The document discusses the history and features of the Android operating system. It describes how Android was founded in 2003 and provides an overview of its architecture, versions, requirements, features including its application framework and use of the Linux kernel. The document also covers Android's advantages like open source development and customization, as well as its security features and multi-layered security design.

3. INTRODUCTION
 Android is an open source operating system,
maintained by Google specifically for use on mobile
devices (cell phones and tablets)
 Linux based (3.28 kernel)
 Most apps development is done in Java
 Supports Bluetooth, Wi-Fi, and 3G and 4G networking
and other API

4. HISTORY OF ANDROID
 Android Inc.founded in Palo Alto,california ,united
states in October 2003 by Andy Rubin[co-founder of
danger ],rich miner[co-founder of wildfire
communication Inc.],nick sears[once VP at T-mobile],
and Chris white[headed design and interface
development at web TV] to develop.

10. ANDROID INCRESED DAY BY
DAY
 Android apps can be developed on any platform (Windows XP and
Vista, Linux, and Mac OS X) .
 Android can support the same hardware as the iPhone: touchscreen,
accelerometer, GPS, WiFi, SMS & still camera; plus features that
other os do not support gesture agps AMOLED root coustom ROM.
 Android is a free OS so an Android-enabled smartphone should be
cheaper than a normal smartphone. All the major manufacturers are
looking at using it.
 Anyone can develop and launch an Android app whereas Apple has
strict control of their App Store.
 Android has some fresh ideas like Google Maps “street view” and
customisable home page and many more

14. Security of
android
 Android is a modern mobile platform that was designed to be truly
open. Android applications make use of advanced hardware and
software, as well as local and served data, exposed through the
platform to bring innovation and value to consumers. To protect
that value, the platform must offer an application environment that
ensures the security of users, data, applications, the device, and the
network.
 Securing an open platform requires a robust security architecture
and rigorous security programs. Android was designed with multi-
layered security that provides the flexibility required for an open
platform, while providing protection for all users of the platform.

15. CONTi….
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.
Android was designed with device users in mind. Users are provided visibility into how
applications work, and control over those applications. This design includes the
expectation that attackers would attempt to perform common attacks, such as social
engineering attacks to convince device users to install malware, and attacks on third-
party applications on Android. Android was designed to both reduce the probability of
these attacks and greatly limit the impact of the attack in the event it was successful.
This documentation outlines the goals of the Android security program, describes the
fundamentals of the Android security architecture, and answers the most pertinent
questions for system architects and security analysts. This document focuses on the
security features of Android's core platform and does not discuss security issues that
are unique to specific applications, such as those related to the browser or SMS
application. Recommended best practices for building Android devices, deploying
Android devices, or developing applications for Android are not the goal of this
document and are provided elsewhere.

17. CONCLUSION
 Android is a better option for operting system now a
days it offering a large veriaty of features and great
support it also provide a better user interface and a
great application market and improving it is better
cheaper for a smart phone
 Android allow the feature of mullitasking and help to
modifed
you must know that you can easy access to thousands of
applications via theGoogle Android App Market , When you
love to install the applications or the games through Google
