There's a range of improvements, the most impressive being the expansion of mapping services to include forward and reverse geocoding as well as business lookups. This feature plugs a big hole in the LBS and mapping functionality previously available in Android.
Other improvements include a new iteration of the still-being-worked-on Android GUI (screen shots here), a new Animation class for creating animations in layouts, and an improved MediPlayer class that supports additional audio formats.
Also, while I've been away getting married for the last month there's been a few important Android annoucements. Here's a quick summary of what's been announced so far this year:
- LG have joined Samsung in committing to releasing an Android compatible phone towards the end of 2008 / start of 2009.
- The Android Developer Challenge has been extended until April 14.
- You can now file bugs against the Android SDK.
