this is the API I am using digitalcodeeye.com/ethlon/api/get-parent-categories - Ahsan Mahmood
Please also post your code. Please see : Minimal, Complete, and Verifiable Example - Ankur Aggarwal
{ HttpHandler sh = new HttpHandler(); String url = SERVER_URL+get_parent_categories; jsonStr = sh.makeServiceCall(url); Log.e("TAG", "Response from url: " + jsonStr); return null;} protected void onPostExecute(Void result) { super.onPostExecute(result); if (jsonStr != null) { JSONArray contacts; try { contacts = new JSONArray(jsonStr); for (int i = 0; i < contacts.length(); i++) { JSONObject c = contacts.getJSONObject(Integer.parseInt(jsonStr)); String id = c.getString("id"); String image = c.getString("image"); String name = c.getString("name");} - Ahsan Mahmood

You are trying to convert an empty string ("") into a number. Add a check to the string before converting it to a number.

if(!string.isEmpty()) {
    Integer.parseInt(string);
}
