I have a problem with AJax/Json petitions with PhoneGap. I have this code:

I have added in config.xml (/res/xml/) my domain ("http://www.cinesimf.com/*") in the phonegap whitelist.
If I try the code in a navigator in my pc, it works OK, but in Android aplication nevers load.
Your problem depends on a general webkit (and modern browsers) issue.
If you want to do a json request to a cross-domain server you have to modify your manifest file on Android or your plist file non Iphone, inserting the allowed domains where you want to get your data.
You could also do a jsonp request to avoid manifests updates:
$.getJSON("http://www.cinesimf.com/rss/JSONTorrevieja.php?callback=?",
function(data){
for (i=0;i<data.length;i++)
{
$("#ulCartelera").append('<li><a href="app.html" data-transition="slide" text="hola" >'+data[i].titulo+'</a></li>');
}
$('#cargaDiv').html(''); //Remove Loading message
$("#ulCartelera").listview('refresh');
})
You can have a good explanation about jsonp there: http://www.ibm.com/developerworks/library/wa-aj-jsonp1/

I'm a veteran programmer but am new to the whole mobile phone app programming and have just delved into PhoneGap. I have a pretty simple page I've put together using JQuery Mobile, PhoneGap, and Jquery but I've run into a snag. When I click on the href to load the "news" page, the .ajax() method doesn't seem to execute. I've got it in the traditional document ready wrapper and removing that doesn't seem to help the issue like I thought. So maybe I'm all screwed up but I cannot figure out why it wont fire UNLESS you refresh the page, then it works fine. Might be an newbie question but I feel like I am first year programmer.
Update: To be clear about what my issue is, I am testing in Firefox and have the PhoneGap desktop app serving the code. When I click on the News button the page loads but the elements that are added by Ajax don't appear. If I hit refresh on the browser, the page reloads and the elements appear. They never show up on the mobile phone unless I make a change to the code which forces the phonegap desktop app to cause the page to reload on the phone. So it's always the reload which causes it to happen.
Here is my code:

Can someone tell me why the ajax wont execute unless I refresh the page first? Thanks in advance.
I finally figured it out. The news.html page shouldn't have had the html, head section, or body tags.... just simply the contents of the body. After getting rid of that jQuery mobile loaded the new page into the "template" that was already there.
I did go ahead and replace the jquery's document onready event with:
document.addEventListener("deviceready", function(){
so now my new news.html page looks like this:
<div id="home" data-role="page">
<script type="text/javascript">
document.addEventListener("deviceready", function(){
var output = $('#news');
$.ajax({
url: 'http://xxxxxx.com/api/news/getnews',
dataType: 'jsonp',
cache : false,
jsonp: 'jsoncallback',
timeout: 5000,
success: function(data, status){
$.each(data, function(i,item){
var story = '<div data-role="collapsible"><h1>'+item.title+'</h1>'
+ '<p>'+item.body+'<br><small>'
+ item.date+'</small></p></div>';
output.append(story).enhanceWithin();
});
},
error: function(){
output.text('There was an error loading the data.');
}
});
});
</script>
<div data-role="header" data-position="fixed">
<h1>News</h1>
</div>
<div role="main" class="ui-content" id="news">
<div data-role="collapsible">
<h1>Hi</h1>
<p>Am I collapsible?</p>
</div>
</div>
<div data-role="footer" data-position="fixed">
<h4>Footer content</h4>
</div>
</div>
That's the content of the entire page. I will say that after I fixed this I began getting errors with my Content-Security-Policy and that's a whole other question but it seems to be working now and loading the ajax like it is supposed to.
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.

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.

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.
I am using cordova for mobile app development on android platform.
I have this html code in www/index.html file:

I don't know why but when I am running this app (also when just opening on pc browser) i am having this div appended at the bottom of the page:
<div ui-loader ui-corner-all ui-body-a ui-loader-default>
<span ui-loader ui-corner-all ui-body-a ui-loader-default></span>
<h1>loading</h1>
Here is the content of main.js:
$(document).ready(function(){
$('#box').click(function(){
if($(this).attr('class') == 'bodyBlack'){
$(this).removeClass('bodyBlack');
$(this).addClass('bodyWhite');
}
else{
$(this).removeClass('bodyWhite');
$(this).addClass('bodyBlack');
}
});
});
Why and from where dose it getting from? how I am preventing it to do so?
Thanks!!!
This seems to be a "Loading Message" generated by jQuery Mobile, see this answer. So jQuery Mobile is loading something (and cant't find it, perhaps). Please post the content of your main.js file if you're still having trouble!

This code is working fine for Android. but in iOS,as soon as the page loads then the pageinit event of page1 doesnt get fired and later on if i changepage to page2 then everything is fine.. Why is this happening?
am not so sure about that but as i know live function has changed in JQ1.7.x and now you will have to use the on() function which has small changes to the way you code your code ..
I just need to write my javaScript functions after data-role="page" to make it working...
