The history of the Android mobile operating system started with the beta public beta release on November 5, 2007. The first commercial version, Android 1.0, was released in September 2008. Android continues to be developed by Google and the Open Handset Alliance, and has seen a number of updates to its basic operating system early release.
Versions 1.0 and 1.1 are not released with a specific code name. Android code names are confectionery and have been alphabetically alphabetical since 2009's AndroidÃ, Cupcake, with the latest major version is AndroidÃ, 8.1 Oreo, released in December 2017.
The exclusive Android KitKat version for Android Wear devices was released on June 25, 2014, with API level 20, and has since been renamed to Wear OS.

Pre-commercial release version
Android development started in 2003 by Android, Inc., purchased by Google in 2005.
Alpha
There are at least two internal releases of software inside Google and OHA before the beta version is released.
To avoid confusion, the code names "Astro Boy" and "Bender" are only known to be marked internally at some initial milestones pre-1.0, and thus never used as the actual code names of the 1.0 and 1.1 releases of the OS, as many people wrongly calling and repeating on the web. And Morrill created some of the first mascot logos, but the Android logo is currently designed by Irina Block. The project manager, Ryan Gibson, devised a candy-themed naming scheme that has been used for most public releases, starting with Android 1.5 Cupcake.
Beta
The beta was released on November 5, 2007, while the software development tool (SDK) was released on November 12, 2007. November 5th is popularly celebrated as the "birthday" of Android. The public beta version of SDK is released in the following order:
- November 12, 2007: m3-rc20a (milestone 3, release code 20a)
- November 16, 2007: m3-rc22a (milestone 3, release code 22a)
- December 14, 2007: m3-rc37a (milestone 3, release code 37a)
- February 13, 2008: m5-rc14 (milestone 5, code release 14)
- March 3, 2008: m5-rc15 (milestone 5, code release 15)
- August 18, 2008: 0.9 Beta
- September 23, 2008: 1.0-r1

Version history by API level
The following table shows the release dates and key features of all the latest Android operating system updates, listed chronologically based on their official application programming API (API) interface level.
Hardware requirements
The main hardware platform for Android is the ARM architecture (ARMv7 and ARMv8-A architecture, formerly also ARMv5), with the x86 architecture and MIPS also officially supported in newer Android versions, but MIPS support has since been deprecated.
The unofficial Android-x86 project is used to provide support for the x86 and MIPS architectures in front of official support. In 2012, Android devices with Intel processors are starting to appear, including phones and tablets. While getting support for the 64-bit platform, Android was first built to run on 64-bit x86 and later on ARM64. Because Android 5.0 Lollipop, 64-bit variants of all platforms are supported in addition to the 32-bit variant.
The requirement for minimum amount of RAM for devices running Android 7.1 depends on screen size and density and CPU type, ranging from 816 Ã, MB-1.8 Ã, GB to 64-bit and 512 Ã, MB-1.3 Ã, GB for the 32-bit meaning in practice 1 Ã, GB for the most common view type (while the minimum for Android Jam is 416 Ã, MB). The recommendation for Android 4.4 is to have at least 512 MB of RAM, while for "low RAM" devices, 340 MB is the minimum required number that does not include dedicated memory for various hardware components such as baseband processors. Android 4.4 requires an ARMv7, MIPS, or x86 32-bit architecture processor (most recently through unauthorized ports), along with a compatible OpenGL ES 2.0 graphics processing unit (GPU). Android supports OpenGL ES 1.1, 2.0, 3.0, 3.2 and since Android 7.0 Vulkan (and version 1.1 is available for some devices). Some applications explicitly require a specific version of OpenGL ES, and the appropriate GPU hardware is required to run the application.
Android is used to require an autofocus camera, which is casual to the fixed focus camera
