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.
