Google has updated their Google Play services API to version 2.0, and with it have brought one of their most requested upgrades. The new API will allow Android app developers to implement many of the new features of Google Maps directly into their apps. It will be supported on Android Froyo and beyond.
"The new API uses vector-based maps that support 2D and 3D views, and allow users to tilt and rotate the map with simple gestures." You can expect to see many new apps come out and existing maps get overhauled to make use of the new features now available. If you're a developer, you can head on over to the source link to check out the nitty-gritty of implementation.
