• 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.”

• 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.

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

PLATFORM

NETWORK CONNECTIVITY

It support wireless communications using.

• GSM mobile-phone technology

• 3G technology

• 802.11 Wi-Fi networks

PLATFORM

SECURITY

• 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.

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 netbookmarket, so they need to prepare for anything, including Android.

• More Android devices are coming and some will push the envelope even further.
