Google publishes Android 2.2 source code

In a brief blog post, Google has announced that it has released the entirety of the source code for Froyo, better known as Android 2.2, under an open-source license. The open-source aspect of the release isn't new -- all previous platform iterations have been open-sourced too -- but there are a few extra modules in Froyo that have been opened up that had previously been closed-source.

The announcement means that developers will get access to the nuts and bolts of the operating system, which comes with a hefty performance boost over previous versions, along with a host of other features that include cloud-to-device messaging, portable Wi-Fi hotspot functionality and a doubling of the camera's framerate.
