Google dropped Bluetooth and the GTalkService instant messaging APIs from the set of tools for the first version of the mobile phone operating system, Android 1.0, according to the Android Developers Blog. But the company made clear that handsets using the Android OS will work with other Bluetooth devices such as headsets, for example.
Dropping the Bluetooth API (application program interfaces) means software developers won’t be able to create applications that utilize Bluetooth for the Android OS. Bluetooth is a short-range radio technology that allows devices to work and communicate together wirelessly. An API is a set of tools and protocols designed to help programmers build new software applications.
