I don't understand how I should name the two Strings

I don't understand how I should name the two Strings

Challenge: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>{};

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

    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);
    }
}

} '''

Hi Florin, you don't really need to name the string. It says....

"Make it 'protected', return a String,

This asks you to set the return type to be a string.. like this:

       @Override
        protected String doInBackground(Object ... params){ 
           //above we set the return type to String     
        }

and then simply return an empty String in the body"

what this asks, is that you return an empty string in the body of the previous function, like this:

       @Override
        protected String doInBackground(Object ... params){
          return ""; //here we return an empty String
        }

I hope this clears things out for you :)

Thank you Gloria! - Make it 'protected', return a String - This part was confusing for me.
