Android - An Open Handset Alliance Project

Welcome to Android!

New Android SDK!

We've just released the Android 1.0 SDK! If you're using a previous version of the SDK, there will be some work required to upgrade your development environment and make your applications properly run on the new version of the Android platform.

Please read the upgrade instructions and then the API changes overview.

For even more details on the changes, there is an API differences report.

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.

A beta version of the Android SDK is available for download. Along with the Android framework and application libraries, it includes sample projects with source code, a device emulator, and development tools for monitoring and debugging your code and GUI layout.
