Android is a mobile phone operating-system (OS) currently produced by Google, based on the Linux kernel and made for touchscreen mobile devices such as smartphones and tablets primarily. Android's user interface is principally predicated on direct manipulation, using touch gestures that match real-world actions loosely, such as swiping, pinching and tapping, to control on-screen objects, plus a virtual keyboard for text input. Furthermore to touchscreen devices, Google has further developed Google android TV for televisions, Android Auto for autos, and Android Have on for designer watches, each with a particular user interface. Variants of Android are being used on notebooks also, game consoles, digital camera models, and other electronics.
Android has the major installed base of all operating systems of any kind. Android has been the very best selling OS on tablets since 2013, and on smartphones it really is dominant by any metric. An April-May 2013 study of mobile application programmers discovered that 71% of designers create applications for Android os, and a 2015 study discovered that 40% of full-period professional developers see Android os as their priority concentrate on platform, which is related to Apple's iOS on 37% with both platforms significantly above others. At Google I/O 2014, the ongoing enterprise revealed that there have been over one billion energetic monthly Android users, in June 2013 up from 538 million.
Android's origin code is produced by Google under open up source licenses, although most Android devices finally ship with a combo of open source and proprietary software, including proprietary software necessary for accessing Google services. Google android is favored by technology companies that want a ready-made, low-expense and customizable operating-system for high-tech devices. Its open nature has encouraged a huge community of developers and enthusiasts to utilize the open-source code as a foundation for community-driven projects, which add new features for advanced users or bring Android to devices at first shipped with other os's. As well, as Android does not have any centralised update system virtually all Android devices neglect to receive security updates: study in 2015 figured almost 90% of Google android phones used had known but unpatched security vulnerabilities because of lack of improvements and support. The achievements of Android has managed to get a goal for patent litigation within the so-known as "smartphone wars" between technology companies.
Android comes with an active community of creators and enthusiasts who utilize the Android Open Source Job (AOSP) source code to build up and distribute their personal modified editions of the operating-system. These community-developed releases sometimes bring new improvements and features to gadgets faster than through the state manufacturer/carrier channels, with a comparable quality level; provide ongoing support for older products that no more receive official updates; or bring Android to units which were officially released running different operating systems, including the HP TouchPad. Community releases often arrive pre-rooted and have modifications not supplied by the original vendor, like the capability to overclock or over/undervolt the device's processor. CyanogenMod may be the hottest community firmware, and functions as a basis for countless others. There are also attempts with varying levels of success to port Android os to iPhones, the iDroid Project notably.
