JSON parsing error google map place api

Hello again this is my second question in SO. This is my first question. The answer given by the guys are really helpful so i tried to implements it.And here is my implementation..

Making a JSONFunction class with a static method whcch will return the json Object.

public class JSONFunction {

public static JSONObject getJSONfromURL(String url){
    InputStream is = null;
    String result = "";
    JSONObject jArray = null;

    //http post
    try{
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

    }catch(Exception e){
            Log.e("log_tag", "Error in http connection "+e.toString());
    }

  //convert response to string
    try{
            BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
            }
            is.close();
            result=sb.toString();
    }catch(Exception e){
            Log.e("log_tag", "Error converting result "+e.toString());
    }

    try{

        jArray = new JSONObject(result);            
    }catch(JSONException e){
            Log.e("log_tag", "Error parsing data "+e.toString());
    }

    return jArray;
}
}

NOW MY MAIN ACTIVITY is..

public class JsonExampleActivity extends ListActivity {
/** Called when the activity is first created. */
JSONFunction JSONfunction;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listplaceholder);

    ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();


    JSONObject json = JSONFunction.getJSONfromURL("https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=1000&types=resturants&sensor=false&key=0bBgLl42nWwl7TQHrAFpY89v2FeLlijIGTLJ1AA");

    try{
        JSONObject httpattributr= json.getJSONObject("html_attributions");
        //JSONObject results =new JSONObject("results");
        JSONArray  JArray = httpattributr.getJSONArray("results");

        for(int i=0;i<JArray.length();i++){                     
            HashMap<String, String> map = new HashMap<String, String>();    
            JSONObject e = JArray.getJSONObject(i);
            map.put("id",  String.valueOf(i));
            map.put("name", "" + e.getString("name"));
            map.put("type", "type: " +  e.getString("type"));
            mylist.add(map);            
        }       
    }catch(JSONException e)        {
         Log.e("log_tag", "Error parsing data "+e.toString());
    }

    ListAdapter adapter = new SimpleAdapter(this, mylist , R.layout.main, 
                    new String[] { "name", "type" }, 
                    new int[] { R.id.item_title, R.id.item_subtitle });

    setListAdapter(adapter);

    final ListView lv = getListView();
    lv.setTextFilterEnabled(true);  
    lv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {              
            @SuppressWarnings("unchecked")
            HashMap<String, String> o = (HashMap<String, String>) lv.getItemAtPosition(position);                   
            Toast.makeText(JsonExampleActivity.this, "ID '" + o.get("id") + "' was clicked.", Toast.LENGTH_SHORT).show(); 

        }
    });
}
}

But i am getting error in logcat as

11-04 19:56:53.099: ERROR/log_tag(298): Error parsing data org.json.JSONException: JSONObject["html_attributions"] is not a JSONObject.

Any help would be highly appreciated
Thanks in advance.

The JSON result is look like

  {
"html_attributions" : [
"Listings by \u003ca href=\"http://www.yellowpages.com.au/\"\u003eYellow Pages\u003c/a\u003e"
  ],

  "geometry" : {
    "location" : {
      "lat" : -33.8719830,
      "lng" : 151.1990860
    }
  },
    "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/restaurant-71.png",
    "id" : "677679492a58049a7eae079e0890897eb953d79b",

Change

JSONObject httpattributr= json.getJSONObject("html_attributions");
JSONArray  JArray = httpattributr.getJSONArray("results");

to

JSONArray httpattributr= json.getJSONArray("html_attributions");
JSONArray  JArray = json.getJSONArray("results");

EDIT: The result array isn't a child of or element in the html_attributions array - they are siblings.

"html_attributions" key has JSONArray as it's value, so instead of 

JSONObject httpattributr= json.getJSONObject("html_attributions");

try using...

JSONArray httpattributtr = json.getJSONArray("html_attributions");

In the json that you're parsing, there must not be a key named "html_attributions". What does your json look like?
