The developers are heard: the much awaited Android SDK that powers Nexus One is finally here, available to everyone. Developers and handset manufacturers can download the latest Android development kit and begin to take advantage of the new functionality that Android 2.1 delivers. All devices that ship after January will have it by default.
That would all be fine and dandy if Google released the SDK to developers prior to launching Android 2.1, and it would seem more authentic if Google didn’t just host a major press event last week to launch its Nexus One phone–the first device built on Android 2.1, where Google trumpeted and demonstrated an array of cool new features.
The key feature of Nexus One was Android as highlighted by the Nexus one launch. Few features like the living wallpaper feature seems like a battery-wasting eye-candy. On the usability side, Android 2.1 extends the voice command functionality to allow users to speak into any text field. Though most users didn’t find it that helpful, till having is a delight for email savvy users. With 2.1 also comes a new USB driver that works for syncing or transferring files between the phone and a Windows PC.
Though Android 2.1 brings lots of new UI changes, Google says “2.1 does not add significant user features, see the Android 2.0 Platform Highlights document for the latest user features”.
