            } 
            catch (JSONException e) 
            {
                e.printStackTrace();
            }
            textViewResult.setText("CCRI Code:\t"+ccri+"Name:\t"+name+"\nAddress:\t" +address+ "\nTaluk:\t"+taluk+"\nPunchayat:\t"+punch);
        }

        @Override
        public void onClick(View v) {
            getData();
        }    
    }

In my code only ID is displaying... fetching is not performing.. Plz help!!

Answer 1

this is kinda complicated.

1. you'll have to check out if ur url is right. Print the url in console and type it in some browser do the GET request. If there's no response, well it might be your problem. Maybe you did not compose the url right.
2. if there's some response in step 1, ask the server guy what's going on there. and wait.
