Global Android version distribution since December 2009. As of March 2014, Android 4.x Jelly Bean is the most widely used Android version, operating on around 62% 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 confectionery-themed code name 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 KitKat 4.4, which was released to commercial devices on 22 November 2013, via an OTA update.[2][3]

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. For the milestones in internal releases, names of fictional robots were chosen, with various releases code-named "Astro Boy", "Bender" and "R2-D2".[4][5][6] Dan Morrill created some of the first mascot logos, but the current green Android logo was designed by Irina Blok.[7] 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.

Android beta

The Android beta was released on 5 November 2007,[8][9] while the software development kit (SDK) was released on 12 November 2007.[10] The 5 November date is popularly celebrated as Android's "birthday".[11] Public beta versions of the SDK were released in the following order:

  • 16 November 2007: m3-rc22a[12]
  • 14 December 2007: m3-rc37a[13]
  • 13 February 2008: m5-rc14[14]
  • 3 March 2008: m5-rc15[15]
  • 18 August 2008: 0.9[16]
  • 23 September 2008: 1.0-r1[17]

Hardware requirements

The main hardware platform for Android is the 32-bit ARMv7 architecture. The Android-x86 project provides support for the x86 architecture,[18] and Google TV uses a special x86 version of Android. In 2012, Intel processors began to appear on more mainstream Android platforms, such as phones.[19] In 2013, Freescale announced support for Android on its i.MX processor, specifically the i.MX5X and i.MX6X series.[20]

Minimum hardware requirements have been upgraded in steps over time, with the new Android versions releases. Original minimums were 32 MB of RAM, 32 MB of Flash memory, and a 200 MHz ARM architecture (ARMv5) processor.[21][22] As of October 2011 and version 4.0, a graphics processing unit (GPU) that supports OpenGL ES 2.0 hardware acceleration is mandatory,[23] regardless of whether applications directly use the OpenGL ES or not.

As of November 2013 and Android version 4.4, an ARMv7 processor is required, while recommended minimum amount of RAM is 512 MB.[24] The required minimum amount of RAM available to Android 4.4 is 340 MB, and all devices with less than 512 MB of RAM must report themselves as "low RAM" devices.[25] MIPS and x86 architectures are also supported through unofficial ports.[18][26] OpenGL ES 2.0 hardware acceleration is still mandatory, while OpenGL ES 3.0 is supported.[23]
