first your json String if it's contain "result" then it is not valid you can check it here http://jsonviewer.stack.hu/

to make valid json string just use String.replace as:

String finaljson=result.replace("result", "");

now JSON String is valid you can parse it as:

JSONArray jsonarray = new JSONArray(finaljson);
for (int i = 0 ; i < jarray.length() ; i++) {
 JSONObject jsonobj = jarray.getJSONObject(i);
  // get value from json object here 
    String str_City=jsonobj.getString("City");
    ///....
}

The Json array contains only one entry, the index is 0

JSONArray jarray = new JSONArray(result);
JSONObject jobj = jarray.getJSONObject(0);

To handle it right, access the json array using a for loop

JSONArray jarray = new JSONArray(result);
for (int i = 0 ; i < jarray.length() ; i++) {
     JSONObject jobj = jarray.getJSONObject(i);
     .....
}

Update your below code line it will solve your problem.

JSONObject jobj = jarray.getJSONObject(0);

or you can write below code instead of your above code line if object is more than one.

for(int i=0;i<jarray.length();i++){
    JSONObject jobj = jarray.getJSONObject(i);
}
