I am getting HTTP response string like below. I want subject_id and status string from response string

Response string is like this:

{
  "images": [
    {
      "transaction": {
        "status": "success",
        "topLeftX": 325,
        "topLeftY": 451,
        "gallery_name": "Ironman",
        "subject_id": "Tony",
        "confidence": 0.99414,
        "height": 630,
        "width": 630,
        "face_id": 1,
        "quality": 1.75477
      },
      "candidates": [
        {
          "subject_id": "Tony",
          "confidence": 0.99414,
          "enrollment_timestamp": "1487644861022"
        },
        {
          "subject_id": "Tony",
          "confidence": 0.99414,
          "enrollment_timestamp": "1487644876280"
        }
      ]
    }
  ]
}

I tried this code but not working.. 

JSONArray arr = new JSONArray(response); 
JSONObject jObj = arr.getJSONObject(0); 
String status = jObj.getString("status"); 
String message = jObj.getString("subject_id");

You tried 

JSONArray arr = new JSONArray(response);

but you should

JSONObject arr = new JSONObject(response);

Because your main json is json object, not JSONArray

You can use GSON to parse JSON Strings. If you just want the first object of the images array you can use this code:

JsonParser jsonParser = new JsonParser();
JsonObject obj = jsonParser.parse(responseString).getAsJsonObject();
JsonArray images = obj.getAsJsonArray("images");
String subjectId = images.get(0).getAsJsonObject().get("transaction")
    .getAsJsonObject().get("subject_id").getAsString();

use this

   @Override
    protected void onPostExecute(String result) {
        JSONObject jsonobj;
        // TODO Auto-generated method stub
        super.onPostExecute(result);


        if (result != null) {
            if (result.equals("failure")) {
                Toast.makeText(context, "Check your Username or Password", Toast.LENGTH_LONG).show();
                dialog.dismiss();

            } else {//ths is getting data for vehicl_list_unread_count code, client id,restapi_key
                try {
                    Log.d(TAG, "onPostExecute: this inner of post" + getcontent_for_validate);
                    jsonobj = new JSONObject(getcontent_for_validate);
                    System.out.println("this is get content" + jsonobj.toString()); JSONArray array = jsonobj.getJSONArray("images");for (int i = 0; i < array.length(); i++) {
                       JSONArray transaction = array.getJSONObject(i).getJSONArray("transaction");for (int i = 0; i < array.length(); i++)
                        String status = transaction.getJSONObject(i).getString("status");
                        Password = editText_password.getText().toString();
                    }


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


            }


        } else {
            dialog.dismiss();
            Toast.makeText(context, "Check net connection", Toast.LENGTH_LONG).show();
        }

    }

Use json simple lib

JSONObject json = new JSONObject(yourString);
JSONArray images = json.getJSONArray("images");

and you can loop throw this array

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