3. Android is a mobile operating system developed by Google. It is based
on a modified version of the Linux kernel and other open
source software, and is designed primarily for touchscreen mobile
devices such as smartphones and tablets. Initially developed by
Android Inc., which Google bought in 2005, Android was unveiled in
2007, with the first commercial Android device launched in September
2008. The current stable version is Android 9 "Pie", released in August
2018.
What is Android Operating System?

4. Android Inc. was founded in Palo Alto, California, in October 2003 by
Andy Rubin, Rich Miner, Nick Sears, and Chris White. Rubin described
the Android project as "tremendous potential in developing smarter
mobile devices that are more aware of its owner's location and
preferences". The early intentions of the company were to develop an
advanced operating system for digital cameras, and this was the basis
of its pitch to investors in April 2004. The company then decided that
the market for cameras was not large enough for its goals, and by five
months later it had diverted its efforts and was pitching Android as a
handset operating system that would rival Symbian and
Microsoft Windows Mobile.
History of Android Operating System

5. • Interface: Android's default user interface is mainly based on direct
manipulation, using touch inputs that loosely correspond to real-world actions,
like swiping, tapping, pinching, and reverse pinching to manipulate on-screen
objects, along with a virtual keyboard.
• Applications: Applications ("apps"), which extend the functionality of devices, are
written using the Android software development kit (SDK)[76] and, often,
the Java programming language.[77] Java may be combined
with C/C++,[78] together with a choice of non-default runtimes that allow better
C++ support.
• Memory management: Since Android devices are usually battery-powered,
Android is designed to manage processes to keep power consumption at a
minimum. When an application is not in use the system suspends its operation so
that, while available for immediate use rather than closed, it does not use battery
power or CPU resources.
