使用套接字時發生錯誤io

我正在使用由gottox編寫的Java的Socket.IO-Client for android應用程序。我試圖使用該庫將消息發送到由node.js製作的服務器並從中接收響應，但是我得到這些警告使用套接字時發生錯誤io

這裏是我的代碼

tv=(TextView)findViewById(R.id.textView1); 
     SocketIO socket=new SocketIO(); 
     try { 
      socket = new SocketIO("http://41.69.21.123:1333/"); 
     } catch (MalformedURLException e1) { 
      // TODO Auto-generated catch block 
      e1.printStackTrace(); 
     } 
     socket.connect(new IOCallback() { 
      public void onMessage(JSONObject json, IOAcknowledge ack) { 
       try { 

        tv.setText(json.toString(2)); 
       // System.out.println("Server said:" + json.toString(2)); 


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

      public void onMessage(String data, IOAcknowledge ack) { 
       //tv.setText(data); 
       //System.out.println("Server said: " + data); 
      } 

      public void onError(SocketIOException socketIOException) { 
       //tv.setText(socketIOException.toString()); 
       //System.out.println("an Error occured"); 

       socketIOException.printStackTrace(); 
      } 

      public void onDisconnect() { 
      // tv.setText("Connection terminated."); 
       //System.out.println("Connection terminated."); 
      } 

      public void onConnect() { 
      // tv.setText("Connection terminated."); 
       // System.out.println("Connection established"); 
      } 

      public void on(String event, IOAcknowledge ack, Object... args) { 
       //tv.setText("Server triggered event '" + event + "'"); 
       // System.out.println("Server triggered event '" + event + "'"); 
      } 
     }); 

     // This line is cached until the connection is establisched. 
     socket.send("Hello Server!"); 

    //  SocketIO socket=new SocketIO("http://127.0.0.1:3001/"); 

    }

要初始化插座兩次樣本。

此：

... 
SocketIO socket=new SocketIO(); 
try { 
    socket = new SocketIO("http://41.69.21.123:1333/"); 
...

應該是這樣的：

... 
SocketIO socket; 
try { 
    socket = new SocketIO("http://41.69.21.123:1333/"); 
...
