Set socket opt failed bad file number exception

Am getting set socket option failed exception in Android. What am I doing wrong ?

    setsockopt failed: EBADF (Bad file number)

For the following code:

int timeout = 500;



Socket socket = new Socket(InetAddress.getByAddress(new byte[]{10, 0, 2, 2}),
                            Integer.parseInt(m.destPort));
                    ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
                    oos.writeObject(m);
                    oos.close();
                    socket.setSoTimeout(timeOut);
                    ObjectInputStream iis = new ObjectInputStream(socket.getInputStream());
                    iis.readObject();
                    iis.close();
                    socket.close();

Closing the input or output stream of a socket closes the other stream and the socket.

Change

oos.close();

to

oos.flush();

(Poor coding in Android. It should throw a SocketException: socket closed.)
