The Json you posted does not contain any array. Its a JSON object. A Json array starts with [. You can read more about JSON from here.

Now, regarding parsing:

Do it as follows:

    try {

        JSONObject jsonObject = json.getJSONObject("data");

        String pNumber = jsonObject.getString("PNumber");
    } catch (JSONException e) {
        e.printStackTrace();
    }
