There is no JSONArray

 JSONObject jsonObject = new JSONObject(response);
      String name = jsonObject.getString("status");
                        String name1 = name.trim();
     if (name1.equals("success")) {

                            Toast.makeText(getApplicationContext(),"inside",Toast.LENGTH_LONG).show();
                            try {
                                   JSONObject  jsonObjectData = jsonObject .getJSONObject(i);
                                    s_key = jsonObjectData.getString("initKey");
                                    s_iv = jsonObjectData.getString("initIv");
                                    sec_url = jsonObjectData.getString("url");
                                    s_init_hash = jsonObjectData.getString("initHash");
                                }
                            } catch (JSONException e) {
                                e.printStackTrace();


            }

change this `JSONObject jsonObjectData = jsonObject .getJSONObject(i);` — AskNilesh, Apr 24 '18 at 07:26

You Response is JSONObject not in JSONArray check it

FYI

{ } brackets means JSONObject

[ ] brackets means JSONArray

Parse your json like this

    JSONObject jsonObject = new JSONObject(response);
    String name = jsonObject.getString("status");
    String name1 = name.trim();
    if (name1.equals("success")) {

        Toast.makeText(getApplicationContext(), "inside", Toast.LENGTH_LONG).show();
        try {


            JSONObject jsonObjectData = jsonObject.getJSONObject("data");
            s_key = data.getString("initKey");
            s_iv = data.getString("initIv");
            sec_url = data.getString("url");
            s_init_hash = data.getString("initHash");


        } catch (JSONException e) {
            e.printStackTrace();


        }


    }

thankyou for your time ,, small mistake in your answer : JSONObject jsonObjectData = jsonObject.getJSONObject("data"); — , Apr 24 '18 at 07:23

data Is not Json Array cause it start with {} it`s Json Object

Json Array start with []

So you need To use

SONObject  jsonObjectData = jsonObject .getJSONObject(i);

When you are working with JSON data in Android, you would use JSONArray to parse JSON which starts with the array brackets. Arrays in JSON are used to organize a collection of related items (Which could be JSON objects). For example:

[{"name":"item 1"},{"name": "item2} ]

On the other hand, you would use JSONObject when dealing with JSON that begins with curly braces. A JSON object is typically used to contain key/value pairs related to one item. For example:

{"name": "item1", "description":"a JSON object"}

 JSONObject jsonObject = new JSONObject(response);
  String name = jsonObject.getString("status");
                    String name1 = name.trim();
 if (name1.equals("success")) {

                        Toast.makeText(getApplicationContext(),"inside",Toast.LENGTH_LONG).show();
                        try {
                              JSONObject data = jsonObject. getJSONObject("data");
        s_key = data.getString("initKey");
        s_iv = data.getString("initIv");
        sec_url = data.getString("url");
        s_init_hash = data.getString("initHash");
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();


        }
