Hi all,

I am using this code but it gives errors i am unable to trace.Any help would be appreciated.Here is the code:

package com.example.test;

import java.net.DatagramPacket;
import java.net.DatagramSocket;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;



public class MainActivity extends Activity {
	
	TextView display;

	private MyDatagramReceiver myDatagramReceiver = null;
	
	
	protected void onResume() {
	    myDatagramReceiver = new MyDatagramReceiver();
	 
	   myDatagramReceiver.start();
	  
	}
	

	protected void onPause() {
	  //  myDatagramReceiver.kill();
	}
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		display=(TextView) findViewById(R.id.textView1);
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		
		
		return true;
	}

	private class MyDatagramReceiver extends Thread {
	    private boolean bKeepRunning = true;
	    private String lastMessage = "";

	    public void run() {
	        String message;
	        byte[] lmessage = new byte[100];
	        

	        try {
	            DatagramSocket socket = new DatagramSocket(2690);
	            Log.v("Run", "Socket Created");
	            while(bKeepRunning) {
	            	DatagramPacket packet = new DatagramPacket(lmessage, lmessage.length);
	                socket.receive(packet);
	                message = new String(lmessage, 0, packet.getLength());
	                lastMessage = message;
	                runOnUiThread(updateTextMessage);
	                Log.v("Receiving", "packet recvd");
	            }
	            
	            if (socket != null) {
	 	           socket.close();
	 	          Log.v("SOC", "Socket closed");
	 	       }
	        } catch (Throwable e) {
	            e.printStackTrace();
	        }

	       
	    }

	    public void kill() { 
	        bKeepRunning = false;
	    }

	    public String getLastMessage() {
	        return lastMessage;
	    }
	}

	private Runnable updateTextMessage = new Runnable() {
	    public void run() {
	        if (myDatagramReceiver == null) return;
	        display.setText(myDatagramReceiver.getLastMessage());
	    }
	};
	
}

Following are the errors:
