INTRODUCTION

INTRODUCTION Android is a software cluster for mobile devices that includes an

operating system OS, key applications and middleware.

About the design, Kernel of Android is based on Linux kernel further furnished by Google.

Android doesn’t have a essential X Windows System nor does it support the full set of standard GNU libraries, which makes it difficult to port existing Linux applications or libraries to Android.

Origin OF ANDROID

.

ORIGIN OF ANDROID Android was founded in Palo Alto, California in October 2003 by

Andy Rubin, Rich Miner, Nick Sears and Chris White who work at

“Google” to develop.

“…smarter mobile devices that are more aware of its owner’s

location and preferences.”

Andy Rubin

ORIGIN OF ANDROID Android was bought by “Google” in 2005.

On the 5th of the November 2007 the Open Handset Alliance, a

consortium of several companies was unveiled with the goal to

develop open standards for mobile services.

PLATFORM

PLATFORM

HARDWARE

Android is not a single piece of hardware; it’s a complete, end-to-

end software platform that can be adapted to work on any

number of hardware configurations.

Everything is there, from the boot loader all the way up to the

applications

PLATFORM

PLATFORM OPERATING SYSTEM

Android uses Linux for its device drivers, memory management,

process management and networking.

The next level contains Android native libraries. They are all

written in C/C++ internally, but calling through Java interfaces,

In this layer, Surface Manager, 2D and 3D graphics, Media

Codecs, the SQL database (SQLite) and a web browser engine

(WebKit).

PLATFORM NETWORK CONNECTIVITY

It supports wireless communications using :

GSM mobile-phone technology

3G technology

802.11 Wi-Fi networks

PLATFORMSECURITY

Android is a multi-process system, in which each application (and

parts of the system) runs in its own process.

Most security between applications and the system is enforced at

the process level through standard Linux facilities, such as user

and group IDs that are assigned to applications.

PLATFORM FUTURE POSSIBILITIES

The OHA is committed to make their vision a reality: to deploy the

Android platform for every mobile operator, handset

manufacturers and developers to build innovative devices

Intel doesn’t want to lose ownership of the netbook market, so

they need to prepare for anything, including Android

More Android devices are coming and some will push the

envelope even further
