 The Android platform is a software stack for mobile devices including an

 operating system, middleware and key applications. Developers can create

 applications for the platform using the Android SDK. Applications are 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.

 If you want to know how to develop applications for Android, you\'re in the

 right place. This site provides a variety of documentation that will help you

 learn about Android and develop mobile applications for the platform.

 An early look at the the Android SDK is also available. It includes sample

 projects with source code, development tools, an emulator, and of course all

 the libraries you\'ll need to build an Android application. What would it take

 to build a better mobile phone?
