Android socket can't send sentence

I'm using an Android client to connect to a Python server. here is my Android client code, which connects via mobile Samsung mini galaxy to the sever via Open socket using same wireless IP address:

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 sock开发者_开发技巧et");


                } catch (SocketException e) {

                     e.printStackTrace();
                    }

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

The problem now is that I can connect and I have button to send on action event for appendtext, but it didn't let me send using the mobile. What is wrong in my code?
