This API has been designed for Android 1.x, which has no official Bluetooth 
support for developers. If you need Bluetooth on Android 2.x, please refer to 
the official API. Otherwise, if you need to support both Android 1.x and 
Android 2.x you should have a look to "Easy Bluetooth" which is part of this 
project but it has not been included in the JAR distribution (you can find it 
browsing the SVN repository at 
http://code.google.com/p/android-bluetooth/source/browse 
/#svn%2Fbranches%2Ftwo_dot_o%2FAndroidBluetoothLibrary). Finally, the Bluetooth 
library does not work on 1.x emulator due to platform limitations.
