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

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

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. For information about reporting security issues and the update process

CONTi….Android is a multi-process system, in which eachapplication (and parts of the system) runs in its ownprocess. Most security between applications and thesystem is enforced at the process level through standardLinux facilities, such as user and group IDs that areassigned 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.

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 modifedyou 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 Android App Market
