Via my coworkers at the Android Developers Blog : Android is now open source . Android is the first free, open source, and fully customizable mobile platform. Android offers a full stack: an operating system, middleware, and key mobile applications. It also contains a rich set of APIs that allows third-party developers to develop great applications. Across my career, I am most proud of Android—as a platform, as a family of phones, and as a catalyst for change in an otherwise closed industry. But the most exciting part is what's next. Download the SDK and start hacking.
Download the Android SDK 1.0 release 1 . Walt Mossberg : "The first real competitor to the iPhone ... the software is slick ... the G1 is a powerful, versatile device." But the sui generis : Android is open to developers, open to consumers, and open to handset manufacturers. Cannot wait to see what's next.
