Question

I am trying to invoke webservice using jquery ajax call.
I am using jasonp as a datatype to fix cross domain issues.

It works fine in all browsers. i tested it on other domains. i am getting a valid responce.
When i try to run it from android device emulator webservice call fails.

Please suggest.

Code :

function getJsonData()
{
    alert("Within get json function.. ");
    (function($) {
    var url = 'http://localhost:8080/mobile-services/rest/languages.json?callback=callback';
    $.ajax({
       type: 'GET',
        url: url,
        async: false,
        contentType: "application/json",
        dataType: 'jsonp'
    });
})(jQuery);
}
function callback(data)
        {
            alert(data);
        }

webservice response.

callback([{"language":"English","id":1},{"language":"Hindi","id":2},{"language":"Marathi","id":3}])

which is a valid jsonp response.

In web service URL try using 10.0.2.2 instead of localhost.
localhost or 127.0.0.1 points to emulator / android device while 10.0.2.2 is a special alias to your host loopback interface (i.e. 127.0.0.1 on your development machine). Check this Link for more details.
