INTERODUCTION

INTRODOCTION

1. Android is a software cluster for mobile devices that includes an operating system OS, key application and middleware.

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

3. Android doesn’t have a essential X windows system nor does it support the full set of standard GNU libraries, which marks it difficult to port existing Linux application or libraries to Android.Applications

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

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, form the boot loader all the way up to the application.

PLATFORMOPERATING 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 coda's, the SQL database and a web Brower angine(web kit).

PLATFORMNETWORK CONNECTIVITY

It support 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 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.

PLATFORMFUTURE 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.

SOFTWARE DEVELOPMENTDEVELOPMENT REQUIREMENTS• JAVA• Android SDK• Eclipse IDE (or) Mono Develop (Xamarin)
