The new release notes of Google's Android 0.9 SDK Beta R1 unveil there will be no support for Bluetooth in the first Android operating system:
Due to significant API changes in the upstream open-source project and due to the timeline of getting certain Bluetooth profile implementations certified, a comprehensive Bluetooth API will not be possible or present in Android 1.0.
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. However, the differences between this release and final 1.0-compatible releases are expected to be small. No major API changes are planned.
