Android Application Development Service

The android development platform is a software stack for mobile devices including an operating system, middle-ware and key applications. Android applications can be created for the platform using the android sdk and written using the java programming language and run on dalvik, a custom virtual machine designed for embedded use, which runs on top of a linux kernel.
android is stressing the open nature of the platform. Operating systems on current phones - such as windows mobile, rim, symbian and palm - are proprietorial and have to be licensed for use. Google believes it will be easier and quicker to develop new applications for android than the other systems.
