Revision as of 12:31, 23 September 2013

Global Android version distribution since December 2009. As of September 2013, Android 4.1/4.2 Jelly Bean is the most widely-used Android version, operating on around 45% of Android devices worldwide.

The version history of the Android mobile operating system began with the release of the Android beta in November 2007. The first commercial version, Android 1.0, was released in September 2008. Android is under ongoing development by Google and the Open Handset Alliance (OHA), and has seen a number of updates to its base operating system since its initial release.

Since April 2009, Android versions have been developed under a codename and released according to alphabetical order: Cupcake (1.5), Donut (1.6), Eclair (2.0–2.1), Froyo (2.2–2.2.3), Gingerbread (2.3–2.3.7), Honeycomb (3.0–3.2.6), Ice Cream Sandwich (4.0–4.0.4), Jelly Bean (4.1–4.3), and KitKat (4.4). On 3 September 2013 Google announced that 1 billion activated devices now use the Android OS worldwide.[1] The most recent major Android update was Jelly Bean 4.3, which was released on commercial devices on 24 July 2013 via an OTA update.[2][3]

On 3 September 2013, Google announced Jelly Bean's successor as Android 4.4, KitKat, with a release date yet to be announced.[4][5]

Pre-commercial release versions (2007–2008)

Android alpha

There were at least two internal releases inside Google and the OHA before the Android beta was released in November 2007. In a temporary naming scheme, names of fictional robots were chosen, and various releases were code-named "Astro Boy", "Bender" and "R2-D2".[6][7] Dan Morrill created some of the first mascot logos, but the current green Android logo was designed by Irina Blok.[8] The project manager, Ryan Gibson, conceived of the confections naming scheme that has been used for the majority of the public releases, starting with Android 1.5 Cupcake in April 2009.

Android beta

The Android beta was released on 5 November 2007,[9][10] while the software development kit (SDK) was released on 12 November 2007.[11] The 5 November date is popularly celebrated as Android's "birthday".[12] Public beta versions of the SDK were released in the following order:

  • 16 November 2007: m3-rc22a[13]
  • 14 December 2007: m3-rc37a[14]
  • 13 February 2008: m5-rc14[15]
  • 3 March 2008: m5-rc15[16]
  • 18 August 2008: 0.9[17]
  • 23 September 2008: 1.0-r1[18]
