Android is a mobile operating system developed by Google, based on the Linux kernel and designed for touchscreen devices. It uses touch gestures like swiping and tapping to interact with onscreen objects. Variants of Android are used in cars, watches, notebooks, cameras and other electronics. Android has the largest market share of any operating system, dominating the smartphone and tablet markets. It was developed by an open source consortium called the Open Handset Alliance, and uses open standards that are publicly available.
