Hello Swati:

Hi all,

I'm developing a mobile app that need to consume ajax/json web services.

The application works fine when I test in Intel XDK enviroment and in Intel App Preview android app, but when I build the application an install it in the device and error ocurr. I test in Galaxy S2 (Android 4.1.2) and the response status was 0 and S5 (Android 5.0) and the response was 404 (not found).

I don't know if this affects, but recently the IntelXDK enviroment updated to version 1878 (I think but not sure that before the update I can consume cross domain webservices, is it possible?).

I search for the solution several days and test different codes but the error persist. Finally I create a basic application from XDK to try solve the problem but with no result. This is my test code (extract from the Intel XDK article https://software.intel.com/en-us/xdk/docs/how-to-access-JSON-data-in-HTML5-apps):

<!DOCTYPE html>
<html>
<head>
    <title>Blank Cordova App Project Template</title>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8">
    <script src="intelxdk.js"></script>
    <script src="xhr.js"></script>       
    <script src="cordova.js" id="xdkJScordova_"></script>
    <script src="js/app.js"></script>           <!-- for your event code, see README and file comments for details -->
    <script src="js/init-app.js"></script>      <!-- for your init code, see README and file comments for details -->
    <script src="xdk/init-dev.js"></script>     <!-- normalizes device and document ready events, see file for details -->    
    <script src="scripts/jquery.min.js"></script>     
    
    <script>
        function transferFailed(e) {
            alert("Error:"+e.target.status);
        }
        function callJsonWS(){           
            $.getJSON("http://time.jsontest.com", function(data){
                alert(data);
            });       
        }
    </script>
</head>

<body onload="callJsonWS()">
    <h1 class="align-center">A Blank Project Template</h1>
</body>    
</html>

The result of the code below is no response when I install the app in the Android device.

Sorry for my english and thank you in advance.

Hello Miguel,

Please send your whole project in a zip file and also .apk separately. You can PM me your app.

Hello Swati: First of all thank you for your response. I have sent you a message with the files you request. Best regards, Miguel Angel

Hi Miguel,

The project you sent me doesn't work, neither on emulator nor App Preview. Please find this attached sample ajax code and see if it works for you.

Thanks,

Swati

Hi Swati,

I test my code again and it works on the emulator. I have tested in XDK 1878 and Motorola Droid as emulator. The application only makes a call on body load and show and alert.

The good news are that your sample code works for me in emulator and in the device too :-). Now I'm going to compare the apps to discover why mine doens't work. When I'll do I'll write again in this thread with the conclusion.

Thans a lot,

Miguel Ángel

Hi Miguel,

The issue with starting your project from scratch from the template in XDK 1878 is that Domain List is left blank in the project build settings. Please put * in the domain list and your ajax call will work in your app.

This issue is being fixed and will be available soon.

Hi Swati,

The issue you comment was the problem.

I added <access origin="*"/> to my intelxdk.config.android.xml file and all works fine, in my test app and in my original app.

Thank you very much for your help, I was a little desperate.

Best regards,

Miguel Ángel
