org.json.JSONException: No value for senses

org.json.JSONException: No value for senses - java

I am trying to make an English Dictionary using the Oxford API. I made this according to docs and resources found on the web. But I got this issue "org.json.JSONException: No value for senses" and I don't why. Wherever I looked I couldn't find reason of this issue. I'll give you my MainActivity and request class. Can anyone help me?
MainActiviy:

textView = findViewById(R.id.textView);
editText = findViewById(R.id.editText);
url = dictionaryEntries();
}

MyDictionaryRequest myDictionaryRequest = new MyDictionaryRequest(this);
myDictionaryRequest.execute(url);

try to validate the "senses" with senses.has("senses") before use it and then parse it with optjsonarray or optjsonobject for this type and check this key or check at backend side from where what value getting in json response.

Modify a variable from a class within a class

This is what I essentially want to do, but can't. I want the value of urlData and size to be updated from the inner class functions. The app is crashing by giving a Null Pointer Exception at the line where I try to access these variables from the CreateTextView() function.

The inner class is not static, so it needs an instance of the enclosing class to be instantiated. Like so:
public class abcd {
static int x;
public static void main(String[] args) {
abcd o = new abcd(); // Create instance of abcd called 'o'
abcd.efgh o2 = o.new efgh(); // Use instance 'o' to create an instance of efgh
System.out.println(x); // 0
o2.ok();
System.out.println(x); // 5
}
class efgh {
public void ok() {
x = 5;
}
}
}

}
And the PROBLEM IS IN MainActivity.java

See http://developer.android.com/intl/es/reference/android/os/AsyncTask.html. Especially the part with the result.
onPostExecute(Result), invoked on the UI thread after the background computation finishes. The result of the background computation is passed to this step as a parameter.

Finally I solved by using volley library thanks for the response.

Java and Listview: JSON value changes color display

below is my mainactivity java code

how to build up a string url by using method in android dynamically?

I have made one activity. In that I have to use one asynctask for api. So in that asynctask my url will be dynamically generated based on some number. I have tried as below, but it's not the proper way. Can anybody show me how I can make this url?
my sample url is:http://yehki.epagestore.in/app_api/order.php?customer_id=41&address_id=31&products[0][productName]=rt&products[0][product_id]=41&products[0][quantity]=2&products[0][unit]=1&products[0][unitPrice]=400&products[1][productName]=rt&products[1][product_id]=40&products[1][quantity]=2&products[1][unit]=1&products[1][unitPrice]=400

Make sure if you use a builder helper class like that you initialize it before the loop.
That said, UriBuilder is a perfect solution for your problem, it's a helper class for building or manipulating url's.
Below is an example for you:
Uri.Builder builder = new Uri.Builder();
builder.scheme("http")
.authority("yehki.epagestore.in")
.appendPath("app_api")
.appendPath("order.php")
.appendQueryParameter("customer_id", customer_id)
.appendQueryParameter("address_id", address_id);
for (int i = 0; i < carts.length(); i++) {
builder.appendQueryParameter("products["+i+"][productName]", cartList.get(i).get((Const.TAG_PRODUCT_NAME)));
builder.appendQueryParameter("products["+i+"][productId]", cartList.get(i).get((Const.TAG_PRODUCT_ID)));
builder.appendQueryParameter("products["+i+"][quantity]", cartList.get(i).get((Const.TAG_QUANTITY)));
builder.appendQueryParameter("products["+i+"][unit]", cartList.get(i).get((Const.TAG_UNIT)));
builder.appendQueryParameter("products["+i+"][unitPrice]", cartList.get(i).get((Const.TAG_RETAIL_PRICE)));
}
String myUrl = builder.build().toString();

You can use Spring Android Rest Template
http://projects.spring.io/spring-android/
You can create a class with your request representation and if it is a post request you can send it as below.
/* user Registration screen */
public UserAccount registerUser(UserAccount user) {
final String url = Util.BASE_URL + "/user/register";
RestTemplate restTemplate = new RestTemplate();
restTemplate
.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
restTemplate.getMessageConverters().add(
new MappingJackson2HttpMessageConverter());
ResponseEntity<UserAccount> responseEntity = restTemplate.exchange(url,
HttpMethod.POST, new HttpEntity<UserAccount>(user,
jsonReqAndResHeaders()), UserAccount.class);
return responseEntity.getBody();
}
The above shown is the code we use to register a User. Created a UserAccount class populated it with data and sent it to the server using a POST request.
This is similar to your scenario, you can create an Order class populate all the data and just hit the server url as shown above.
If you should use a GET request and prepare a URL, but for long urls like yours its always best to go with POST.
Hope this helps. Thanks

How do I pass parameter to webservice and get json datas in listview

Hi (fresher to andorid)
I'm developing an android application which will use the webservice which should accept 1 parameter from the user and based on that the value is fetched datas from DB(sql server 2008) and bind that to android:LISTVIEW.
Without using the parameter my android application is working fine.But when i altered my webserservice to accept parameter and call it in android it is not displaying the result based on the given value instead of that it displays all values.
Here is my webservice code;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.Script.Serialization;
using System.Web.Script.Services;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.ComponentModel;
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
// [System.Web.Script.Services.ScriptService]
public class JService : System.Web.Services.WebService
{
public JService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public void Cargonet(string jobno)
{
try
{
System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NSConstr"].ToString());
SqlCommand cmd = new SqlCommand();
//cmd.CommandText = "SELECT id,name,salary,country,city FROM EMaster where age = '" + jobno + "'";
cmd.CommandText = "SELECT [Id] as Id,[Status] as status ,[DateTime] as DateTime FROM [Attendance].[dbo].[cargo] WHERE JobNo= '" + jobno + "' ";
DataSet ds = new DataSet();
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.SelectCommand.Connection = con;
da.Fill(dt);
con.Close();
List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
Dictionary<string, object> row = null;
foreach (DataRow rs in dt.Rows)
{
row = new Dictionary<string, object>();
foreach (DataColumn col in dt.Columns)
{
row.Add(col.ColumnName, rs[col].ToString().Trim());
}
rows.Add(row);
}
this.Context.Response.ContentType = "application/json; charset=utf-8";
this.Context.Response.Write(serializer.Serialize(new { Cargo = rows }));
}
catch (Exception ex)

org.json.JSONException: No value for senses - java

try to validate the "senses" with senses.has("senses") before use it and then parse it with optjsonarray or optjsonobject for this type and check this key or check at backend side from where what value getting in json response.
