Today, Google and the Open Handset Alliance announced the release of the entire Android software stack to the open-source world. With it, you can download the source, build it, contribute changes, and develop your own mobile device around it, free of charge (subject to the license agreement, of course). To begin, download the source and documentation at http://source.android.com.
With this move, Google has made available an entire mobile software stack to potential mobile device designers in and open and equal manner. Their goal is to open the innovation to a world-wide community, which will propel Android forward at a rate faster than any one company can do on its own. Now, the entire software stack is available for both third-party Android application developers, and mobile device and handset manufacturers alike.
As a software developer, you might like the potential of an open Android software code base, as it opens the market to new mobile applications. As a hobbyist, you might like the idea of being able to experiment with the mobile platform. As a business person, you may want to double-check the license to make sure it fits your business model. Either way, it makes sense to check out this latest move at http://source.android.com
