Android Socket实现无法正常工作

Question

我有一个简单的服务器：

public class MyServer {
    public static void main(String[] args) throws IOException {
        ServerSocket ss;
        Socket client;
        ss = new ServerSocket(8888);
        System.out.println("Server socket created");
        client = ss.accept();

        Scanner in = new Scanner(client.getInputStream());
        while(in.hasNextLine()) {
            System.out.println(in.nextLine());          
        }
        in.close();        
    }

}

我正在尝试从Android手机连接到该服务器。我已在我的宣言中设置了所有必需的权限 - INTERNET和ACCESS_NETWORK_STATE。这是我的AsyncTask。我已经尝试创建任务对象并在OnCreate（）中调用其execute（）方法，但它没有连接。我得到一个超时说我无法找到服务器，但我尝试从具有相同IP的另一台PC连接到服务器，它的工作原理。有什么想法吗？

class MyTransmitter extends AsyncTask<String, Void, List<Address>> {
    private static Socket mytransmitter;
    private static PrintWriter out;
    private static boolean firstReport = true;
@Override
protected List<Address> doInBackground(String... params) {
    System.out.println("AsyncTask is being executed");
    try {           
        if (firstReport) {              
            System.out.println("About to try create a socket!");
            InetAddress serverAddr = InetAddress.getByName("155.245.119.5");
            mytransmitter = new Socket(serverAddr, 8888);
            out = new PrintWriter(mytransmitter.getOutputStream());
            out.println("TimeStamp: " + getCurrentTimeStamp() + "; GPS_latitude: " + params[0] + "; GPS_longitude: " + params[1] + "; Speed: " + params[2] + ";");
            System.out.println("TimeStamp: " + getCurrentTimeStamp() + "; GPS_latitude: " + params[0] + "; GPS_longitude: " + params[1] + "; Speed: " + params[2] + ";");
            out.flush();
            firstReport = false;
        }
        else {
            out.println("TimeStamp: " + getCurrentTimeStamp() + "; GPS_latitude: " + params[0] + "; GPS_longitude: " + params[1] + "; Speed: " + params[2] + ";");
            System.out.println("TimeStamp: " + getCurrentTimeStamp() + "; GPS_latitude: " + params[0] + "; GPS_longitude: " + params[1] + "; Speed: " + params[2] + ";");
            out.flush();                
        }

    } catch (UnknownHostException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }           
    return null;
}
