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.
The most recent major Android update is Android 5.0 "Lollipop", which was released on November 3, 2014. Since April 2009, Android versions have been developed under a confectionery-themed code name and released in alphabetical order, beginning with Android 1.5 "Cupcake"; the earlier versions 1.0 and 1.1 were not released under specific code names:
- 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 (4.1–4.3.1)
- KitKat (4.4–4.4.4, 4.4W–4.4W.2)
- Lollipop (5.0–5.1.1)
- [[Android M (Version 6.0)
On September 3, 2013, Google announced that one billion activated Android devices were in use worldwide.[2] In January 2015, Android devices accounted for approximately 62% of the US smartphone and tablet market, 82.7% of the Chinese market, and 73.3% of the European market.[citation needed]
Pre-commercial release versions
The development of Android started in 2003 by Android, Inc., which was purchased by Google in 2005.[3]
Alpha
There were at least two internal releases of the software inside Google and the OHA before the beta version 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 the confectionary-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,[8][9] while the software development kit (SDK) was released on November 12, 2007.[10] The November 5 date is popularly celebrated as Android's "birthday".[11] Public beta versions of the SDK were released in the following order:[12]
- November 12, 2007: m3-rc20a (milestone 3, release code 20a)[13]
- November 16, 2007: m3-rc22a (milestone 3, release code 22a)[14]
- December 14, 2007: m3-rc37a (milestone 3, release code 37a)[15]
- February 13, 2008: m5-rc14 (milestone 5, release code 14)[16]
- March 3, 2008: m5-rc15 (milestone 5, release code 15)[12]
- August 18, 2008: 0.9[17][18]
- September 23, 2008: 1.0-r1[19][20]

---|---|---|---|
Google announced Android 4.1 (Jelly Bean) at the Google I/O conference on June 27, 2012. Based on Linux kernel 3.0.31, Jelly Bean was an incremental update with the primary aim of improving the functionality and performance of the user interface. The performance improvement involved "Project Butter", which uses touch anticipation, triple buffering, extended vsync timing and a fixed frame rate of 60 fps to create a fluid and "buttery-smooth" UI.[96] Android 4.1 Jelly Bean was released to the Android Open Source Project on July 9, 2012,[97] and the Nexus 7 tablet, the first device to run Jelly Bean, was released on July 13, 2012. | |||

---|---|---|---|
Google was expected to announce Jelly Bean 4.2 at an event in New York City on October 29, 2012, but the event was cancelled due to Hurricane Sandy.[105] Instead of rescheduling the live event, Google announced the new version with a press release, under the slogan "A new flavor of Jelly Bean". Jelly Bean 4.2 was based on Linux kernel 3.4.0, and debuted on Google's Nexus 4 and Nexus 10, which were released on November 13, 2012.[106][107] | |||

Google released Jelly Bean 4.3 under the slogan "An even sweeter Jelly Bean" on July 24, 2013, during an event in San Francisco called "Breakfast with Sundar Pichai". Most Nexus devices received the update within a week, although the second-generation Nexus 7 tablet was the first device to officially ship with it.[117] A minor bugfix update was released on August 22, 2013.[118] | |||

Android 4.4–4.4.4 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."[129] Some technology bloggers also expected the "Key Lime Pie" release to be Android 5.[130] KitKat debuted on Google's Nexus 5 on October 31, 2013, and was optimised 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.[131] 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.[132] | |||

Android 5.0–5.0.2 Lollipop (API level 21) | |||
---|---|---|---|
Android 5.0 "Lollipop" was unveiled under the codename "Android L" on June 25, 2014, during Google I/O. It became available as official over-the-air (OTA) updates on November 12, 2014, for select devices that run distributions of Android serviced by Google, including Nexus and Google Play edition devices. Its source code was made available on November 3, 2014.[160][161]
Lollipop features a redesigned user interface built around a responsive design language referred to as "material design". Other changes include improvements to the notifications, which can be accessed from the lockscreen and displayed within applications as top-of-the-screen banners. Furthermore, Google made internal changes to the platform, with the Android Runtime (ART) officially replacing Dalvik for improved application performance, and with changes intended to improve and optimize battery usage, known internally as Project Volta.[162][163][164][165] | |||

Another new version of Android M has supposedly been started development on as of 19th May 2015. [185]
Hardware requirements
The main hardware platform for Android is the ARM architecture, with x86 and MIPS architectures also officially supported. Both 64-bit and 32-bit variants of all three architectures are supported since the release of Android 5.0;[186] unofficial Android-x86 project had provided support for the x86 and MIPS architectures ahead of the official support.[187][188] Since 2012, Android devices with Intel processors began to appear, including phones[189] and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64.
Minimum hardware requirements have been upgraded in steps over time, with the new Android version releases. Original minimums were 32 MB of RAM (but less than 128 MB was not recommended,[190] with first phone HTC Dream ("flagship") phone using 192 MB), 32 MB of Flash memory, and a 200 MHz ARM architecture (ARMv5) processor.[191][192] As of November 2013[update] and Android version 4.4, builds for ARM-based devices require an ARMv7 processor (Android 5.0 also supports ARMv8-A), while recommended minimum amount of RAM is 512 MB.[131] The required minimum amount of RAM available to Android 4.4 is 340 MB (this amount does not include memory dedicated to various hardware components such as the baseband processor), and all devices with less than 512 MB of RAM must report themselves as "low RAM" devices.[132]
With the release of Android 4.0 in October 2011, a graphics processing unit (GPU) supporting OpenGL ES 2.0 (and ES 1.0) hardware acceleration became mandatory,[193] regardless of whether installed applications directly use the OpenGL ES or not. Later, Android 4.3 added support for OpenGL ES 3.0; if used, support for both older versions (ES 2.0 and 1.0) is still mandatory.[193]
In addition to running directly on x86-based hardware, Android can also be run on x86 architecture by using official Android emulator as part of the Android SDK, or by using third-party emulators such as BlueStacks or Andy.[194][195]
