Declare the 'doInBackground(Object... params)' method inside your custom AsyncTask. Make it 'protected', return a String, and then simply return an empty String in the body. Don't forget the '@Override' annotation on the line above the declaration!

''' 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();

  private class CustomAsyncTask extends AsyncTask<Object,Void,String>{}

public void onCreate(Bundle savedInstanceState) {

    try {
        URL treehouseUrl = new URL(URL);
        HttpURLConnection connection = (HttpURLConnection) treehouseUrl.openConnection();
        int responseCode = connection.getResponseCode();
    catch (MalformedURLException e) {
        Log.e(TAG, "MalformedURLException caught!", e);
    catch (IOException e) {
        Log.e(TAG, "IOException caught!", e);

} '''
