Jelly Bean was announced at Google I/O just recently, but a posting from Google's Android open source guru, Jean-Baptiste Queru has confirmed that Android 4.1 is hitting the Android Open Source Project (AOSP) repository right now. Time for the developers among you to update your clients to get all the official bits.


This release will be tagged as android-4.1.1_r1 in AOSP. While the source is going live now, the full proprietary binaries for Google-blessed devices won't be rolled out until later. Google plans to directly support the Nexus 7, Galaxy Nexus, Nexus S, and Xoom through AOSP. Be aware that the addition of the Jelly Bean code to AOSP doesn't mean any OTA updates are on the way. This just means anyone can download the full source to begin work.

The full source code can be downloaded as soon as it's done uploading and replicating (estimated to be about 6PM PDT) at this link, and the manifest is here. The Nexus system images from I/O have been floating around for modding recently, but this will accelerate things greatly. AOSP-based ROMs like Cyanogen and AOKP will be able to start working with the Jelly Bean code. The folks on the CyanogenMod team are already downloading the code, and will begin early work on ROMs shortly. Get ready for the custom ROMs to flow.

    Woot!!! Now the work on JB for AOSP-based ROMs like CyanogenMod can finally start.

          Arent they even finished with ICS yet? How could they already start with JB?

          • József Király

            JB and ICS aren't that different than ICS and GB was. Pulling over the ICS changes to JB will be quick and mostly painless. Except for a few little quirks where the customizers have to manually patch up the sources.

          • GazaIan

            They're not even done with CM7. They said they're looking to do one stable release of CM9 and end it there, and move on to CM10. Any CM9 device will be bumped up to CM10.

    Brb changing my pants.

      Grab me a pair too, I don't wanna leave just yet.

      • atpiggy

        I got it all over my phone. :/

        • alpha55

          So why did you have your pants off in the first place?

          • Nicholas Loomans

            Uh, why do you have pants on???

    I wonder if someone technical can highlight the difficulty of syncing the changes from 4.0.4 > 4.1 if that is possible from todays release of source?

    In other words, what's majorly different :P

    • http://www.androidpolice.com/ Artem Russakovskii

      It's not nearly as difficult as GB -> ICS, but because some of the code was split into multiple parts due to the PDK, it's not going to be a walk in the park either. But expect JB ROMs very-very soon.

        Artem, I didn't see much splitting in the manifests O.o okay, collada was removed, a new compiler-rt popped up (and a few more plus packages). Also, I'm already syncing the tree down, it should be finished in this hour, then the first AOSP builds can begin.

        Just noting: github.com/android already synced in the changes from the official AOSP tree, so if you find the GoogleSource servers slow, this github repo might be helpful.

    Full replication takes about 2 hours, and we're about half-way through.

    6pm PDT seems like a safe bet.


  • BlackGod

    Hold on, I have a Transformer Prime bootloader to unlock

    • FirefighterMatt56

      Pretty sure ASUS is going to update everyone to JB. If they don't, then I guess I will finally have a reason to unlock mine also. Hopefully, it will fix my screen tearing also >_>

    • GazaIan

      ASUS will have updates out for all pretty damn soon, if they continue to be the super boss they are.

  • Lincoln Stewart

    What does this mean to people with Galaxy Nexus that aren't rooted? Will JB be OTA soon?

  • Krzysztof_Bryk

    aokp will not 'work on it' but wait for cm to push nightlies with code bsed on it duh

    • Scott

      What are you talking about? They are a totally seperate codebase. CM merging would not really help them that much. They have their own code to merge into JB.

    This news is the best news I have heard ALL WEEK!

    • http://trevorsullivan.net/ Trevor Sullivan

      Other than the Galaxy Nexus being un-banned, that is.

  • Simon Belmont

    Can't wait for some CM10. Jelly Bean looks great.

    Thanks for the update. Cheers.

  • http://www.androidpolice.com/ Artem Russakovskii

    Deployment and replication have completed, you can now sync AOSP.

    My repo sync is all done :)

  • jellymelly

    So is this the final build which will be rolling out as an OTA? Or is this code just the Dev preview of JB handed out at Google IO?

    • jellymelly

      downvotes, really?? It's just a question!??

      • pikachubro

        that's life

        • Ravengenocide

          Or: that's internet.

  • Bariman43

    YESSSS. AOKP JB/CM10 here we come! It was hard readjusting to Stock Android, but now I can get all of those wonderful AOKP features back!
