Why does my app keep crashing after it shows up on the Emulator? I just started learning about Jsoup parsing and following different tuts, but I can't find solution to this error.

My code is given below:

package com.example.testingjson;

import java.io.IOException;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;


public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// process

Document doc;
try {
doc = Jsoup.connect("http://google.com/").get();
String title = doc.title();
System.out.print(title);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}





And this is the Error Message
