Adapting Data for Display in a List Stage 4 CodeChallenge

Inside the onCreate() method, create two HashMap<String, String> variables and in each one, store a website name value using KEY_NAME as the key and the website URL value using KEY_URL as the key.

i don't understand what i'm doing wrong, help would be appriciated.

here's the code:

import android.os.Bundle;
import android.widget.SimpleAdapter;

public class WebsiteListActivity extends ListActivity {

    public static final String KEY_NAME = "name";
    public static final String KEY_URL = "url";

    public void onCreate(Bundle savedInstanceState) {

        String[] keys = { KEY_NAME, KEY_URL };
        int[] ids = { android.R.id.text1, android.R.id.text2 };
HashMap <String, String> map = new HashMap>String, String>();
      map.put(KEY_NAME, "treehouse");
      map.put(KEY_URL, "http://teamtreehouse.com/home");
        // Add code here!

Thanks for your time. Ziga :D

Create a second HashMap variable just like the one that you already have, and add another website to it. Also, make sure that all of the code that you write is below the // Add code here comment. I think that the quiz validation checks that your code is below that.
