Hello,

I am developing an app with Kendo Mobile js library and AppBuilder Windows Client.

My problem is in my application when I press Back button on FirstPage it raises an exception instead of quitting app "Uncaught ReferenceError: start is not defined" , I am sharing my example code, I am trying it with Andy (emulator), Samsung Note 3 (Android 4.3 ) and Genymotion (Android 4.4.4), and behaves same on each environment.

I can not find how to archive my project in appbuilder.

Kendo UI Core v2015.2.813

index.html

<!DOCTYPE html>

<html>

<head>

<title></title>

<meta charset="utf-8" />

<link href="kendo/styles/kendo.mobile.all.min.css" rel="stylesheet" />

<script src="cordova.js"></script>

<script src="kendo/js/jquery.min.js"></script>

<script src="kendo/js/kendo.mobile.min.js"></script>

<script src="app.js"></script>

</head>

<body>

<div data-role="layout" data-id="main" >

<div data-role="header">

<div data-role="navbar">

<span data-role="view-title"></span>

<button data-role="backbutton" data-align="left" data-click-on="down" >Back</button>

</div>

</div>

</body>

</html>

main.html

<div data-role="view" data-title="Main Page" data-layout="main" data-transition="overlay" >

First Page

<button data-role="button" onclick="app.mobileApp.navigate('second.html');">Second Page</button>

</div>

app .js

var app = {

data:{}

};

document.addEventListener('deviceready', function () {

// hide the splash screen as soon as the app is ready. otherwise

// Cordova will wait 5 very long seconds to do it for you.

navigator.splashscreen.hide();

app.mobileApp = new kendo.mobile.Application(document.body, {

// comment out the following line to get a UI which matches the look

// and feel of the operating system

skin: 'flat',

// the application needs to know which view to load first

initial: 'main.html',

transition:'slide'

});

window.onerror = function(msg, url, line, col, error) {

// Note that col & error are new to the HTML 5 spec and may not be

// supported in every browser. It worked for me in Chrome.

var extra = !col ? '' : '\ncolumn: ' + col;

extra += !error ? '' : '\nerror: ' + error;

// You can view the information in an alert to see things working like this:

alert("Error: " + msg + "\nurl: " + url + "\nline: " + line + extra);

// TODO: Report this error via ajax so you can keep track

// of what pages have JS issues

var suppressErrorAlert = true;

// If you return true, then error alerts (like in older versions of

// Internet Explorer) will be suppressed.

return suppressErrorAlert;

};

second.html

<div data-role="view" data-title="Second Page" data-layout="main" data-transition="overlay" >

Welcome to second Page!

</div>

Hi Yilmaz,

You can exit the application invoking navigator.app.exitApp().
For example:

<button data-role="button" data-align="left" onclick="navigator.app.exitApp()">Back 1</button>

You can also write a more complicated logic in a function to serve the requirement you have.
index.html:

<button data-role="button" data-align="left" onclick="onButtonDown()">Back 2</button>

app.js:

// Handle the button

function onButtonDown() {

// Exit the app!

alert("Exited!");

navigator.app.exitApp();

}

As a side note, in regard to archiving a solution, please check the topic on Export Your Project.
I hope this helps.
