ReferenceError: Can't find variable: $, jquerymobile + phonegap - android

I'm a newbie. I want to save a value inputted by the user in the preferences manager, and have it automatically populate a field(if it has been filled by the user). I get a "ReferenceError: Can't find variable: $ at file:///android_asset/www/index.html:53" in my Android logcat. Also my app crashes. What am I doing wrong?

If '$' isn't defined I don't think that jQuery is being loaded correctly..
Try:
if ( $.mobile ) {
// loaded
} else {
// not loaded
}
to check if jQuery mobile is loaded, or try this for normal jQuery:
if (!jQuery) {
alert("jQuery is not loaded");
}

You need to include jQuery in your page in order to use $ (jQuery) which you did not. You can add the script tag and give the url of jquery in src attribute. Add this tag in head tag so that it is added before it is required.
<script src="http://code.jquery.com/jquery-latest.min.js"
type="text/javascript"></script>

I think you forgot to update your access policy to allow all urls, update your config.xml file with the following code:
<access origin="*" />

Remote image serving to phonegap app

In a nutshell, I've built an app using HTML/CSS/JS and Phonegap. It's still in testing phase. I have all my app's images saved in Google Cloud Storage (GCS). I have image tags (divs) within my app that needs to pull those images from GCS to the specific div. However, this method of just adding the direct URL only seems to work on iOS devices. What I need to know is, what is the correct method of pulling those images from GCS to my app so that it works on all platforms (iOS, Android, BlackBerry etc)? Do I need to add a line of code in the head of my index.html or does it have something to do with the config.xml? I've been looking for answers on the net, but nothing could give me clear-cut results that works across all platforms.
I'm still fairly new to the whole "app building game", please be gentle.
Here is some code:

Javascripts wont execute in Android webview

i have created a web app using query mobile and html5 and currently, none of my JS executes in the application.
JS is enabled on Android WebView as Jquery mobile can execute the JS for the library but does not work on an android device.
It works fine on the iOS simulator and on the web browser so i am wondering if there is some kind of hidden settings/implementation i need to handle for android?
here is the error i receive from an onClick event on a simple dialog html that is outputted using phone gap
07-15 09:25:00.621: E/Web Console(2992): Uncaught ReferenceError: uploadTrue is not defined at file:///android_asset/www/itemDetailCarHire.html:2
Here is the itemDetailCarHire html that launches the dialog that executes the onClick.

When a user clicks the Original receipt component, it will correctly display the dialog called uploadRecieptDialog.html and the code for that is below:

</html>
Here is the updateDetailCarHire.JS
function uploadTrue(){
alert("upload true");
//load previous page
history.back(-1); return false;
alert("UPLOADED");
}
A simple JS as you can see that displays an alert message and goes back to previous screen. on iOS simulator and chrome/safari desktop web browser, it works!
I'm guessing your Javascript isn't executing because cordova is having a problem with your history command.
Check here: in Cordova 1.8.1 - Android history.back() not working
And possibly: Why is javascript:history.go(-1); not working on mobile devices?
Try using history.back();
EDIT: I don't see updateDetailCarHire.JS being included on any of those HTML pages.

PhoneGap, jQueryMobile pageinit on first page does not fire

I am using jQueryMobile and PhoneGap to develop a cross platform mobile app. I am binding to the first page that is loaded in the app (the 'home' page) but the pageinit event does not fire. Here's my custom javascript:
$('#home').live('pageinit', function()
{
alert('firing pageinit');
}
Here's my index.html file with the page definition:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="format-detection" content="telephone=no" />
<meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height" />
<link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css" />
<link rel="stylesheet" href="css/custom.css" />
</head>
<body>
<div data-role="page" id="home">
<div data-role="header" data-position="fixed">
Refresh
<h1>MyListingsApp</h1>
Add
</div>
<div data-role="content">
<ul data-role="listview" id="listings" data-filter="true" data-filter-placeholder="Filter listings...">
<li id="hit_to_begin"></li>
</ul>
</div>
</div>
<script type="text/javascript" src="cordova-2.2.0.js"></script>
<script src="js/jquery-1.8.2.min.js"></script>
<script src="js/jquery.mobile-1.2.0.min.js"></script>
<script src="js/jquery.ui.map.full.min.js"></script>
<script src="js/jquery.ui.map.services.min.js"></script>
<script src="js/jquery.i18n.min.js"></script>
<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript">
app.initialize();
</script>
<script type="text/javascript" src="js/custom.js"></script>
</body>
The event does not fire and all I get is the loaded homepage. According to the jQueryMobile docs this is proper binding to handle customization on page initialization.
Look at this example: http://jsfiddle.net/Gajotres/BGkaq/, I made you 2 examples, you can find them at the bottom of the page.
Event binding example 1:
// in (url^=home) home is a page id
$(':jqmData(url^=home)').live('pagebeforecreate',function (event) {
alert('Event has been triggered!');
});
Event binding example 2:
$('#home').live('pagebeforecreate',function (event) {
alert('Event has been triggered!');
});

how to change page in multipage hybrid app file using $.mobile.changePage()?

in my hybrid app, i'm trying to change page in a multipage file using jquery mobile function changePage.
when i press the button it hides current pages and shows blank page. same if i'm hidding/showing divs using hide/show jquery functions.
it works perfect in pc web browsers. but in mobile app.
how can i change/show second page?
here is my code:
<head>
<meta name="viewport"
content="width=device-width, initial-scale=1, maximum-scale=1">
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<script src="js/jqtouch/jqtouch.js" type="application/x-javascript"

<link type="text/css" rel="stylesheet" media="screen"
href="js/jquery.mobile-1.1.0.min.css">
<link type="text/css" rel="stylesheet" media="screen"
href="js/jquery.mobile.theme-1.1.0.min.css">
<link type="text/css" rel="stylesheet" media="screen"

<script type="text/javascript" charset="utf-8" src="js/wormhole.js"></script>
<script type="text/javascript" charset="utf-8"
src="js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" charset="utf-8"
src="js/jquery.mobile-1.1.1.js"></script>
</head>
<body>
<div id="TaskList" data-role="page">
<div data-role="header">
<h1>Dienos užduotys</h1>
</div>
<script type="text/javascript">
function showTaskDetails(id) {
$.mobile.changePage("#taskDetails", {
transition : "slideup"
});
}
</script>
<div data-role="content">
<div id="task_list" data-role="controlgroup">
<a data-role="button" onclick="showTaskDetails(1)" href="#">Name</a>
</div>
</div>
</div>
<div id="TaskDetails" data-role="page">
<div data-role="header">
<a href="#TaskList" data-icon="arrow-l" data-iconpos="left"
data-rel="back">Atgal</a>
<h1>Dienos užduotys</h1>
</div>
<div data-role="content">
<input type="text" value="" id="task_id" />
</div>
<div data-role="footer"></div>
</div>
</body>
UPDATE: seems like the problem appeared because of changePage function that is in login file.
If you have multiple pages of documents, only need to do this:
$.mobile.changePage("#taskDetails", {transition : "slideup"});
$.mobile.changePage("file1.html", {transition : "slideup"});
$.mobile.changePage("file2.html", {transition : "slideup"});
......
