Android socket无法发送句子

Question

我正在使用Android客户端连接到Python服务器。这是我的Android客户端代码，它使用相同的无线IP地址通过移动三星迷你galaxy通过Open socket连接到服务器：

public void appendText(View view){
    Text.append( "\n  In chat ");

    try{
//  while (true)
    //{
    sentence=inputfld.getText().toString();
    String sentence1=("hohohoh");
    Text.append( "\n  DataStream creating");        
    outToServer.writeBytes(sentence);
    outToServer.writeBytes(sentence1);
    modifiedSentence = inFromServer.readLine(); 
    Text.append(modifiedSentence);
    inputfld.setText(null);

        }
        }
        catch(Exception modifiedsentence){
        Text.append("Exception");
    }


}


public void connect(View view){




                try {
                    String cmd=("My current location is: " );
                    clientSocket= new Socket("192.168.1.2",54628); 
                    Text.append( "\n created a socket");
                    outToServer = new DataOutputStream(clientSocket.getOutputStream());
                    Text.append( "\n created a datastream");
                    inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
                    Text.append( "\n created a bufferReader");
                   Text.append( "\n created a socket");


                } catch (SocketException e) {

                     e.printStackTrace();
                    }

    catch(Exception e){
        System.out.println("Error");
        }
       }

现在的问题是我可以连接并且我有按钮发送appendtext的动作事件，但是它没有让我使用手机发送。我的代码有什么问题？
