android手机与PC通信 socket

[帅气好男人_Jack]

在同一个局域网内（WIFI），利用socket实现手机与PC通信，手机client，PC为server，问题一直处在第一步的TCP连接（即客户端卡在new socket(IP,port)，服务端卡在socket = serversocket.accpet()）这里，检查了client的访问wifi权限和网络权限都打开了，代码也正常，可就是抛出连接超时异常结束;
错误信息：


以下是我的socket代码;
Client：
主线程:

public class MainActivity extends Activity implements OnClickListener{
	private static final String TAG = "AC";
	private EditText msg;
	private TextView content;
	private Button send,closed;
	InetAddress inet;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
        Log.i(TAG, NetType(this));
        new ThreadNet().start();
       
        
    }
//子线程模拟客户端
package com.example.connection;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

import android.util.Log;

public class ThreadNet extends Thread{
	private static final String TAG = "ThreadNet";
	private static final String path = "192.168.1.102";
	private static final int PORT = 54321;
	private Socket socket;
	
	public ThreadNet(){	
	}
	
	@Override
	public void run() {
		// TODO Auto-generated method stub
		
		String str = "i com from android device!";
		OutputStream out = null;
		InputStream in = null;
		try {
			Log.i(TAG, "11111111111 ");
			socket = new Socket(path,PORT);    // ////////程序卡在这个地方，一直在尝试连接
			Log.i(TAG, "2222222222222 ");
			out = socket.getOutputStream();
			byte[] buffer = str.getBytes();
			out.write(buffer);
			Log.i(TAG, "33333333333 ");
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			Log.i(TAG, "MSG: "+e.toString());
		}finally{
			if(out != null){
			try {
				out.close();
				out = null;
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			}
			if(socket != null){
				try {
					socket.close();
					socket = null;
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}
	}
}

Server端：

public class HttpClient {
	private static final int PORT = 54321;
	//main方法
	public static void main(String[] args){
		mServer();
	}
	
	public static void mServer(){
		ServerSocket sSocket = null;
		InputStream in = null;
		OutputStream out = null;
		Socket socket = null;
		byte[] buffer = new byte[1024];
		String str = null;
		
		try {
			sSocket = new ServerSocket(PORT);
			System.out.println("11111111======");
			socket = sSocket.accept();      /////服务端一直停在这里了
			System.out.println("-222222======");
			in = socket.getInputStream();
			int len = 0;
			System.out.println("----======");
			while((len = in.read(buffer)) != -1){
				str = new String(buffer,0,len);
				System.out.print(str);
			}
		} catch (Exception e) {
			// TODO Auto-generated catch block
			System.out.println("234: "+ e.toString());
		}finally{
			if(in != null){
				try {
					in.close();
					in = null;
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
			if(socket != null){
				try {
					socket.close();
					socket = null;
				} catch (IOException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				
			}
		}
	}
	

客户端的权限：

	<uses-permission android:name="android.permission.ACCESS_WIFI_STAT"/>
	<uses-permission android:name="android.permission.INTERNET"/>
	<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
	<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
	<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>

代码很简单，可就是一直通不了，求见解，解决方案；IP这些都是对的

换个端口试下

引用 1 楼 mmorss的回复:

换个端口试下

端口换过 一样的效果

[我是纸老虎]

把超时时间设置长一些 试试 ，或者使用HttpClient

楼主解决了吗？我也是这个问题
