An example below demonstrates how to parse JSON. You will get a very clearcut explanation about json parsing here.

JSONObject myjson = new JSONObject("put you json string here");
JSONArray the_json_array = myjson.getJSONArray("0");
int size = the_json_array.length();
for (int i = 0; i < size; i++) {
JSONObject another_json_object = the_json_array.getJSONObject(i);           
    System.out.println((String) another_json_object.get("productname"));        
    System.out.println((String) another_json_object.get("imageurl"));       
    System.out.println((String) another_json_object.get("producturl"));
}

Android provides the org.json package that can be used to parse your String to a JSONObject.

You can achieve this with this line of code:

JSONObject json = new JSONObject(myJsonString);

You've to use the JSONObject for this. Use of below code -

JSONParser .java

public JSONObject getJSONFromUrl(String url)  // url is your json url
{

    // Making HTTP request
    try {
        // defaultHttpClient
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();           

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    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();
        json = sb.toString();
    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    // try parse the string to a JSON object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }

    // return JSON String
    return jObj;

}

it will return the JsonObject And, using this jsonbobject we can get the result as array.

// Creating JSON Parser instance
JSONParser jParser = new JSONParser();

// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url);

try {
    // Getting Array of Contacts
    contacts = json.getJSONArray(TAG_CONTACTS);

    for(int i = 0; i < contacts.length(); i++) {

        String product_name = contacts.getString("productname");
        String image_url = contacts.getString("imageurl");
        .....
        .....
        String store_name = contacts.getString("storename");
    }
}catch(JSONException e) 
{
    e.printStackTrace();
}

There is a working example YatayatService that uses json library and custom JsonParser.java using apache http library. The implementation method is getAllRoutes().

String jsonString = JsonParser.parseJSON(URL);
try {
    JSONObject parentObject = new JSONObject(jsonString);
 } catch (JSONException e) {
    e.printStackTrace();
 }

Try This code

 // getting JSON string from URL
    JSONObject json = jParser.getJSONFromUrl(url);

    System.out.println("json is "+json);
    System.out.println("Length"+json.length());

    for (int i = 0; i < json.length(); i++) {
        try {
            String atObj = Integer.toString(i);
            System.out.println(atObj);
            JSONObject jObj = json.getJSONObject(atObj);
            System.out.println(jObj.getString("productname"));
            System.out.println(jObj.getString("imageurl"));
            System.out.println(jObj.getString("producturl"));
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
