HI
Could some one let me know were i am going wrong as i am not able to
successfully establish a connection between Android and desktop server
pc .
My android client program is
package com.example.socketandroid;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class SocketAndroid extends Activity {
EditText textOut;
TextView textIn;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
textOut = (EditText)findViewById(R.id.textout);
Button buttonSend = (Button)findViewById(R.id.send);
textIn = (TextView)findViewById(R.id.textin);
buttonSend.setOnClickListener(buttonSendOnClickListener);
}
Button.OnClickListener buttonSendOnClickListener = new
Button.OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Socket socket = null;
DataOutputStream dataOutputStream = null;
DataInputStream dataInputStream = null;
try {
socket = new Socket("192.168.2.4", 5000);
dataOutputStream = new DataOutputStream(socket.getOutputStream());
dataInputStream = new DataInputStream(socket.getInputStream());
dataOutputStream.writeUTF(textOut.getText().toString());
textIn.setText(dataInputStream.readUTF());
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
if (socket != null){
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (dataOutputStream != null){
try {
dataOutputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (dataInputStream != null){
try {
dataInputStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}};
}
The server program
import java.io.*;
import java.net.*;
public class server {
/** Main entry point */
public static void main(String args[]) throws Exception {
System.out.println("ServerRead is waiting for requests on port
50000 ...");
// Create a listening Server Socket
ServerSocket ss = new ServerSocket(5000);
// Wait in a loop for connection requests
Socket sCon = ss.accept(); //
Wait...
// Get an Input Stream
InputStream in = sCon.getInputStream();
// Read in a loop from Socket and write to console
int c;
while((c = in.read()) != -1)
System.out.write(c);
// Clean up
sCon.close();
ss.close();
}
}
Have also set the permission in the manifest file
<uses-permission android:name="android.permission.INTERNET" />
also tried the
adb forward tcp:5000 tcp:5000
still no joy.
