1 Introduction
What is Android? Android is a software platform and operating system for mobile devices,based on the Linux kernel, developed by Google and later the Open Handset Alliance. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries. Applications written in C and other languages can be compiled to ARM native code and run, but this development path is not officially supported by Google. The unveiling of the Android platformon 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 48 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache license, a free-software and open source license. What is The Open Handset Alliance? Open Handset Alliance, is a consortium of severalcompanies which include Google, HTC, Intel, Motorola, Qualcomm, T-Mobile, Sprint Nextel and NVIDIA, ... These companies which aim to develop technologies that will significantly lower the cost of developing and distributing mobile devices and services. The Android platform is the first step in this direction -- a fully integrated mobile "software stack" that consists of an operating system, middleware,user-friendly interface and applications. License Android is under version 2 of the Apache Software License (ASL). The Apache license allows manufacturers and mobile operators to innovate using the platform without the requirement to contribute those innovations back to the open source community.

2.1 Hardware
First and foremost, Android is a software stackfor mobile devices. This means that high on the list of priorities is the preservation of battery power and the efficient management of limited memory resources. There are five distinct layers to the Android system stack:
•

The Acorn RISC Machine (ARM) Linux core forms the solid base upon which all the other layers stand. Linux is a proven technology that is highly reliable, and the ARMprocessor family is known for high performance on very low power requirements. The libraries provide the reusable and sharable low-level code for basic functions such as codecs — software for coding and decoding digital sound and video — functions for the presentation of rich graphics on a small displays, secure shell support for encrypted TCP/IP traffic into the cloud, as well as component support forWeb browsing (WebKit), SQL database functionality (SQLite), and standard C library functionality you would expect in a Linux system. The Dalvik run-time byte-code interpreter, which strongly resembles the Java™ language byte-code interpreter, adds a few distinct features that uniquely define the security and power-preserving model of Android. Every application currently running, for example, hasits own user ID and its own copy of the interpreter running to strictly separate processes for security and reliability. The Android application framework enables you to use and replace components as you see fit. These high-level Java classes are tightly integrated components that define the Android API. The Android core applications include the WebKit browser, Google calendar, Gmail, Mapsapplication, SMS messenger, and a standard e-mail client, among others. Android applications are written in the Java programming language, and you can download many more from the Android market on the fly.
