ubuntu" was in the kernel settings is because the maker of that kernel had ubuntu in their username and/or they used an ubuntu box? I never would have guessed that.

Another question: in the same video, the kernel number on the phone is 2.6.32 (if I remember correctly). Is that the Linux kernel 2.6.32 and android just isn't using the newest one? Or has google customized the Linux kernel and given it a different version number?

pretty sure that indicates that they took vanilla 2.6.32 and added their own patches. kind of a half-fork, i suppose you could call it.

good, because it means any good stuff coming out of android kernel development could theoretically be merged if anyone wanted to. i think.

edit: note that we aren't using the newest kernel either. it looks like (http://www.kernel.org/) 2.6.38 is the current stable kernel.

I've compiled my own version of Cyanogenmod 7 a few weeks ago, on Ubuntu, and when you read the kernel version on the Android device it will say Ubuntu.
