I'm trying to send a request to the Google-Shopping API with the following static method which I think is working:

public static String GET_TITLE(String url) throws JSONException {

    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());
    }

The URL I'm passing is this BTW: https://www.googleapis.com/shopping/search/v1/public/products/country=US&q=shirts&alt=json &rankBy=relevancy&key=AIzaSyDRKgGmJrdG6pV6DIg2m-nmIbXydxvpjww

Next I try to parse this response (where I think the problem comes in) in the same method:

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

    JSONObject itemObject = jArray.getJSONObject("items");
    JSONObject productObject = itemObject.getJSONObject("product");

    String attributeGoogleId = productObject.getString("googleId");
    String attributeProviderId = productObject.getString("providerId");
    String attributeTitle = productObject.getString("title");*/
    String attributePrice = productObject.getString("price");
    JSONObject popupObject = productObject.getJSONObject("popup");

        return attributeTitle;
    }

This has been so frustrating, I know it should be simple but everywhere I look I just can't quite get it to work, I'm not exactly sure what the error is since I'm testing it on my HTC Desire because my emulator gives an 'invalid command-line parameter' error when starting, but that's a different issue, anyway, thanks in advance!

EDIT:

The first one makes it look like there's a problem with the URL, should I change it and see if it makes a difference?
