Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all handset has to offer. It was built to be truly open. For example, an application can call upon any of the phone’s core functionality such as making calls, sending text messages, or using the camera, allowing developers to create richer and more cohesive experiences for users. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that was designed to optimize memory and hardware resources in a mobile environment. Android is open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications .
Introduction
Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using t he J ava programming language. Android is based up on a modified version of the Linux kernel. Google and other members of the Ope n Handset Alliance collaborated on Android’s development and release. Android has a large community of developers writing application programs (“apps”) that extend the functionality of the devices. There are currently over 200,000 apps available for Android. Android Market is the online app s to re run by Google, though apps can also be downloaded from third-party sites. Developers write primarily in t he Java language, controlling the device via Google-developed Java libraries. The Android OS can be used as an operating system for cell phones, netbooks and tablets, including the Dell Streak, Samsung Galaxy Tab, TV and other devices.
