client Socket

I send data by socket.
I get socket.

Socket sk = null;
sk = new Socket(addr, 5000);

I prepare BufferedWriter for getOutputStream().

BufferedWriter wBuffer = null;
wBuffer = new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));

data write and flush and close for sending.

wBuffer.write("testtesttest");
Log.d("socket", "write");
wBuffer.flush();
Log.d("socket", "flush");
wBuffer.close();

I got message "testtesttest" at server side.
source code is here.
