Android开发之服务器与客户端搭建

新建Java工程：

1.服务器：

try {//创建套接字，ip,端口号ServerSocket socket = new ServerSocket(8801);System.out.println("socket套接字创建成功");//客户端接入while(true){final Socket con = socket.accept();System.out.println("客户端接入");new Thread(new Runnable() {public void run() {// TODO Auto-generated method stubInputStream in;try {byte[] data = new byte[128];int len = 0;//获取输入流，用来读取数据in = con.getInputStream();len = in.read(data);System.out.println("read data:"+new String(data,0,len));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}).start();}} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}

2.客户端：

try {Socket client = new Socket("192.168.1.3",8801);//获得数据发送通道OutputStream out = client.getOutputStream();Scanner sc = new Scanner(System.in);String message = sc.next();out.write(message.getBytes());//获取数据接收通道InputStream in = client.getInputStream();int len;byte[] data = new byte[128];len = in.read(data);System.out.println("服务器返回数据:"+new String(data,0,len));}  catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}

3.安卓客戶端

 public void sendMessageHandler(){try {Socket client = new Socket("192.168.1.3",8801);//获得数据发送通道OutputStream out = client.getOutputStream();String message = "message from android:";//发送数据out.write(message.getBytes());//获取数据接收通道InputStream in = client.getInputStream();int len;byte[] data = new byte[128];len = in.read(data);System.out.println("服务器返回数据:"+new String(data,0,len));}  catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

 public void sendMessage(View v){new Thread(new Runnable() {@Overridepublic void run() {// TODO Auto-generated method stubsendMessageHandler();}});}

安卓Socket客户端开发注意事项：

网络访问不能在主线程（UI线程）中进行，否则程序会崩溃

要创建线程来发起网络访问
