You know the Android codenames, right? Starting with Android 1.5, they're alphabetical snacks - Cupcake, Donut, Éclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. But what about before 1.5? What were those called? And why did they start with C? We've got real answers from real Googlers.

Wikipedia's Android Version History is a pretty awesome article, but, as of a few days ago, it was erroneously calling 1.0 and 1.1 "Astro" and "Bender." We had never heard of this, and there wasn't a good source attached to it, so we took to G+ to set the record straight. Luckily for us, Android Engineers Jean-Baptiste Queru, Dianne Hackborn, and Romain Guy chimed in with historical accounts of Android's sugary pseudonyms.

As with any historical accounts, stories are going to differ slightly, but everyone agrees that the delicious code names didn't start with Cupcake, Android 1.1 was known as "Petit Four." After hearing that and doing some Googling, you'll find it even says so on the official Android Platform Overview page.

As for 1.0, the answer may be boring, but JBQ says "Android 1.0 didn't have a codename at all." Dianne Hackborn says she doesn't remember the code name of 1.0, and suggests "maybe it was just 'OMG are we going to survive this?'"

Pre-1.0, things start to get less user-friendly, with JBQ saying:

When I started in Nov 2007, the scheme was around "milestone" builds, and milestones m3 and m5 ended up being used for preview SDKs. After that, we had weekly builds (e.g. WB13 was the build for the 13th week of 2008), and after that we had test cycles during which we were incorporating external feedback (e.g. TC3 was the third such cycle).

There were no codenames at any time from where I started until the beginning of the work on post-1.0 tasks.

And, sure enough, if we take a look at the official SDK archives, you'll see versions like "m3-rc20a," "m3-rc37a," "m5-rc14."


Left: m3-rc20a | Right: m5-rc15

These "milestone" builds are all pre-1.0 builds of Android that look nothing like the 1.0 build we saw ship in the G1. M3 looks like a Blackberry OS, and M5 has 4 apps, no app drawer, and no usable desktop.

If you think names like "m3-rc37a" sound hard to keep track of, you aren't the only one who feels that way, with JBQ explaining that this murkiness would later be the impetus for a new build numbering system.

In early 2009, there was a lot of confusion with the build numbers because people didn't use the full build numbers, saying "rc30" without saying whether they were talking about 1.0-rc30 or 1.1-rc30 (and there were many more variants inside Google). That's when we decided to switch to a new scheme for build numbers, the one that we're now using. The first build under that scheme might have been CRA29.

That's when we realized that having C for the third release was a good idea (even though it was really the fourth release as there had actually been two versions of 1.0), and when we decided to pick codenames alphabetically after that.

And there you have the reason they started with "C." It was the third release, so "C" just seemed like a good idea. JBQ also says that "Donut was the first one where the name was made to explicitly start with a letter in alphabetical order." So it sounds like after realizing Cupcake and 3 went together well, they settled on alphabetical snacks.

So what about these "Astro" and "Bender" names from Wikipedia? Romain Guy says of the Wikipedia article "They link to a talk I gave were I mentioned Astro and Bender but I never said they were 1.0 and 1.1" Dianne Hackborn attaches them to the milestone builds, saying:

Astro Boy and Bender were definitely code names that were tagged on some milestones with plans for using a robot theme, but these may have been pre-1.0 milestones, or plans-that-changed for after 1.0.

And in the G+ post for this post (we are getting seriously recursive here), Dianne also adds that:

The early code name was Astro Boy, not Astro.  The plan was to use code names that were fictional robots, and we were going to do them in alphabetical order.  As things went on, plans changed, and those milestones were modified, and at some point we ended up with 1.1 being Petit Four because our PM liked tasty treats.  We then went with that, but went back to doing them in alphabetical order.

So Astro Boy and Bender were real, but they went with the super-early milestone builds, similar to what's pictured above. The full timeline goes like this:

  • Android milestone builds (with Astro Boy and Bender floating around in here somewhere)
  • Android 1.0 (No codename)
  • Android 1.1 - Petit Four
  • Android 1.5 - Cupcake
  • Android 1.6 - Donut
  • Android 2.0 - Éclair
  • Android 2.1 - Éclair
  • Android 2.2 - Froyo
  • Android 2.3 - Gingerbread
  • Android 3.0 - Honeycomb
  • Android 4.0 - Ice Cream Sandwich
  • Android 4.1 - Jelly Bean

So there you go. An actual codename history, and not this silly "1.0 Astro/1.1 Bender" stuff that people on the internet are endlessly repeating. Don't believe everything you read.

    So Android looked remarkably like BlackBerry--until Eric Schmidt joined the Apple board...

    • Wayne Morrison

      it actually looks a lot more like the T Mobile Dash on Windows Mobile Than it does a BlackBerry.

    • Josh Brown

      Both designs were planned and were done concurrently. Around the m5 point it became pretty clear that the non-touch prototypes wouldn't be viable, but even today Android totally supports non-touch devices (which is partly why there was an emphasis on making sure d-pad navigation works until recently). I'm not certain of this, but I'd imagine the non-touch portion was done earlier since it would be easier to build and test, so I wouldn't be surprised if m3 was predominantly non-touch.

      From the very beginning Android was designed to be very flexible from a hardware standpoint. They wanted to be as future-compatible as possible, and I think Android's resource management system really shows that. I remember reading an article where Diane Hackborn described some of the lessons learned from her time at Palm, where they wanted to change screen sizes and densities, but were very limited in their options. They had to be exactly 2x density to avoid rounding issues, they couldn't change the size without filling that space in legacy apps, etc. (hmm... sound similar to a particular fruity OS?).

      Android was designed to get around all of that. Touch input was already something that had been seen coming (and had already been done with Palm, Windows Mobile, etc), and Android needed to support that even before the iPhone became popular. The only thing that changed was the market. No one wanted non-touch devices anymore, so the focus for manufacturers became touch devices.

    • blunden

      That's a tired argument that doesn't really have that much basis in facts. It is based on just one of the type of prototype devices used and it contradicts what you find if you actually run the pre-1.0 builds that are available.

  • Melvin Blokhuijzen

    Really nice read. Thanks for clearing everything up and for the great article!

          No, Pumpkin Pie, definitely Pumpkin Pie.

          Either way, if it is one of those pies, they should release it right around Thanksgiving.

          Now I'm hungry. :(

          • navjot

            It just so happens that, that particular release will be an end of the year release (like ICS) rather than an Q1/Q2 release (like JB)

    I think they should switch to naming the versions after famous robots. It is ANDROID after all.

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

      Like they're going to suddenly break the paradigm after 3-4 years and switch to something different in the middle of the alphabet.

      • http://twitter.com/LV2355 Laurentiu

        Maybe after 8-15 years (1 or 2 versions are released every year) after the alphabet dessert reached Z they could start with alphabet robots.

        • Greg Bissell

          No they can't because they are trademarked

    • ari_free

      Only if they are also tasty.

    I always assumed it was alpha and beta, then came the release of cupcake, good article

  • http://www.facebook.com/profile.php?id=100000003999549 Mike Harris

    I guess I'm the only one who thought the "A" and "B" stood for "Alpha" and "Beta".

      I always thought that too

    • http://www.google.com/profiles/MetalMessiah78 José Gómez

      I could have sworn I read somewhere that Andy Rubin was asked at one the Google I/O's what A and B stood for, and he answered Alpha and Beta. I wish I remembered where I read it.

    funny.. you would think that someone would bother to ask me?

  • fadilkarim

    So what's after Z?:o

    • Campan Flaviu

      'a' again?

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

        AA, like in Excel. Aardvark Jelly?

    • technohead95

      With Google slowing down releases (and keeping the same name for multiple minor version number updates), I doubt they'll even get to Z. Every company, product or any other big thing, will eventually have it's downfall. Nothing will last forever. Assuming they use one letter per year, then they'd have another 16 years to get to Z. As great as Android is. I doubt it'll last that long.

      • Memphis May [S]unjay

        You're right, iOS is already at the peak of it's downfall.

  • http://www.geeksonhugs.com/ W. Anthony Tanas

    Ha! OMG that was me! I hate to admit this bit I'm the very person who put Astro and Bender in the Wikipedia article! Lol!! :-)

    I stand corrected! :-P

      As the moderator of all Wikipedia, I can confirm this.

      • http://www.geeksonhugs.com/ W. Anthony Tanas


  • JG

    Here's another code name question...

    The full timeline goes like this:Android milestone builds (with Astro Boy and Bender floating around in here somewhere)Android 1.0 (No codename)Android 1.1 - Petit FourAndroid 1.5 - CupcakeAndroid 1.6 - DonutAndroid 2.0 - ÉclairAndroid 2.1 - ÉclairAndroid 2.2 - FroyoAndroid 2.3 - GingerbreadAndroid 3.0 - HoneycombAndroid 4.0 - Ice Cream SandwichAndroid 4.1 - Jelly Bean

    So, um... Why did 2.0 and 2.1 share the Éclair designation? Other 0.1 increments were assigned their own name... So, shouldn't my Nexus 7 be running 4.1, Key Lime, and my Droid X be stuck on 2.3, Honeycomb?

    • blunden

      The most likely answer is that 2.0 (and 2.0.1) were released exclusively on the Motorola Droid/Milestone. From what I remember they never really felt finished so I assume they weren't. Google then released the full Eclair with the release of the Nexus One and also pushed it to AOSP.

      • Quake

        Maybe. Or it was just an update. Who knows?

    • http://www.androidpolice.com/author/ron-amadeo/ Ron Amadeo

      Yes. That was weird.True, but weird. 2.1 came out very quickly after 2.0, and didn't have any new user-facing features, so it kept the codename.

      From http://source.android.com/source/overview.html :"The Eclair branch was also used for 2.0 and 2.0.1; however, both of those releases were quickly obsoleted by the version 2.1 Eclair release. As Android 2.1 includes key bug fixes and improvements not present in 2.0/2.0.1, only Android 2.1 should be used for new devices. As there is no compatibility program for 2.0 or 2.0.1, the officially compatible Eclair-based release is Android 2.1"

  • Marko

    I swear that when I got my G1, it had version 0.9 on it. I was excited when it graduated to 1.0!

    Then how do I believe this?

  • CeluGeek

    Sillier than the "Astro" and "Bender" names, is the fact that there are two versions of Android named Éclair. I guess no one had figured out a F-dessert after 2.0 Éclair was released so they had to reuse Éclair.

    • Edward Rubio

      I think that it was such a small update that they werent touting it as an UPDATE. It was basically just bug fixes.

      • Simon Belmont

        This. Android 2.0 was only released on the OG Droid.

        As you said Android 2.1 was just some bug fixes. Cheers.

    • Lawrence D’Oliveiro

      And three versions of Honeycomb (3.0, 3.1, 3.2). And counting API levels, there were two for Gingerbread and two for Ice Cream Sandwich as well.

  • Simon Belmont

    Heh. It would be a cool homage for them to reuse "Petit Four" when they get to 'P' in the alphabet.

    I am not saying it will happen, but I would think it'd be a cool look back in Android's history. My two cents.

    • Quake

      Wouldnt that be confusing for them?

    What happened to 1.2, 1.3 and 1.4?
