This is the first release of the Android SDK that is formally on the path to Android 1.0. The release is considered beta. (Previous releases were considered early looks at the SDK, and were not formally on the path toward Android 1.0.) This release may not be fully compatible with Android 1.0, when released, meaning that applications you build using this SDK may not run on final Android 1.0 devices.
