-/**
- * The Android Bluetooth API is not finalized, and *will* change. Use at your

- *
- * This class implements an API to the Bluetooth RFCOMM layer. An RFCOMM socket
- * is similar to a normal socket in that it takes an address and a port number.
- * The difference is of course that the address is a Bluetooth-device address,
- * and the port number is an RFCOMM channel. The API allows for the
- * establishment of listening sockets via methods
- * {@link #bind(String, int) bind}, {@link #listen(int) listen}, and
- * {@link #accept(RfcommSocket, int) accept}, as well as for the making of
- * outgoing connections with {@link #connect(String, int) connect},
- * {@link #connectAsync(String, int) connectAsync}, and
- * {@link #waitForAsyncConnect(int) waitForAsyncConnect}.
- *
- * After constructing a socket, you need to {@link #create() create} it and then
- * {@link #destroy() destroy} it when you are done using it. Both
- * {@link #create() create} and {@link #accept(RfcommSocket, int) accept} return
- * a {@link java.io.FileDescriptor FileDescriptor} for the actual data.
- * Alternatively, you may call {@link #getInputStream() getInputStream} and
- * {@link #getOutputStream() getOutputStream} to retrieve the respective streams
