Ubuntu 12.04

[Johan Ramm-Ericson]

Hi,

I'm just curious to know if there is any information on if and when
the Android team at Google will be moving to Ubuntu 12.04 as base
environment?

Thanks and Best Regards,
Johan

[Akash Ramani]

There is no official info, but 12.04 is going to be LTS right?

I would definitely think that they would make the jump

[Jean-Baptiste Queru]

I'm guessing that the timeframe would be measured in months after the
Ubuntu release, though it's hard to tell as it depends on many
factors.

I'm guessing that there's a possibility that the next Android release
(the J release) will have been developed primarily under 10.04 but
will be buildable under 12.04. That way, we won't have to switch our
workstations in the middle of development, but we'll be able to switch
as soon as the bulk of the J work is done and keep the ability to work
on that release for maintenance.

We're aware that Ubuntu only supports overlapping desktop LTS releases
for 1 year at a time, which is actually quite short now that the
Android release schedule has been slowing down, and that's why we're
keeping a close eye on things.

12.04 is planned to be a super-LTS, lasting longer than the usual LTS
https://wiki.ubuntu.com/LTS

That being said, I can't really speculate on when or how long we will
support building on it.

Well, cool, I didn't know that. That'll be very useful the next time
around, we won't be quite as constrained by time.

The next major release will support building on a 12.04 host.

Right now, the AOSP master builds fine on 12.04, and we already have
instructions on setting up a machine for that (it's a bit more complex
than on 10.04, but not much more).

Interesting!
I assume 10.04 will still be supported. But both should be considered well tested and supported then?

Is that with Sun JDK still or does it include OpenJDK as well?

I expect that 10.04 will remain the preferred option (it's the one
we're still mostly using internally, because older versions of Android
don't build on 12.04), but I expect that doing a full development
cycle on 12.04 wouldn't be an issue.

Sun JDK 6 will definitely be the only supported JDK.

We set up a build for ICS under Ubuntu 12.04 for our rowboat based
custom board.
Maybe it will help someone setting up his environment:

Woah, take a deep breath before attacking people on old data.

Jelly Bean (all variants) has been developed on a mix of 10.04 and 12.04, and there should be no difficulties building any of its variants on 12.04. Google's official builds come from 10.04 servers, but the LTS support cycle for servers is much longer so you have a few more years ahead. Since Jelly Bean also carries its own host gcc, differences between 10.04 and 12.04 should be minimal anyway, and I don't expect much trouble building official Jelly Bean binaries on a 12.04 host.

The latest development branches of older versions all the way back to Froyo are also expected to be buildable on 12.04. I think I'd know, I've done the fixes and backports myself.

Dear Jean-Baptiste, et al.,

I know this thread is old, but it's not really resolved yet.  In this day and age, it is irresponsible to operate on and "end-of-life" platform.

Ubuntu 10.04 LTS Desktop is no longer supported by Canonical after May 9, 2013:  https://lists.ubuntu.com/archives/ubuntu-announce/2013-March/000169.html .

This may put people that care about running a supportable OS in uncomfortable positions such as having to "wrap" a supportable 10.04 LTS build environment as a "sand-boxed" Virtual Machine within a supported host OS. What a nightmare!

Please tell me that AOSP at least has a plan to move beyond Ubuntu 10.04 LTS being the only supported build environment!

There was a similar situation with OS X a while ago which was resolved with patches from the community. The rule seems to be to upgrade when there's a technical reason rather than an administrative non-technical one.

That's good news! The documentation web pages and this thread seemed to be a little heavy on the "use 10.04 at your own risk."

[Jean-Baptiste Queru]

Yup. Technically, that's accurate of any release. If you're building JB, the extra risk is probably tiny, potentially negligible in the noise. For older releases, it's most probably larger.

For gingerbread, I think that all you need is commit 9b19b93a5b0018414784cfdc070b462ea65451d8 in frameworks/base

JBQ,

Thanks for your work. I would like to ask if you could explain what should be done to build older releases on Ubuntu 12.04 (or point in the code where to find these changes). The reason I ask about this is that we have a fork of Android Gingerbread and I want to get it compiled on Ubuntu 12.04.

[Jean-Baptiste Queru]

Actually, you also need d93b236e4e3e6a8edb912507b9d66e5fad46f07f in build

[Happy]

Is there a similar back-port commit for ICS 4.0.3 or 4.0.4 on 12.04?
