AJAX POST not working in android studio webview

I have simple login page which uses AJAX POST the page works fine in the browsers. I have created an android studio project with the web view and given the link of the login page, I have also included HTML 5 features for the page, but the login page does not send or receive any data when i run it on the android studio emulator.
The AJAX POST CODE is as follows
var ins = empID + "~" + empPassword;
$.ajax({
type: "POST",
contentType: "application/json",
url: "http://Servername/Service1.svc/json/EmpLogin",
data: '{"EDetailslogin": "' + ins + '"}',
crossDomain: true,
dataType: "json",
processData: false,
success: function(data) {
widow.location.href = "Page2.html";
},
error: function(data) {
alert("User Not Recognized");
}
});
The android manifest code is as follows
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.Myproj.Sample">
<uses-permission android:name="android.permission.INTERNET" />

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
My Main Activity.java file has the following code with the HTML-5 features added to the page.
public class MainActivity extends AppCompatActivity {
private WebView wv1;
public String TAG;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

I have also Imported all the necessary class files. Still the application does not seem to work. Can anyone please help me with this.

How can I add form fields when I click on link only by using Struts2 without javascript/jquery

It's possible by using Struts2, jsp without javascript/jquery? if not how can I add jquery code in Struts2?

Implementing Ajax in spring MVC

Ajax is not sending the data to the specified URL. Here is my controller:
#Controller
public class HomeController {
private List<User> userList = new ArrayList<User>();
#RequestMapping(value = "AddUsers.htm", method = RequestMethod.GET)
public String showForm() {
return "AddUsers";
}
#RequestMapping(value = "User.htm", method = RequestMethod.POST)
public #ResponseBody
String addUser(#ModelAttribute(value = "user") User user,
BindingResult result) {
String returnText;
if (!result.hasErrors()) {
userList.add(user);
returnText = "User has been added to the list. Total number of users are"
+ userList.size();
} else {
returnText = "Sorry, an error has occur. User has not been added to list.";
}
return returnText;
}
#RequestMapping(value = "ShowUsers.htm")
public String showUsers(ModelMap model) {
model.addAttribute("Users", userList);
return "ShowUsers";
}
}
AddUser.jsp page
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%# page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<script src="/AjaxWithSpringMVC2Annotations/js/jquery.js"></script>
<script type="text/javascript">
function AjaxCall() {
alert('ready');
//get the form variables....
var name = $('#name').val();
var education = $('#education').val();
$.ajax({
type: "POST",
url: "AddUsers.htm",
data: " name=" + name + "&education=" + education,
success: function (response) {
$('#info').html(response);
$('#name').val('');
$('#education').val('');
},
error: function (e) {
alert('ERROR : ' + e);
}
});
}
</script>
<body>
<h1>Welcome to the AddUsers page. </h1>
<table>
<tr><td>Enter your name : </td><td> <input type = "text" id="name"></td></tr>
<tr><td>Educational qualification : </td><td> <input type = "text" id="education"></td></tr>
<tr><td colspan = "2"><input type="button" value="Add Users" onclick="AjaxCall()"></td></tr>
<tr><td colspan = "2"><div id ="info"></div></td></tr>
</table>
Show users
</body>
</html>
I have inserted an alert within the ajax which never comes up. So I believe there is something wrong with the ajax method.

I corrected the upper case problem ($.ajax instead of $.Ajax). Thanks for pointing out.
Now I have a different error:
POST http://localhost:8080/sum/AddUsers.htm 405 (Method Not Allowed)

change url:"AddUsers.htm" to url: "${pageContext. request. contextPath}/AddUsers.htm" and try.

the url you are calling is this
type: "POST",
url: "AddUsers.htm",
Which is POST, the controller method is GET. Hecne the 405 error, method not supported.

You try to send POST request but mapped your method call with GET method
#RequestMapping(value = "AddUsers.htm", method = RequestMethod.GET)
try to change RequestMethod.GET to POST

You seem to lack the ScriptService/ScriptMethod attributes on your service/service methods.

dojo web application requesting WCF service

I have setup a WCF service that returns json format data with my configuration file setup as follows:
<system.web>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webHttpBindingJsonP" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="webHttpBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="webHttpBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="webHttpBehavior" name="Services.Service1">
<endpoint address="mex"
binding="webHttpBinding" bindingConfiguration="webHttpBindingJsonP"
contract="Services.IService1" behaviorConfiguration="webHttpBehavior"/>
</service>
</services>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
My service WebInvoke function:
<OperationContract()>
<WebInvoke(Method:="GET", BodyStyle:=WebMessageBodyStyle.WrappedRequest, Responseformat:=WebMessageFormat.Json)>
Function RetrieveData(ByVal screenName As String) As Stream
And Finally my dojo based website's function to call the webservice:
<script type="text/javascript">
dojo.ready(function () {
dojo.io.script.get({ url:
"http://xxx.xxx.x.xxx/Services/Service/Service1.svc/GetData?item=Tweet",
callbackParamName: "callback",
content: { username: "me", password: "you" }
}).then(function (data){
return data.results;
})
});
</script>
The problem is that I cannot get the data to flow through to the dojo application. First I get the error callback undefined. Now I am not sure if I am clear on this callback thing: is it the name of the function in the dojo application as I have above but the function is not named or is it the name of the function the returns the json response in the web service which by the way is installed on a different domain.

this is what I do with .NET:
My service:
[OperationContract]
[WebGet(UriTemplate = "/GetMyStuff", ResponseFormat = WebMessageFormat.Json)]
public String GetMyStuff()
{
var myStuff = getFromService("foo");
return new { label = "name", identifier = "Id", items = myStuff.Select(w => new { Id = w.Id, name = w.Description }) }.ToJSON();
}
I use this ToJSON() helper function declared as this:
public static class LinqUtils
{
public static string ToJSON(this object obj)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(obj);
}
}
In web.config:
<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="false">
<serviceActivations>
<add relativeAddress="Services/StuffServiceJson.svc" service="MyStuff.MyStuffService" /> <!-- This is an actual URL mapping to your service endpoint -->
</serviceActivations>
</serviceHostingEnvironment>
<!-- other stuff -->
<services>
<service name="MyStuff.MyStuffService">
<endpoint binding="webHttpBinding" contract="MyStuff.MyStuffService" address="" behaviorConfiguration="webHttp"/> <!-- This is a service endpoint to your implementation class mapping -->
</service>
</services>
</system.serviceModel>
In Dojo:
require(["dojo/_base/xhr"], function(xhr) {
xhr.get({
url: "/Services/StuffServiceJson.svc/GetMyStuff",
handleAs: "json",
preventCache: true
}).then(function (data) {
//Do something with DATA
}, function (error) {
//Do something with error OMG
});
});
If you get a problem with the data being returned as string anyway (happens in .NET sometimes) then you're gonna have to take your data and do
require(["dojo/json"], function(json){
json.parse(data)
});
