Good news everyone!

-The source code for 4.2 is being pushed to AOSP right now. Look for
it under the name "android-4.2_r1" once the replication completes. The
matching development branch (for CTS contributions) is jb-mr1-dev, and
all the changes are merged into the master branch where platform
contributions are accepted.

-Nexus 10 is now the best choice for AOSP work on 4.2. Everything
except the GPU code is Open Source, and the only proprietary binaries
besides the GPU libraries are firmware files that get loaded into the
various peripheral chips. No flagship device so far has been so open,
and no flagship device so far has had that level of AOSP support at
launch.

-Nexus 7 3G isn't supported. We haven't been able to license the GSM
stack for AOSP yet, and without the GSM stack this device doesn't do
more than a plain Nexus 7.

-If AOSP starts pointing toward Nexus 4, you are having a bad problem,
and you will not go to space today (i.e.: there is nothing in AOSP
related to Nexus 4).

-Factory images for the "takju" Galaxy Nexus as well as Nexus 7 (both
variants), Nexus 4 and Nexus 10 are available at
https://developers.google.com/android/nexus/images

-Proprietary binaries to run AOSP on Galaxy Nexus (maguro, toro and
toroplus), Nexus 7 (grouper) and Nexus 10 (manta) are available at
https://developers.google.com/android/nexus/drivers

-There is no support for 4.2 on Nexus S and Xoom. Those devices should
continue using 4.1.2.

I will take care of the kernel sources as soon as everything clears up
on the platform side.

What was that about nexus 4 and aosp?
Nothing for nexus 4 in aosp?
Tell me I'm too sleepy to understand what it was you really meant to say.

To clarify: Nexus 4 is not supported in AOSP at the moment: no source
files, no binaries.

Yakju images will be distributed through the usual location once the
yakju OTA is approved.

Guys:

I reject this justification, unless one truly needs 1GB of RAM to run
the later code.

We killed off the Nexus One earlier than necessary because of a
nonsense flash partitioning issue. Let's not make that mistake again.
While it is true that the GPU in that handset would have provided a
less-than-optimal experience, that's for the end user to conclude for
themselves. Use the user's experience with the underperforming device
to help motivate the demand for new hardware, rather than simply
denying them the utility of their current handsets.

I'm a huge fan of Android and AOSP, and am exceedingly grateful to JBQ
and others for all the hard work that they do. To toss their work
away because certain devices become technically inconvenient for
vendors to support is tragic, makes no engineering sense, and sends
the wrong message to the larger open source AND commercial development
communities.

That part of the discussion is getting off-topic for this thread and
for this forum.

Hi JBQ,

Do you plan to push the git tag "android-sdk-adt_r21" (for ADT r21) to AOSP?

Thanks

I expect that I should be able to do that once everything clears up.
In the meantime, that should essentially be the tip of the tools_r21
branch.

It means that right now you can't build AOSP for either of those
devices in a way that results in a functional device. And that's all
it means.

This should work to build and run an x86 emulator:

There's typically a small gap (hours or days) between the platform
source release and the kernel source release, with the platform
usually coming first (because it's much easier to automate). the
kernel sources have now been available for a little while.

It's got issues. We've got source changes submitted in the kernel
repository, but the prebuilt kernel doesn't seem to work everywhere:
