Paranoid Android made headlines last week when it announced a new take on mutitasking called Halo. While the feature wasn't available for user testing at the time, the team has now pushed out early alpha builds for the Nexus 4, Nexus 7, Nexus 7 3G, GSM Galaxy Nexus, and Oppo Find 5.

This is still a "very early build" of the ROM, so expect bugs, crashes, and other odd side-effects that come along with using alpha software; in other words, don't expect to use this as a daily driver.

Still, the PA team claims to be about halfway through its Halo implementation, as it has broken integration into three phases: rewriting the framework, getting Halo performing its basic functions, and allowing notification-switching directly through the Halo interface. The first phase has been completed at this point, and the second phase is said to be halfway finished. Once that's complete, the third phase will begin.

If you'd like to give Halo a try in its current state, head over to Paranoid Android's Google+ posting for build and GApp downloads.

Update: The PA team provided this handy FAQ.

    Still not understanding all the hype from this feature. I don't see the difference between switching to an app via the notification pull-down, and loading a laughably-squished version of the app on top of what I'm doing.

    This is really only useful for when gaming or watching videos or otherwise in a full-screen app.

    It certainly isn't as groundbreaking as the guy in the video claims, and it certainly isn't leaps and bounds more useful than Samsung's MultiWindow (which I find pretty useless as well, to be honest).

      you have just answered your own question.

    • troph

      You'll have to use it to understand it. Samsung's Multi-Window was a gimmick that most people will agree they never use. Try it out and you'll see.

      simple noob, the greasted feacture of paranoid andorid is the PIE mode, em FULLSCREEN!!, no statusbar, no nav buttons, sop halo is a great addiction to it, look cool,, its a new way to multitasking.

      • enomele

        So hard to read.

    • Ivan Myring

      I agree that its not as good as Sammy's multi window, but it still kicks arse

    • kyle duncan

      Use it for a week and then you will get it. Full screen pie mode with halo. Then post your opinion.

    Got it in yday's nightly. I'm on a Galaxy Nexus, loved the feature and considering it's still in its early days, it's just, wow...

  • troph

    Using it now on my Nex4. I think they are on to something with this. I see it as the next big step in mobile-- part of taking it towards multifunction.

    This is gonna be fantastic!
    A lot of people, including myself, were skeptical about Facebook Messenger's ChatHeads. And then after using them for a day, they're the best thing ever!
    I can't wait until a build for the N2 goes live.

  • RitishOemraw

    Google should build this into android at some point.
    Just wish I could have Halo as a standalone app APK.....but that won't happen sadly :(

    y u no Nexus10?! This is ideal for something of the N10's size.

  • vivek

    can someone please put in the link of paranoid android for gnex. thanx in advance.

  • EH101

    This seems to be nothing more than a new way to do quick reply, not multiwindow, which makes it fairly useless. I can still see PIE being useful to get back all the wasted space of the navigation bar, but the notification bar needs to stay. This certainly isn't a good or full replacement. As such, Google will never implement this into stock Android.

  • Gabe Maier

    What launcher/icons is that in the video?

  • Freak4Dell

    I was kind of looking forward to it when it was announced, but now that I'm seeing how it works, I'm not into it. It's not really multitasking in any true sense of the word. Samsung's Multi-Window is more of what I want, I guess.

  • GoogFan

    Please Google hire all the devs behind this (and PA in general)! Because independent means freedom but also lack of stability, and availability. This and other PIE stuff would make a killer feature for future versions of android! I know many of you guys don't see the potencial, because it's presented on a phone, but just imagine a tablet... whoah! ;)
