Global Android version distribution since December 2009. As of September 2016, Android Lollipop (5.0 – 5.1) is the single most widely used Android version, operating on 35.0% of all Android devices accessing Google Play. The second is Android KitKat (4.4), with a share of 27.7%.

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

Versions 1.0 and 1.1 were not released under specific code names, but since April 2009's Android 1.5 "Cupcake", Android versions have had confectionery-themed code names. Each is in alphabetical order, with the most recent being Android 7.0 "Nougat", released in August 2016.[1]

Pre-commercial release versions

The development of Android started in 2003 by Android, Inc., which was purchased by Google in 2005.[2]

Alpha

There were at least two internal releases of the software inside Google and the OHA before the beta version was released.[3][4]

Dan Morrill created some of the first mascot logos, but the current green Android logo was designed by Irina Blok.[5] The project manager, Ryan Gibson, conceived the confectionery-themed naming scheme that has been used for the majority of the public releases, starting with Android 1.5 "Cupcake".

Beta

The beta was released on November 5, 2007,[6][7] while the software development kit (SDK) was released on November 12, 2007.[8] The November 5 date is popularly celebrated as Android's "birthday".[9] Public beta versions of the SDK were released in the following order:[10]

  • November 12, 2007: m3-rc20a (milestone 3, release code 20a)[11]
  • November 16, 2007: m3-rc22a (milestone 3, release code 22a)[12]
  • December 14, 2007: m3-rc37a (milestone 3, release code 37a)[13]

Android 4.4 KitKat (API level 19)

Android 4.4 KitKat (API level 19)
Google announced Android 4.4 KitKat on September 3, 2013. Although initially under the "Key Lime Pie" ("KLP") codename, the name was changed because "very few people actually know the taste of a key lime pie."[128] Some technology bloggers also expected the "Key Lime Pie" release to be Android 5.[129] KitKat debuted on Google's Nexus 5 on October 31, 2013, and was optimized to run on a greater range of devices than earlier Android versions, having 512 MB of RAM as a recommended minimum; those improvements were known as "Project Svelte" internally at Google.[130] The required minimum amount of RAM available to Android is 340 MB, and all devices with less than 512 MB of RAM must report themselves as "low RAM" devices.[131]

Hardware requirements

See also: Android Hardware

The main hardware platform for Android is the ARM architecture (ARMv7 and ARMv8-A architectures), with x86[c] and MIPS[d] architectures also officially supported in later versions of Android. Since Android 5.0 "Lollipop", 64-bit variants of all platforms are supported in addition to the 32-bit variants.[213] Unofficial Android-x86 project used to provide support for the x86 and MIPS architectures ahead of the official support.[214][215] Since 2012, Android devices with Intel processors began to appear, including phones[216] and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64.[citation needed]

Requirements for the minimum amount of RAM for devices running Android 5.1 range from 512 MB of RAM for normal-density screens, to about 1.8 GB for high-density screens.[217] The recommendation for Android 4.4 is to have at least 512 MB of RAM,[218] while for "low RAM" devices 340 MB is the required minimum amount that does not include memory dedicated to various hardware components such as the baseband processor.[131] Android 4.4 requires a 32-bit ARMv7, MIPS or x86 architecture processor (latter two through unofficial ports),[214][219] together with an OpenGL ES 2.0 compatible graphics processing unit (GPU).[220] Android supports OpenGL ES 1.1, 2.0, 3.0, 3.1 and as of latest major version 3.1 and Vulkan. Some applications may explicitly require a certain version of the OpenGL ES, and suitable GPU hardware is required to run such applications.[220]

Android used to require an autofocus camera, which was relaxed to a fixed-focus camera[221] if present at all, since the camera was dropped as a requirement entirely (except for smartphones) when Android started to be used on set-top boxes.

Notes

  1. ^ The 2.3.6 update had the side-effect of impairing the Wi-Fi hotspot functionality of many Canadian Nexus S phones. Google acknowledged this problem and fixed it in late September.[62][63]
  2. ^ For Canadian consumers, 4.0.2 reportedly created a bug on the Galaxy Nexus that crashed the application market when users attempted to view details of any Android application. It also inadvertently reduced the NFC capabilities of the Nexus phone.[88][89]
  3. ^ Lowest supported x86 generation is the P6 microarchitecture, also called i686.[211]
  4. ^ Supported is revision 1 of MIPS32[212] and revision 6 for 64-bit MIPS64[211]
