Is there a way using the Intel XDK library to determine if my app is running in the IDE's emulator vs. on an actual mobile device? I'd like to put in some logging and debugging code that is conditional on this information.
Thanks.
You can detect if you are testing/emulating your application in the XDK with the Intel XDK Javascript API. There is a property called isxdk which is a boolean value indicating if you are currently running in Intel XDK.
For example,
<!DOCTYPE html><!--HTML5 doctype-->
<html>
<head>
<title>Your New Application</title>
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0" />
<style type="text/css">
/* Prevent copy paste for all elements except text fields */
* { -webkit-user-select:none; -webkit-tap-highlight-color:rgba(255, 255, 255, 0); }
input, textarea { -webkit-user-select:text; }
body { background-color:white; color:black }
</style>
<script src='intelxdk.js'></script>
<script type="text/javascript">
/* Intel native bridge is available */
var onDeviceReady=function(){
//hide splash screen
intel.xdk.device.hideSplashScreen();
};
document.addEventListener("intel.xdk.device.ready",onDeviceReady,false);
</script>
<script>
if (intel.xdk.isxdk==true){
// Application is running in XDK
alert("Running in Intel XDK Emulator");
}
</script>
</head>
<body>
<h1>Welcome to Intel XDK</h1>
<p>Hello World</p>
</body>
</html>
For more information on the isxdk property, visit https://software.intel.com/en-us/node/493507.
Most methods of detection for this are more trouble than necessary. Have you tried logging to the javascript console? A line such as: console.log("X is" + x); to log a variable, or console.log(e); where e is an event can provide significant information when debugging (having the debug screen open in the emulator, or pulling up the javascript console when running in a browser) but remains invisible when on a mobile device.

I have this TWDC(tableau web data connector) app hosted on our company's private cloud.
Every app that are deployed there are accessed after the user logs in via a Single Sign On login page, then redirected to the app.
When I try to use my web data connector on my Tableau Desktop it gets stuck on an infinite loop, after i push the button which does tableau.submit().
I've set the debugger and found out, that when I push the button, the page that is loaded is not the index.html of my WDC but the redirect page from the SSO login.
I have no idea why is this happening, doesn't make much sense, because it loaded the index.html in the first place, but after i push this button it gets back to somewhere in the middle of SSO login and redirect page.
Just a note: It works fine on the simulator.
Any thougths on this?
Here's my code:
HTML
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>TableauAngular</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<script type="text/javascript" src="assets/js/jquery.min.js"></script>
<script type="text/javascript" src="assets/js/tableauwdc-2.3.latest.js"></script>
<script type="text/javascript" src="controller.js"></script>
</head>
<body>
<button id="submitButton">Send</button>
<br />
<br />
<textarea id="log" style="border: 1px solid #000; width: 100%; height: 700px;"></textarea>
<br />
<div id="placeholder"></div>
</body>
</html>
JavaScript
$(document).ready(function() {
try {
$("#submitButton").click(function() { tableau.submit() });
var myConnector = tableau.makeConnector();
// these are function which are not important for this question;
myConnector.getSchema = fnGetSchema;
myConnector.getData = fnGetData;
tableau.registerConnector(myConnector);
} catch (e) {
logger("ERROR: " + JSON.stringify(e));
}
});
This isn't a problem with your code. With the WDC there is an interactive phase where the user is shown a screen and can interact (this is your first SSO sign-in) but then there is a non-interactive (Get Data) phase where Tableau will try to retrieve the data and never shows the SSO login to the user. See docs. Given this page is loaded without user interaction it can't/shouldn't have SSO security on it.
I have saved the source of sample AMP video http://amp.azure.net/libs/amp/latest/samples/dynamic_setsource.html locally and trying to play video. It works in IE and Edge but not in chrome. if i host this file it works.
Can you please help me understand what is wrong here?
You can try running script in IE an Chrome to see the difference.

When you run the code locally, Chrome opens your index.html with the file:// protocol. Due to Chrome's security policy local resources aren't allowed to be loaded and that's what's preventing playback. (If you check out your JavaScript console, I bet you'll see a similar error.)
To workaround this, you can use an IDE like Visual Studio or WebMatrix that will automatically set up a local web server for you so you can access your page with http://localhost:8000 or whichever port you prefer.
If you don't want to use VS or WebMatrix, you could also use Python's Simple HTTP server. Hope this helps and happy coding :)
I want to convert my website to mobile application with Intel XDK. So , how to do this with web view.I want to load the URL on the current web view not open it on a new page with the native browser.
Easy way is to use window.location= to load URL:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, minimum-scale=1, initial-scale=1, user-scalable=no">
<script src="cordova.js"></script>
</head>
<body>
<script>
window.location = "http://www.yourwebsite.com";
</script>
</body>
</html>
Better way is to use InAppBrowser and connection Cordova plugins to load website, so that you can handle connection loss and reload, it will load complete website in background and then display, here is code: https://github.com/krisrak/html5-cordova-webapp
I can read english to some degree but I'm not good at writing.
Then I appologize for any rudeness.
I don't know well about wicket but I think it very good.
I want to deploy on wicket Javascript application made by LibGDX ,but on wicket's HTML file it does not work.
LibGDX logo was shown but next is not.(Maybe it seems to be not found next file (xxxx.cache.html) ??)
Please Tell me how to work Javascript(GWT) application on wicket.
Chrome shows this error.
Uncaught ED5709743BB488EF40123B0ADA51D171.cache.html:84393
com.badlogic.gdx.utils.GdxRuntimeException: Invalid assets description file.
My Javascript application is made by GWT which is client only created by LibGDX.
(LibGDX is multi platform game framework.
It can create WebGL application from java by GWT compiled.)
I think it can work in wicket because this GWT application is client only.
Javascript application is

I am developing Sencha touch application that will work on iPhone. Now application is ready and works fine in phone browser. But, now I want to distribute my application so I am using PhoneGap.
All my HTML and JavaScript pages are deployed at http://170.60.26.20:8099/Sencha/Html/index.html. Now i want to load that URL using phonegap. Suggest me the steps how could I do this.
I have installed phonegap-1.2.0-0 version.
Create new Phonegap App in xcode and you just need to modify already exist index.html file in www folder.
You can use window.location javascript method to load your web app in phone app.
In PhoneGap(Cordova).plist, add your server to the ExternalHosts list and make OpenAllWhitelistURLsInWebView to YES.
Please try following code to run your html pages in phonegap app.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<!-- Change this if you want to allow scaling -->
<meta name="viewport" content="width=default-width; user-scalable=no" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>LoadUrl
<!-- If you application is targeting iOS BEFORE 4.0 you MUST put json2.js from http://www.JSON.org/json2.js into your www directory and include it here -->
<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
function onBodyLoad()
{
document.addEventListener("deviceready",onDeviceReady,false);
}
/* When this function is called, PhoneGap has been initialized and is ready to roll */
function onDeviceReady()
{
// do your thing!
window.location="http://web.me.com/djpinter1/iPhone/jqtouch/demos/main_tabbar/#ui";
//window.location="http://170.60.26.20:8099/Sencha/Html/index.html";
}
</script>
</head>
<body onload="onBodyLoad()">
</body>
</html>
In your xcode , start a new project as phonegap project. Then copy the files from your project folder to www folder in the phonegap project.Keep in mind that index.html file should be in the parent folder , otherwise you have to change the url accordingly in the corresponding class that invokes a webview.
You can follow this link
http://wiki.phonegap.com/w/page/39991939/Getting%20Started%20with%20PhoneGap%20iOS%20using%20Xcode%204
Hope it will help
