客户端

/********************  Client  **************************/

public void startSocket() {

}

//建立连接后，采用OutputStream进行数据的发送
sendOutStream.write(data);   //byte流数据

注意：Android中，socket的连接操作不能在主线程里面进行，必须开启新的线程；

/********************  Server  **************************/
public void startListen() {
    new Thread(this).start();
}

private final int PORT = 8088;
private ServerSocket server;

public void run() {
	//创建TCP Server 接收视频流
	Socket client;
	DataInputStream is = null;
	try {
	    server = new ServerSocket(PORT);
	    client = server.accept();
	    client.setReceiveBufferSize(500000);
	    client.setSendBufferSize(500000);
	    client.setTcpNoDelay(true);
	    client.setPerformancePreferences(0, 0, 1);
	    is = new DataInputStream(client.getInputStream());
	} catch (IOException e) {
	    e.printStackTrace();
	}

        //建立连接后开始进行读取
        byte[] data = http://www.mamicode.com/new byte[1000];>
