Android, a product of Open Handset Alliance (OHA) is a complete package of software for mobile devices. It is comprised of an operating system, middleware and mobile applications. The android operating system runs on open Linux kernel. It contains a set of APIs (Application Programming Interface) and libraries that gives users enormous facility to innovate new applications, for example: a developer can combine information from the web with data on an individual’s mobile phone — such as the user’s contacts, calendar, or geographic location. A developer can build an application that enables users to view the location of their friends and be alerted when they are in the vicinity giving them a chance to connect.
Android provides a software development kit (SDK) which is constituted of debugger, libraries, a handset emulator (based on QEMU), documentation, sample code, and tutorials.
Key features of an Android operating system:
Handset Layout>: The platform is adaptable to VGA, 2D graphics library, 3D graphics library based on OpenGL ES 1.0 specifications, and traditional Smartphone layouts.
Storage: The Database Software SQLite is used for data storage purposes
Connectivity: Android supports connectivity technologies including GSM/EDGE, CDMA, EV-DO, UMTS, Bluetooth and Wi-Fi.
Messaging: SMS and MMS are available forms of messaging including threaded text messaging.
Web browser: The web browser available in Android is based on the open-source WebKit application framework.
Media support: Android supports the following audio/video/still media formats: MPEG-4, H.264, MP3, AAC, MIDI, OGG, AMR, JPEG, PNG, GIF.
Additional hardware support: Android can utilize video/still cameras, touch screens, GPS, accelerometers, magnetometers, accelerated 2D (with hardware orientation, scaling, and pixel format conversion) and accelerated 3D graphics.
Development environment: Includes a device emulator, tools for debugging, memory and performance profiling, a plug-in for the Eclipse IDE.
Market: The Android Market is a store house of applications that can be downloaded and installed .Originally only freeware applications were supported. Paid-for applications have been available on the Android Market in the United States since 19 February 2009.

The latest entry in OHA is Acer.
Android is available as an entirely open source since October 21, 2008. Despite of the fact that it is an open source product, there are few developments happening in the product in a private development branch named ‘Cupcake’ (Its a read-only mirror branch for public view). This development activity will result in changes in download manager, the framework, Bluetooth, the system software, radio and telephony, developer tools, the build system and several applications, as well as a number of bug fixes.
On 30th April, 2009 another milestone was achieved with the release of 1.5 update for Android which led to following enhancements:
• Ability to record and watch videos with the camcorder mode
• Uploading videos to YouTube and pictures to Picasa directly from the phone
• A new soft keyboard with an “Autocomplete” feature
• Ability to automatically connect to a Bluetooth headset within a certain distance
• New widgets and folders that can populate the desktop
• Animations between screens
• Expanded ability of Copy and paste to include web pages.
