You can try this

 try {
    JSONObject jsonObject = new JSONObject(response);
    JSONArray jsonArray = jsonObject.getJSONArray("result");

    for (int i = 0; i < jsonArray.length(); i++) {
    JSONObject jsonObject2 = jsonArray.getJSONObject(i);
    // do something
    Toast.makeText(context, jsonObject2.getString("active"), Toast.LENGTH_SHORT).show();
    }
} catch (JSONException e) {
                        e.printStackTrace();
                    }
