kurze frage zum Socket bzw TCP verbindung

[mitch_HD2]

Habe folgenden Code.. hab ich irgendwo hier aus dem Forum
startet alles schön und gut..

dann hab ich noch ein Server unter Visual Basic gemacht mit Streamreader, und TCPListener.. mit meinem VB Client kann ich auf den Server nachrichten schreiben... klappt...

allerdings nicht mit meiner app..

kann es sein dass die beiden nicht miteinander arbeiten können?

Android

package com.example.chat;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.EditText;

public class MyChatCientAppActivity extends Activity {
    /** Called when the activity is first created. */
    String ip = "0";
    ChatClient client = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
         
         
         
    }
    
    public void onSendClick(View v)
    {
        EditText nachricht = (EditText) this.findViewById(R.id.EditText01);
        String msg = nachricht.getText().toString();
        client.send(msg);
        
    }
    
    public void onConnectClick(View v)
    {
        EditText AdressEditText = (EditText) this.findViewById(R.id.EditText02);
        ip = AdressEditText.getText().toString();
        int port = 4000;
        client =  new ChatClient(ip, port);
    }
}

Hast du dem Input- und Output Stream auch irgendwo gesagt, dass sie zum Socket gehören?

Entweder bin ich blind oder du hast es nicht mit im Code.

 

[mitch_HD2]

streamOut = new DataOutputStream(socket.getOutputStream());

hab ich^^
