Question

我正在开发将连接到我的电脑的Android客户端。虽然我在模拟器上测试它，但它工作正常。但是，当我在真实设备上尝试它时，我得到套接字超时异常。

以下是相关的客户代码

public static final String SERVER_IP = "192.168.1.105"; //your computer IP address
public static final int SERVER_PORT = 500;

...

try {
        //here you must put your computer's IP address.
        InetAddress serverAddr = InetAddress.getByName(SERVER_IP);

        Log.e("TCP Client", "C: Connecting...");

        //create a socket to make the connection with the server
        Socket socket = null;
        try {
            //Here i am geting the exception
            socket = new Socket(serverAddr, SERVER_PORT); 
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

这是服务器代码

public class FileServer {
public static void main (String [] args ) throws Exception {
    // create socket
    final int SERVER_PORT = 500;

    System.out.println("Open port "+ SERVER_PORT);
    ServerSocket servsock = new ServerSocket(SERVER_PORT);

    final String FILE_NAME ="C:\\myImages\\Movie-Line.CSV"; 
    File myFile = new File (FILE_NAME);
    System.out.println("File to send "+ FILE_NAME);

    while (true) {
        System.out.println("Waiting...");

        Socket sock = servsock.accept();
        System.out.println("Accepted connection : " + sock);
        OutputStream os = sock.getOutputStream();
        new FileServer().send(os,myFile);
        sock.close();
    }
}

public void send(OutputStream os,File myFile) throws Exception{


    FileInputStream fis = new FileInputStream(myFile);
    BufferedInputStream bis = new BufferedInputStream(fis);
    int counter;
    byte[] buffer = new byte[1024];

    while((counter = bis.read(buffer))!=-1) 
        os.write(buffer,0,counter);

    os.flush();
    bis.close();

这是我的日志
