Android通過Socket(TCP/IP)與PC通訊

Java Server 源代碼： [java]   public class TCPDesktopServer implements Runnable{           public static final String SERVERIP = "192.168.0.149";          public static final int SERVERPORT = 51706;           public void run() {               try {                   System.out.println("S: Connecting...");                    ServerSocket serverSocket = new ServerSocket(SERVERPORT);                   while (true) {                         Socket client = serverSocket.accept();                     System.out.println("S: Receiving...");                         try {                            BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));                            String str = in.readLine();                            System.out.println("S: Received: '" + str + "'");                          } catch(Exception e) {                              System.out.println("S: Error");                              e.printStackTrace();                          } finally {                              client.close();                              System.out.println("S: Done.");                          }                    }                } catch (Exception e) {                   System.out.println("S: Error");                   e.printStackTrace();               }          }          public static void main (String a[]) {              Thread desktopServerThread = new Thread(new TCPDesktopServer());              desktopServerThread.start();          }   }     對上邊的源代碼做一些介紹： 指定Server監聽的端口和服務器IP地址。 [java]   public static final String SERVERIP = "192.168.0.149";      public static final int SERVERPORT = 51706;     應用之前所指定的IP和Port創建一個ServerSocket對象。   [java]   ServerSocket serverSocket = new ServerSocket(SERVERPORT);   用於偵聽和捕捉通過Socket連接的客戶端。 [java]   Socket client = serverSocket.accept();   應用Socket創建BufferedReader對象,用於接收Socket Stream中的數據。 [java]   BufferedReader in = new BufferedReader(newInputStreamReader(client.getInputStream()));   Android Client 源代碼： [java]   InetAddress serverAddr = InetAddress.getByName("192.168.0.149");//TCPServer.SERVERIP      Log.d("TCP", "C: Connecting...");      Socket socket = new Socket(serverAddr, 51706);      String message = "AndroidRes,Where is my Pig (Android)?";      try {          Log.d("TCP", "C: Sending: '" + message + "'");          PrintWriter out = new PrintWriter( new BufferedWriter( newOutputStreamWriter(socket.getOutputStream())),true);              out.println(message);      } catch(Exception e) {              Log.e("TCP", "S: Error", e);      } finally {          socket.close();      }   對上邊的源代碼做一些介紹： 指定Server的IP地址。 [java]  InetAddress serverAddr = InetAddress.getByName("192.168.0.149");<span style="font-family:Consolas,'Bitstream Vera Sans Mono','Courier New',Courier,monospace; color:#000000; font-size:16px; white-space:normal"> </span>   應用Server的IP和端口建立Socket對象。 [java]   Socket socket = new Socket(serverAddr, 51706);<span style="font-family:Consolas,'Bitstream Vera Sans Mono','Courier New',Courier,monospace; color:#000000; font-size:16px; white-space:normal"> </span>   根據已經建立的Socket來創建PrintWriter，將信息通過這個對象來發送給Server，其中包含了三個部分： [java]  OutputStreamWriter   BufferedWriter   PrintWriter   [java]   PrintWriter out = new PrintWriter( new BufferedWriter( newOutputStreamWr
