Android It is and open source i.
It is the first open source platform of mobile development. It contains the complete set of components like operating system, middleware and all the components up the hierarchy. Android was built from bottom to the layer where developers can develop their own application.
Android is so created that any user can fully utilize his handset for running the application built on android platform.
Linux Kernel We all are aware of the fact that android is built on open Linux kernel 2. The android architecture contains following components Linux kernel, native libraries, surface manager, SQLite, web kit. It provides the freedom for the developers to develop applications which are so designed that unifies them it breaks all the barriers of development of applications.
Her Linux kernel is used as an abstract layer as a hardware. And the mobile manufactures if want to implement his technology in their devices then they have to get Linux and install all the related drivers on the device.
This is all about android architecture. First and foremost, I would like to express my sincere gratitude to our advisor, Mr. Prem Narayan Singh for his invaluable guidance and co-operation throughout the work. His constant encouragement and vision enabled me to take this new endeavor to the successful path. I would like to express our heartiest gratitude to Prof.
Khan, Mohammad Ali Jauhar University, Rampur for his support and encouragement throughout the work for providing the suitable environment to carry out the work. I feel compelled to articulate my thankfulness to the Coordinator, Mr. I extend our heartiest gratitude to Mr. Ishrar Ahmad, Mr. Nirabh Agarwal whose constant motivation and support made me enthusiastic throughout the work.

Android is Linux based operating system designed primarily for mobile devices such as smartphones and tablets. There are more than 4,00, apps in android market. And, android is an open source. Android is a software stack for mobile devices that includes an operating system, middleware and key applications.
Android is a software platform and operating system for mobile devices based on the Linux operating system and developed by Google and the OHA. It allows developers to write managed code in a Java-like language that utilizes Google- developed Java libraries, but does not support programs developed in native code.
Android allows to access core mobile device functionality through standard API calls. All applications are equal - Android does not differentiate between the phone's basic and third-party applications -- even the dialer or home screen can be replaced. Breaking down boundaries — Combine information from the web with data on the phone -- such as contacts or geographic location - to create new user experiences.
Fast and easy development - The SDK contains what need to build and run Android applications, including a true device emulator and advanced debugging tools.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it.
Operating systems are found on many devices that contain a computer — from cellular phones and video game consoles to web servers and supercomputers. The unveiling of the Android platform on 5 November was announced with the founding of the Open Handset Alliance, a consortium of 34 hardware, software and telecom companies devoted to advancing open standards for mobile devices.
When released in , most of the Android platform will be made available under the Apache free-software and open-source license.
Figure 1. Rubin described the Android project as "tremendous potential in developing smarter mobile devices that are more aware of its owner's location and preferences".
The early intentions of the company were to develop an advanced operating system for digital cameras, and this was the basis of its pitch to investors in April The company then decided that the market for cameras was not large enough for its goals, and by five months later it had diverted its efforts and was pitching Android as a handset operating system that would rival Symbian and Microsoft Windows Mobile.
Rubin had difficulty attracting investors early on, and Android was facing eviction from its office space. Perlman refused a stake in the company, and has stated "I did it because I believed in the thing, and I wanted to help Andy.
Its key employees, including Rubin, Miner and White, joined Google as part of the acquisition. Not much was known about the secretive Android at the time, with the company having provided few details other than that it was making software for mobile phones.
At Google, the team led by Rubin developed a mobile device platform powered by the Linux kernel. Google marketed the platform to handset makers and carriers on the promise of providing a flexible, upgradeable system. Google had "lined up a series of hardware components and software partners and signaled to carriers that it was open to various degrees of cooperation".
OHA is a business alliance of firm to develop open standard for mobile device. Open Handset Alliance includes 84 firms to develop open standard for mobile devices, i.
Figure 2. Game controllers and full-size physical keyboards are supported via Bluetooth or USB. The response to user input is designed to be immediate and provides a fluid touch interface, often using the vibration capabilities of the device to provide haptic feedback to the user. Internal hardware, such as accelerometers, gyroscopes and proximity sensors are used by some applications to respond to additional user actions, for example adjusting the screen from portrait to landscape depending on how the device is oriented, or allowing the user to steer a vehicle in a racing game by rotating the device, simulating control of a steering wheel.
The Go programming language is also supported, although with a limited set of application programming interfaces API. In May , Google announced support for Android app development in the Kotlin programming language.
When an application is not in use the system suspends its operation so that, while available for immediate use rather than closed, it does not use battery power or CPU resources. Android manages the applications stored in memory automatically: Life hacker reported in that third-party task killer applications were doing more harm than good. These are some basic features provided by android: Android is continually developed by Google and the Open Handset Alliance, and it has seen a number of updates to its base operating system since the initial release.
Versions 1. Android code names are confectionery-themed and have been in alphabetical order since 's Android 1. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities subject to security constraints enforced by the framework.
This same mechanism allows components to be replaced by the user. Underlying all applications is a set of services and systems, including: The application architecture includes the following components: These capabilities are exposed to developers through the Android application framework.
Some of the core libraries are listed below: Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the.
The Dalvik VM relies on the Linux kernel for underlying functionality such as threading and low-level memory management. At the same level there is Android Runtime, where the main component Dalvik Virtual Machine is located. It was designed specifically for Android running in limited environment, It helps to manage security, memory management, process management, network stack and other important issues.
