What is Android?
Android is a Linux-based operating system for mobile devices such as smartphones and tablet computers, developed by Google in conjunction with the Open Handset Alliance. Android is the world's most popular mobile platform. With Android you can use all the Google apps you know and love, plus there are more than 600,000 apps and games available on Google Play to keep you entertained, alongside millions of songs and books, and thousands of movies.
What is Android?
Android devices are already smart, and will only get smarter, with new features you won't find on any other platform, letting you focus on what's important and putting you in control of your mobile experience.
Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Developers write primarily in a customized version of Java, and apps can be downloaded from online stores such as Google Play (formerly Android Market), the app store run by Google, or third-party sites.

Millions of people already use Android because it makes your mobile device so much more powerful and useful.

Screencapture Android supports capturing
a screenshot by pressing the power and volume-down buttons at the same time.[61] Prior to Android 4.0, the only methods of capturing a screenshot were through manufacturer and third-party customizations or otherwise by using a PC connection (DDMS developer's tool). These alternative methods are still available with the latest Android.
DESIGN
DESIGN
Android consists of a kernel based on the Linux kernel 2.6 and Linux Kernel 3.x (Android 4.0 onwards), with middleware, libraries and APIs written in C and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik dex-code (Dalvik Executable), which is usually translated from Java bytecode.[34]
DESIGN
The main hardware platform for Android is the ARM architecture. There is support for x86 from the Android x86 project,[6] and Google TV uses a special x86 version of Android.
APPLICATIONS ARE USUALLY DEVELOPED IN THE JAVA LANGUAGE USING THE
ANDROID SOFTWARE DEVELOPMENT KIT, BUT OTHER DEVELOPMENT TOOLS ARE
AVAILABLE, INCLUDING A NATIVE DEVELOPMENT KIT FOR APPLICATIONS OR EXTENSIONS IN C OR C++, GOOGLE
APP INVENTOR, A VISUAL ENVIRONMENT FOR NOVICE PROGRAMMERS AND
VARIOUS CROSS PLATFORM MOBILE WEB APPLICATIONS FRAMEWORKS.
