ANDROID

History:

 Android is a Linux kernel based operating system  with an interactive interface, designed primarily for touchscreen mobile devices, with variants for televisions,cars and watches. The operating system uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard.Despite being primarily designed for touchscreen input, it also has been used in television,games,consoles.digital cameras and other electronics.

Android, Inc. was founded in Palo Alto.California, in October 2003 by Andy Rubin , Rich Miner (co-founder of Wildfire Communications, Inc.),Nick Sears, and Chris White (headed design and interface development at WebTV), Rubin wanted "smarter mobile devices that are more aware of its owner's location and preferences".The early intentions of these people were to design an OS for cameras but on frealising that it has a little scope in market, they shifted on to smartphone Operating System.

 But midway,Rubin ran out of money. Steve Perlman, a close friend of Rubin, brought him $10,000 in cash in an envelope and refused a stake in the company. Then Google acquired Android Inc. on August 17, 2005; key employees of Android Inc., including Rubin, Miner, and White, stayed at the company after the acquisition. Not much was known about Android Inc. at the time, but many assumed that Google was planning to enter the mobile phone market with this move and that was pretty true.

Android Logo:

The green Android logo was designed  to create a universally identifiable icon with the specific inclusion of a robot in the final design. After numerous design developments based on science-fiction and space movies, the team eventually sought inspiration from the human symbol on restroom doors and modified the figure into a robot shape.
