showDialog(DIALOG_LOADING);
}
protected String doInBackground(String... args) {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("customer_id",
Constants.response));
json = jParser.makeHttpRequest(url_all_products, "GET", params);
Log.d("All Products: ", json.toString());
try {
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
products = json.getJSONArray(TAG_PRODUCTS);
for (int i = 0; i < products.length(); i++) {
JSONObject c = products.getJSONObject(i);
String customer_id = c.getString(TAG_PID);
String product_id = c.getString(TAG_ID);
HashMap<String, String> map = new HashMap<String,
