Question

Question 3

Now move the 'try' and two 'catch' blocks from the 'onCreate()' method to the 'doInBackground()' method. Leave the return statement as is, and then execute your custom async task from inside the 'onCreate()' method after 'setContentView()'.

this is what I did for code. Not sure why it will not work?

package com.example;

import android.os.Bundle;
import android.view.View;
import java.io.IOException;
import java.net.MalformedURLException;
import android.util.Log;
import android.os.AsyncTask;

public class MainListActivity extends ListActivity {

    public static final String URL = "http://www.teamtreehouse.com";
    public static final String TAG = MainListActivity.class.getSimpleName();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_list);
CustomAsyncTask CustomAsyncTask = new CustomAsyncTask();
      CustomAsyncTask.execute();

    }
      private class CustomAsyncTask extends AsyncTask<Object, Void, String>{
        @Override
protected String doInBackground(Object...params){
  return "";  
  try {
            URL treehouseUrl = new URL(URL);
            HttpURLConnection connection = (HttpURLConnection) treehouseUrl.openConnection();
            connection.connect();
            int responseCode = connection.getResponseCode();
        }
        catch (MalformedURLException e) {
            Log.e(TAG, "MalformedURLException caught!", e);
        }
        catch (IOException e) {
            Log.e(TAG, "IOException caught!", e);
      }
    }
  }
}

CustomAsyncTask CustomAsyncTask = new CustomAsyncTask();

On this line you are using the same exact name as both the class name and the variable name. Change your variable name (just use a lowercase "c") and you should be set. You can't use class names as variable names.
