ANDROID SDK Android software development is the process by which new applications are created for the Android operating system. Applications are usually developed in the Java programming language using the Android Software Development Kit.
DESIGN Android is based on the Linux kernel, with middleware, libraries and APIs written in C and application software running on an application framework which includes Java- compatible libraries based on Apache Harmony.
FEATURES OF ANDROID
SOFTWARE FEATURES Integrated browser based on the open source Web Kit engine SQLite for relational data storage Media support for common audio, video, and still image formats Dalvik Virtual Machine optimized for mobile devices
HARDWARE FEAUTURES Cellular networking : GSM, EDGE, 3G LAN : Bluetooth, and Wi-Fi Graphics Hardware Acceleration Camera, GPS and Compass Touch screen and accelerometer for motion sensing
SECURITY Android applications run in a sandbox, an isolated area of the operating system that does not have access to the rest of the system's resources, unless access permissions are granted by the user when the application is installed.
WHAT MAKES AN ANDROID SPECIAL Open source – Free development platform Built in components can be improved Built in services like GPS,SQL Database, browser and maps Management of process life cycle High quality graphics and sound Portability across current and future hardware Component-based architecture and reusable, replaceable modules Multi-layer isolation of programs
ANDROID MARKET Google Play, formerly Android Market, is the online software store developed by Google for Android devices Market. As of October 2011 there were more than 300,000 apps available for Android, and the estimated number of applications downloaded from the Android Market as of December 2011 exceeded 10 billion.
CONCLUSION Android is open to all: industry, developers and users Participating in many of the successful open source projects Aims to be as easy to build for as the web. Google Android is stepping into the next level of Mobile Internet
