ANDROID, THE GREEN ROBOT.

Android is a mobile device operating system developed by Google, designed primarily for embedded systems such as smartphones and tablets, with specialized user interfaces for televisions (Android TV), cars (Android Auto), wristwatches (Wear OS), glasses (Google Glass), and others.

It is based on the Linux kernel and is properly considered an embedded Linux distribution and not a unix-like system or a GNU / Linux distribution.
In April 2017 it is the most popular operating system for mobile devices in the world, with a market share of 62.94%. On August 17th, 2005, Google LLC acquired the company, in view of the fact that the Mountain View company wanted to enter the mobile phone market. It is in these years that Rubin’s team begins to develop an operating system for mobile devices based on the Linux kernel. The official presentation of the “green robot” took place on November 5, 2007 by the newly formed OHA (Open Handset Alliance), a consortium of companies in the Hi Tech sector that includes Google, smartphone manufacturers, such as HTC and Samsung, mobile phone operators, such as Sprint Nextel and T-Mobile, and microprocessor manufacturers, such as Qualcomm and Texas Instruments Incorporated.
