What is Android Platform ? It is a platform that provides tools and technologies which can used to develop and build mobile Applications. The Android platform is open and free software stack that includes an operating system, middleware services and also key applications for use on mobile devices. The Android environment uses the Linux operating system at its core. Middleware Services makes it easier for software developers to perform communication and input/output, so that developers can concentrate on the specific purpose of their application without need of concentrating on input output resource coding of device. Android provides a middleware layer including libraries that provide services such as data storage, screen display, multimedia, and web browsing. Because the middleware libraries are compiled to machine language, services execute quickly. Android also provides an application framework that developers integrate into their applications for application development.

Introduction to AndroidWhat is Android ? Mobile OS are keep on introducing from Palm OS in 1996 to Windows pocket PC in 2000
then to Blackberry OS and Android. One of the most popular used mobile OS now a days is ANDROID. There are around 2.0 lack+ games, application and widgets available on the market for
Android users. Android is a powerful Operating System supporting a large number of applications in
Smart Phones. These applications make life more comfortable and advanced for the users.
Android is a Linux-based operating system designed for mobile devices such as smartphones and tablet computers.
The Android is a light weight OS and can easily embedded into different hardware devices like networking equipment, smart TV systems including set top boxes and built in systems and various devices like as house hold appliances and wrist watches.
What is Android Platform ? It is a platform that provides tools and technologies which can used to develop and build mobile
Applications. The Android platform is open and free software stack that includes an operating
system, middleware services and also key applications for use on mobile devices. The Android environment uses the Linux operating system at its core. Middleware Services makes it easier for software developers to perform
communication and input/output, so that developers can concentrate on the specific purpose of their application without need of concentrating on input output resource coding of device. Android provides a middleware layer including libraries that provide services such as data storage, screen display, multimedia, and web browsing. Because the middleware libraries are compiled to machine language, services execute quickly.
Android also provides an application framework that developers integrate into their applications for application development.
What are the advantages of Android over other Mobile OS?1)Opensource framework, Android OS is open source and it is part of the Open Handset Alliance, most of the leading handset manufacturers in the world have Android phones.2)Uses of tools are very simple.3)Availability of Apps, majority of the apps in Google Play are free as compared to the paid apps on iPhone.4)Inbuilt support for the Flash.5) Social networking integration like with Twitter, Facebook, ..etc6)Integrated Applications & Features, Eg: Android allows an option to share, after taking a photo with the Camera.7)Free to customizes, We can customize widgets as our wish with new properties.8)Better Notification System(comprises emails, updates from various widgets.)9)Updated user interface design10) It has a better App Market, to easily upload and download.11) Different Resolutions for Different Screen Sizes.12) System wide copy and paste functionalities.13) Multitouch interfacing

14) Java Support, so can develop Robust applications.15) Multilanguage support 16) Multitask Support, i.e Android phone can run different applications simultaneously,
which obviously makes it easier to multitask and improves the overall functionality of the phone.
History of Android ? United States in October, 2003 by Andy Rubin : co-founder of Danger (Danger
Incorporation was a company exclusively in platforms, software, design, and services for mobile computing devices).
