2. Android is a mobile operating system developed by Google, based on the Linux
kernel and designed primarily for touch screen mobile devices such as smart
phones and tablets. Android's user interface is mainly based on direct manipulation,
using touch gestures that loosely correspond to real-world actions, such as swiping,
tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for
text input. In addition to touch screen devices, Google has further developed Android
TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each
with a specialized user interface. Variants of Android are also used on notebooks, game
consoles, digital cameras, and other electronics.
