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?

I found the answer to this question elsewhere, I think it was only a minor thing as it worked after changing only a few things which stopped the response from being null as the request was sent successfully.
