I have a RESTful API running in my local machine which returns a response in JSON (Actually this JSON is the response of nodejs Soap client request) depending on the request. For this particular case I receive POST request from an Android client and return the following response:

{
    QueryAcctBalResponse: {
        BalExDtoList: {
            BalExDto: [{
                BalID: "xxxx",
                AcctResID: "xxxx",
                AcctResName: "xxxx",
                BalType: "xxxx",
                Balance: "xxxx",
                EffDate: "xxxx",
                ExpDate: "xxxx",
                UpdateDate: "xxxx"
            }, {
                BalID: "yyyy",
                AcctResID: "yyyy",
                AcctResName: "yyyy",
                BalType: "yyyy",
                Balance: "yyyy",
                EffDate: "yyyy",
                ExpDate: "yyyy",
                UpdateDate: "yyyy"
            }]
        }
    }
}

The problem is each time I try to parse that response and display this information in android (Particularly "AcctResName"). I get org.json.JSONException: No value for BalExDto. I use Volley Libray in android to parse Json and i used Jsonobject request.

Request Code.

JsonObjectRequest sq = new JsonObjectRequest(Request.Method.POST, balanceUrl, request, new Response.Listener<JSONObject>() {

    @Override
    public void onResponse(JSONObject response) {

        try {
            JSONArray jsonArray = response.getJSONArray("BalExDto");
            for (int i = 0; i < jsonArray.length(); i++){
                JSONObject jsonObject=jsonArray.getJSONObject(i);
                Toast.makeText(CheckBalance.this, ""+jsonObject.get("AcctResName"), Toast.LENGTH_LONG).show();
            }

            pd.hide();
        } catch (JSONException e) {
            e.printStackTrace();
        }
        Log.d("Response", "Response_TAG: "+response);

    }

The error says - you are parsing BalExDto wrong. BalExDto is not direct child of response. So you have to parse QueryAcctBalResponse and BalExDtoList and then you can get BalExDto. Because BalExDto is inside BalExDtoList and BalExDtoList is inside QueryAcctBalResponse.

JsonObjectRequest sq = new JsonObjectRequest(Request.Method.POST, balanceUrl, request, new Response.Listener<JSONObject>() {

@Override
public void onResponse(JSONObject response) {

    try {
        JSONObject queryAcctBalResponse = response.getJSONObject("QueryAcctBalResponse");
        JSONObject balExDtoList = queryAcctBalResponse.getJSONObject("BalExDtoList");
        JSONArray jsonArray = balExDtoList.getJSONArray("BalExDto");
        for (int i = 0; i < jsonArray.length(); i++){
            JSONObject jsonObject=jsonArray.getJSONObject(i);
            Toast.makeText(CheckBalance.this, ""+jsonObject.get("AcctResName"), Toast.LENGTH_LONG).show();
        }

        pd.hide();
    } catch (JSONException e) {
        e.printStackTrace();
    }
    Log.d("Response", "Response_TAG: "+response);

}

Solved: Volley returns null error after hitting an endpoint that sends , I get org.json.JSONException: No value for BalExDto. I use Volley Libray in android to parse Json and i used Jsonobject request. Request Code. And now you have an object representing the response! Notice how I made the field names of the "Song" object have the same names as the values you care about (in this case it appears network and site is what you wanted). Gson does the job of serializing a JSON object to a POJO that you can directly access values cleanly, and easier.

It's because you don't have a JSON Array, you have a JSON Object.

First of all, you need to get the JSON object from your API response,

JSONObject jsonObject = response.getJSONObject("QueryAcctBalResponse")

and inside that JSON object is the JSON Array.

JSONArray jsonArray = response.getJSONArray("BalExDtoList");

Make a standard request, It's very possible for a request to reach the server but the reply not to get back to the device. In this case, by trying only once, you'll not only surface� Reference Learning JSON Data in Android. If your JSON data start with Object node ( { ) then use below Request JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, JSON_URL, null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) {

BalExDto array is not the direct child of the response. It is inside BalExDtoList which is inside QueryAcctBalResponseobject. You can not directly access any node in the JSON, you need to traverse the full path before you could access them.

You need to get the array like below

JSONObject queryAcctBalResponse = response.getJSONObject("QueryAcctBalResponse");
JSONObject balExDtoList = queryAcctBalResponse.getJSONObject("BalExDtoList");
JSONArray jsonArray = balExDtoList.getJSONArray("BalExDto");

JSONObject, Specify a URL and receive a raw string in response. See Setting Up Volley provides the following classes for JSON requests: GET, url, null, JsonParse.Java Trying to get the json array object from URL but it is throwing Parsing ERROR and CountriedBean is my POJO class. parse_json just has ListView and

Networking for Android made easy: The Volley Library, When the requested type is a String, other non-null values will be Returns the value mapped by name if it exists and is a JSONObject This value violates the general contract of Object#equals by returning true when compared to null . JSONException, if the parse fails or doesn't yield a JSONObject . 3-JSONObject jsonValue – this is your JSON data which will be used when you send the post request. 4- VolleyCallback callback – This is your interface object. and in onResponse(String Response) you can pass the Response value to the interface function onSuccessResponse(Response). Like

com.android.volley.toolbox Class JsonObjectRequest, Below is the code for a JSON api call using HttpURLConnection approach. toString()); } finally { if(connection != null) connection.disconnect(); } return null; } printStackTrace(); return Response.error(new VolleyError("Error parsing network� For example, we are using a requests library to send a RESTful GET call to a server, and in return, we are getting a response in the JSON format, let’s see how to parse this JSON data in Python. We will parse JSON response into Python Dictionary so you can access JSON data using key-value pairs. Also, you can prettyPrint JSON in the readable

Volley, A request for retrieving a JSONObject response body at a given URL, allowing for Constructor which defaults to GET if jsonRequest is null , POST otherwise. this to parse the raw network response and return an appropriate response type. This post is about Android Volley Tutorial. And here we will do a straightforward thing. I have a URL that gives me some JSON data, and by using Volley I will get that data, and I will also parse it. So if you want to learn how do we fetch and parse JSON from a URL in android then let’s start this Android Volley Tutorial.
