Question

由于我不知道的原因，我无法在Android（4.2）和我的电脑之间建立连接。相同的代码适用于我的同事...

服务器代码如下（相关部分）：

private static List<Socket> socketList = Collections.synchronizedList(new ArrayList<Socket>());  
private ExecutorService exec;     
private ServerSocket server;  

public static void main(String[] args) {     
    new AndroidServer();     
}     

public AndroidServer() {  
    try {  
        server = new ServerSocket(80);  

        exec = Executors.newCachedThreadPool();  
        Socket client = null;  
        while (true) {  
            client = server.accept();
            System.out.println("hello")
            socketList.add(client);   
            exec.execute(new ChatTask(client));     
        }     
    } catch (IOException e) {     
        e.printStackTrace();  
    }  
}

客户端代码（在Android手机上）看起来像这样（有点乱，对不起）：

try {
    String IP_ADDRESS = "123.123.123.123";
    socket = new Socket(IP_ADDRESS, 80);

    exec.execute(new Sender(socket));
    userId = socket.getInetAddress() + ":" + socket.getLocalPort();

    println("[" + userId + "] is connected with Android Server");

    BufferedReader br=new BufferedReader(new InputStreamReader(socket.getInputStream()));

    PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);

    String mstr = br.readLine();
    if (mstr != null) {
        text1.setText(mstr); //text1 is a text field in the Android view
    } else {
        text1.setText("");
    }
    out.close();
    br.close();
    socket.close();
} 

static class Sender implements Runnable{ 
private Socket socket;

public Sender(Socket socket){
    this.socket = socket;
}

@Override
public void run() {
    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));     
        PrintWriter pw = new PrintWriter(socket.getOutputStream(), true);
        String msg; 

    while (true) {                    
        msg = br.readLine();  
        if (msg.length() == 0)
            {  
                print(socket.getLocalPort()+":>");  
            } else {  
                pw.println(msg);  
                continue;  
        }  
        [some code skipped]
        }  
        pw.close();  
        br.close();  
        socket.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

Android源码的AndroidManifest.xml如下所示：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="net.testSocket"
    android:versionCode="1"
    android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".TestSocket"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
