deviceready won't fire in Phonegap 1.0.0 on Android - android

I've tried to setup Phonegap on Android and deviceready won't fire. The reason is that DeviceInfo.uuid is always null/undefined.
It seems like the non-javascript parts of phonegap isn't loaded correctly, but I can't see exactly what. For everything outside the www directory I'm using the code provided in the sample directory of the phonegap download.
Anyone know what may be causing this?
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no;" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<script type="text/javascript" charset="utf-8" src="javascripts/phonegap-1.0.0.js"></script>
<script src="http://debug.phonegap.com/target/target-script-min.js#something"></script>
<script type="text/javascript" charset="utf-8">
function onBodyLoad() {
var initialize = function() {
window.console.log("deviceready||resume");
};
document.addEventListener("deviceready", initialize);
document.addEventListener("resume", initialize);
window.console.log("onBodyLoad!");
}
</script>
</head>
<body onload="onBodyLoad()">
<h1>Herro World</h1>
</body>
</html>

In case someone else stumble on this problem.
I hadn't realized that phonegap-1.0.0.js is different for the iPhone and Android version. It has the same name, but the content is different. Thus, one must load the correct file. I solved it like this:
<script type="text/javascript">
// Atrocious way of loading two diffent phonegap scripts, but other loading methods won't work.
// also there shouldn't be two scripts to begin with -- so much for cross-platform.
var userAgent = navigator.userAgent.toLowerCase();
if (userAgent.match(/android/)) {
document.write("<script type='text/javascript' src='javascripts\/phonegap-android-1.0.0.js'><\/script>");
} else {
document.write("<script type='text/javascript' src='javascripts\/phonegap-iphone-1.0.0.js'><\/script>");
}
</script>

If you want some function to execute when the device is ready do something like this
document.addEventListener("deviceready", onDeviceReady, true);
// PhoneGap is now ready
function onDeviceReady() {
// Write your code here
}
I am not sure why your code is not working.Try placing the document.addEventListener outside the scope of the function.

Getting the device language for a Phonegap application

I'm developing an html5/JqueryMobile/Phonegap app. I have to detect the device language to redirect to a specific html. I'm trying to use Phonegap's navigator.globalization.getPreferredLanguage. On an iOS device it works fine.
The code below detects the language "onDeviceReady" and performs the redirect. This code should be universal for iOS and Android but when I try it on an Android device it doesn't work. The screen freezes. What might cause this?
<!DOCTYPE HTML>
<html>
<head>
<title>Language</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
navigator.globalization.getPreferredLanguage(
function (language)
{
if(language.value == "it")
{window.location.replace("index_it.html");}
else if (language.value == "ar")
{window.location.replace("index_ar.html");}
else
{window.location.replace("index_en.html");}},
function ()
{
alert('Error getting language\n');
}
);
}
</script>
</head>
<body>
</body>
</html>
Problem here, is that language received from Android will have different format, for example instead of Russian with code ru it will return русский

onDeviceReady function not called

I'm working my way through my first phonegap tutorial but I'm having problems.
I've set that the onDeviceReady() function be called when the "deviceready" event is fired, but the method is never called.
I tried calling the App.start() method directly, but I get an error in the console that the APP.start() method doesn't exist.
Thanks for your help!

UPDATE:
Changed type="application/javascript" to `type="text/javascript"'
add deviceready listener in load listener.
Still no luck!
Replace your tags with:
<script type="text/javascript" ...
using a application/javascript mime type isn't the standard approach.
Check your code for syntax errors (run it in Safari, or Chrome etc with the console open to see them). I find that when things don't work in PhoneGap it's usually because a JS error has crept in somewhere.
Remove all the scripts except the thing you're trying to test (lines to set the deviceready event, and the function it runs), then introduce each block of code and script one-by-one to see when it stops. That way you can isolate the block of code that is causing the problem.
I have experienced a similar problem myself. I will try to offer whatever advice I can.
First up, If you look at the Phonegaps Device Ready documentation, it notes that Typically, you will want to attach an event listener with document.addEventListener once the HTML document's DOM has loaded.. The reason for this, if you look at the source code, is that they're actually overriding document.addEventListener with their own function which handles all bindings of deviceready.
I found myself that when I was loading phonegap dynamically, if I would add my event listener for devicereadybefore it had hooked in, it would never come, but if I waited until the script element was loaded, it worked fine. Usually if you're just working with <script> tags directly, they actually load synchronously, so this isn't an issue. It's possible that having the scripts in the body element might cause them to load in a non-synchronous fashion, so I'd probably try moving them to the head or just above the </html>, and try changing to a more standard script element, like Henry suggests.
<script type="text/javascript" src="cordova/cordova-2.2.0-android.js"></script>
<script type="text/javascript" src="framework/utility.js"></script>
<script type="text/javascript" src="app.js"></script>
Your js should be like this
document.addEventListener("deviceready",onDeviceReady,false);
function onDeviceReady() {
alert("WOAH!");
start();
}
function start() {
PKUTIL.include([ "framework/ui-core.js", "framework/device.js" ],
function() {
init();
});
}
When your js is load, and cordova ready, your function onDeviceReady will be executed. This function will do an alert and then call the function start.
Try to change
$$(document).on('deviceready', function() {
// Your content here
});
For
$$(document).on('DOMContentLoaded', function(){
// Your content here
});

angular ng-view phonegap is not working

I am trying to make basic app with angularjs and phonegap in android. But it doesn't seem to be working. Below are my source code files:
index.html
<!DOCTYPE html>
<html ng-app="main-app">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript">
app.initialize();
</script>
</body>
</html>
main.js
var mobileApp = angular.module("main-app", []);
mobileApp.config(function ($routeProvider,$compileProvider) {
$routeProvider
.when("/",
{
templateUrl: "partial/home.html",
controller: "homeController"
})
.when("/home",
{
templateUrl: "partial/home.html",
controller: "homeController"
});
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel):/);
});
mobileApp.controller("MainCtrl",function($scope){
alert('Coming here');
$scope.isViewLoading=true;
});
mobileApp.controller("homeController",function($scope){
alert('Home Coming here');
});
index.js
var app = {
initialize: function() {
this.bind();
},
bind: function() {
document.addEventListener('deviceready', this.deviceready, false);
},
deviceready: function() {
// note that this is an event handler so the scope is that of the event
// so we need to call app.report(), and not this.report()
app.report('deviceready');
angular.bootstrap(document, ['main-app']);
},
report: function(id) {
console.log("report:" + id);
}
};
When the app is getting load, router doesn't seem to work as its not getting into Homecontroller.
From what I have ready everywhere else, this code should work. Any help would be greatly appreciated.
I had the same problem, which I just found a solution to. Take a look at Angular ng-view/routing not working in PhoneGap
Move app.initialize(); to PhoneGap's deviceready event
I had this problem - I was stuck on it for 3 evenings - eventually I compared the template names in the routing to the actual file names - make sure the case matches.

PhoneGap Android jQuery Mobile app runs on device without CSS/JS

I've got a Phonegap (Cordova 2.0.0) app, built for Android, running with jQuery Mobile + Backbone.js. When I test it on the emulator, it works correctly (runs as in the browser, CSS and JS appear, etc).
When I sign it and install it on a non-debug device, it runs but without the CSS and JS (so basically shows an unstyled HTML document which doesn't run the JS).
The body of my app is as follows:
<!DOCTYPE html>
<html>
<head>
<title>My App</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no;" />

/**

function onBodyLoad()

// get device
$.os = {};
$.os.android = navigator.platform.indexOf("android")>=0;
$.os.ios = navigator.platform.indexOf("iPhone")>=0 || navigator.platform.indexOf("iPad")>=0;
// listen to device ready
if ($.os.android || $.os.ios) {
document.addEventListener("deviceready", deviceReady.resolve, false);
}
else {
// must be in a browser, so immediately resolve
deviceReady.resolve();
}
}
$(document).bind("mobileinit", jqmReady.resolve);
$(document).bind("mobileinit", function() { console.log('mobileinit'); });
$(document).bind('pageinit', function() { console.log('pageinit'); });
// when jquery mobile and device ready, then fire
$.when(jqmReady, deviceReady).then(function() {
console.log('Ready');
// disable push state: http://jquerymobile.com/demos/1.1.1/docs/pages/page-links.html
$.mobile.pushStateEnabled = false;
App.init();
});
onBodyLoad();
</script>
</head>
<body onload="" data-lat="" data-lng="">
Has anyone come across this before? I was wondering if it's something to do with the relative paths (rather than absolute?) or how I package it together in Eclipse. Also, on an iPhone it works fine.
Thanks.

Html 5 Android PhoneGap

I am developing an android application. In that, I am trying to get the image in the javascript, but its not loading. Can someone help me to get the image in the javascript in the phone gap android app...
Code:
<img src="img/nextIcon.png" /></span>'
why the end span tag ?
Basically your file should look something like this:
<!DOCTYPE HTML>
<html>
<head>
<title>Something</title>
<script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script>
<script type="text/javascript" charset="utf-8">
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
}
</script>
</head>
<body onload="onLoad()">
<img src="img/nextIcon.png" />
</body>
</html>
And then of course you should have included the image in a folder called img which is in you www folder
