Android Operating System :
- ( It’s a open source platform developed under the open handset alliance to unable faster development of mobile applications and provision of services to the users.)
- is a Linux-based operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers.
HISTORY
Android was founded in Palo Alto, California in October 2003 by Andy Rubin (co-founder of Danger),Rich Miner (co-founder of Wildfire Communications, Inc.), Nick Sears (once VP at TMobile), and Chris White (headed design and interface development at WebTV). The early intentions of the company were to develop an advanced operating system for digital cameras, when it was realised that the market for the devices was not large enough, and diverted their efforts to producing a smartphone operating system to rival those.
VERSIONS OF ANDROID :
Since 2008, Android has seen numerous updates which have incrementally improved the operating system, adding new features and fixing bugs in previous releases. Each major release is named in alphabetical order after a dessert.
Google launched its Nexus series of devices-a line of smartphones and tablets running the Stock Android operating system, and built by a manufacturer partner. HTC collaborated with Google to release the first Nexus smartphone,the Nexus One. The series has since been updated with newer devices, such as the Nexus 4 phone and Nexus 10 tablet.
INTERFACE:
Android's user interface is based on direct manipulation, using touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching and reverse pinching to manipulate on-screen objects. Android home screens are typically made up of app icons and widgets.
APPLICATIONS :
Android has a growing selection of third party applications, which can be acquired by users either through an app store such as Google Play or by downloading and installing the application's APK file from a third-party site. Purchases of unwanted applications can be refunded within 15 minutes of the time of download. As of September 2012, there were more than 6,75,000 apps available for Android, and the estimated number of applications downloaded from.
USERS can also purchase Chromebooks, Google Nexus mobile devices BRAND, other Google-branded hardware, AND ACCESSORY Google Play.
DEVELOPMENT OF APPS :
Applications are developed in the Java language using the Android software development kit (SDK). The SDK includes a comprehensive set of development tools, including a debugger, software libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials. The officially supported integrated development environment (IDE) is Eclipse using the Android Development Tools (ADT) plug-in.
OPEN-SOURCE COMMUNITY:
Android has an active community of developers and enthusiasts who use the Android source code to develop and distribute their own modified versions of the operating system. These community-developed releases often bring new features and updates to devices faster than through the official manufacturer/carrier channels, albeit without as extensive testing or quality assurance; provide continued support for older devices that no longer receive official updates; or bring Android to devices that were officially released running other.
Google currently uses their Google Bouncer malware scanner to watch over and scan the Google Play store apps. It is intended to flag up suspicious apps and warn users of any potential issues with an application before they download it.
SECURITY AND PRIVACY:
Android applications run in a sandbox, an isolated area of the system that does not have access to the rest of the system's resources, unless access permissions are explicitly granted by the user when the application is installed. Before installing an application, the Play Store displays all required permissions, for example, a game may need to enable vibration or save data to an SD card, but should not need to read SMS messages or access the phonebook.
BEYOND SMARTPHONES AND TABLETS:
The open and customizable nature of Android allows it to be used on other electronics, including laptops and netbooks, smartbooks smart TVs(Google TV) and cameras (Nikon Coolpix S800c and Galaxy Camera). In addition, the Android operating system has seen applications on smart glasses (Google Glass), wristwatches, portable media players. Ouya, a video game console running Android, became one of the most successful and was later followed by other Androidbased video games consoles such as Project Shield from Nvidia.
