Answer 1

Just Log it

String response = getData();

Log.d("Response", response);

try {
    JSONObject json = new JSONObject(response);
} catch (JsonException e) {

}

Though, if you know it is HTML, why are you trying to parse JSON?

Fix the server to always return JSON even in the case of errors before you try to do anything client-side.

^{Additionally, Eclipse has long been deprecated for Android (going on 2 years)}

Answer 2

ON the backend, the POST data is inserted into sql. I believe there is an SQL error that's being returned hence the

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("barcode", sv.getBarcode()));
params.add(new BasicNameValuePair("scannerid", sv.getScanner()));
params.add(new BasicNameValuePair("loccode", sv.getLoccode()));
params.add(new BasicNameValuePair("longitude", sv.getLong()));
params.add(new BasicNameValuePair("latitude", sv.getLat()));
params.add(new BasicNameValuePair("svtime", sv.getSVTIME()));

JSONObject json = jParser.makeHttpRequest(url_create_svruns,
        "POST", params);

Log.d("Create Response", json.toString());

// check for success tag
try {
    int success = json.getInt(TAG_SUCCESS);
