InAppBrowser not closing?

I'm using the InAppBrowser plugin (v1.1.1) with Cordova for an OAuth login process. Unfortunately, the InAppBrowser doesn't appear to be closing the browser. My "closeBrowser" function instead continually triggers the interval, and the browser remains on-screen on the Android (I have not tried other devices at this time.)
Is there a way to forcibly close the InAppBrowser other than .close(), or hide it? Or maybe there's a flaw in my code somewhere that is locking the browser.
LogInPage.prototype.handleExternalLogin = function (externalLogin) {
var _this = this;
var ref = window.open(Environment_1.settings.baseUrl + externalLogin.route.url, "_blank", "location=no");
ref.addEventListener('loadstart', function (event) {
if (_.startsWith(event.url, Environment_1.settings.baseUrl + "/api/Account/account/ExternalLoginCallback")) {
// Now we want to load a different url that will give us the mobile access token
console.log('get external-mobile-token');
_this.closeBrowser(ref);
var ref2 = window.open(Environment_1.settings.baseUrl + "/api/Account/external-mobile-token", "_blank" /*, "location=no"*/);
ref2.addEventListener('loadstop', function (event) {
console.log('loadstop ' + event.url);
if (event.url == Environment_1.settings.baseUrl + "/api/Account/external-mobile-token") {
ref2.executeScript({ code: 'window.document.documentElement.innerText' }, function (contents) {
_this.login(contents);
_this.closeBrowser(ref2);
});
}
});
ref2.addEventListener('loaderror', function (event) {
console.log(event);
_this.closeBrowser(ref2);
// TODO - do something?
});
}
});
ref.addEventListener('loaderror', function (event) {
console.log(event);
_this.closeBrowser(ref);
// TODO - do something?
});
};
LogInPage.prototype.closeBrowser = function (browser) {
var interval = setInterval(function () {
console.log('closing');
browser.close();
}, 10);
browser.addEventListener('exit', function () {
console.log('closed');
clearInterval(interval);
});
};
LogInPage.prototype.login = function (token) {
console.log(token);
};
The above code is actually generated from TypeScript, but I figured I wouldn't confuse the issue.

It appears that closing an InAppBrowser and opening another at the same time was causing the issue; rewriting the process to only need one window solved my issue.

How can I get device Locale or Language with PhoneGap Build?

I'm using Phonegap Build to develop an application for iOS and Android.
I'd like to determine the locale (e.g. 'en-US') for the device, though I'd settle for the current language setting, or even the app store my app was installed from (it's been a long day).
Following the instructions here for the Globalization plugin I think I have everything right, but nothing seems to work on either the iPhone 6 or Samsung Galaxy Nexus I'm using for testing.
The relevant part of my config.xml looks like this:
<gap:plugin name="org.apache.cordova.globalization" />
My function for getting locale from the plugin looks like this:
var getPhoneGapLocaleName = function() {
var loc = 'unknown';
if (navigator.globalization !== undefined) {
navigator.globalization.getLocaleName(
function (locale) {
if (locale !== undefined) {
loc = locale.value;
}
},
function () {
// nothing
}
);
}
return loc;
};
Note: on both devices navigator.globalization.getLocaleName is present and appears correct, evaluating to a function resembling what I'd expect based on the documentation.

The problem here was that the variable 'loc' was declared outside the scope of the success or failure callbacks, which of course happen after a few brief moments.
I fixed this by changing the function thus:
var refreshPhoneGapLocaleName = function() {
if (navigator.globalization !== undefined) {
navigator.globalization.getLocaleName(
function (locale) {
if (locale !== undefined) {
localStorage['pg.locale'] = locale.value;
}
},
function () {
// nothing
}
);
}
};
Now calling it in onDeviceReady in order to refresh the values when the app starts.
A few moments later (not immediately) the following function can be used to retrieve the locale value:
var getLocale = function() {
return localStorage['pg.locale']();
};
The greatest thing about StackOverflow is how often it helps one to resolve one's own silly mistakes. :)

Although previous answers are returning the desired result, and giving an option to retrieve the current phonegap locale name, they did not explain the topic starter why his function did not work, and how to adjust his function to work in the way he intended (i.e. not using localStorage and not showing the locale in the console but giving the answer in real-time as a result)
I am posting this answer since I was looking for a quick function to get the device locale, and this post was my first result. While the opening post gave me everything I needed, I would like to answer this question for future visitors with the same purpose I had. Sorry for posting to a topic this old, but I hope I can help others with my answer.
The reason the function of topic starter does not work is the following: the plugin returns the locale in an asynchronous way. Therefore, the loc =locale.value line is only executed after the function's return statement. To fix this, we can write a wrapper function to simplify the plugins output as follows. Keep in mind that we need to use this function asynchronously, since the plugin result is also asynchronous.
The function:
var getPhoneGapLocaleName = function ( callback ) {
var unknownLocation = 'unknown'; //Default value
if ( navigator.globalization !== undefined ) {
navigator.globalization.getLocaleName(
function ( locale ) {
if ( locale !== undefined ) {
callback( locale.value );
} else {
callback( unknownLocation );
}
},
function () {
callback( unknownLocation );
}
);
} else {
callback( unknownLocation );
}
};
Use the function like this:
getPhoneGapLocaleName( function( loc ){ console.log( 'The locale was set as follows: ' + loc ); } );

Try this code
When the browser is set to the en_US locale, this should display a popup dialog with the text language: English:
navigator.globalization.getPreferredLanguage(
function (language) {alert('language: ' + language.value + '\n');},
function () {alert('Error getting language\n');}
);

<html>
<head>
<title>getPreferredLanguage Example</title>

function (language) {alert('language: ' + language.value + '\n');},
function () {alert('Error getting language\n');}
);
}
</script>
</head>
<body>
<button onclick="checkLanguage()">Click for language</button>

Dynamic Image Loading in Android Offline HTML5 app using Sencha

Good day folks.
I am stuck with a strange problem and after lots of googling I couldn't find the solution/answer
I am creating and Sencha +cordova app for android.
It simply display 10 images in loop.
my code works fine on Chrome browser in desktop.
It fails On android 4.4.2 device when I install as APK.
Please help to fix the code for android.
init: function () {
this.callParent(arguments);
//console.log('init');
if(Ext.os.name == 'Android')
baseurl = baseAndroidUrl;
else
baseurl = baseDesktopUrl;
//alert('baseurl ' + baseurl);
}
var baseurl;
var baseAndroidUrl = 'file:///android_asset/www/resources/resources/images/';
var baseDesktopUrl = '/resources/resources/images/';
var imageArray =
['page00.jpg',
'page01.jpg',
'page02.jpg',
'page03.jpg',
'page04.jpg',
'page05.jpg',
'page06.jpg',
'page07.jpg',
'page08.jpg',
'page09.jpg',
'page10.jpg'];
var counter = 0;
-----------------------------------------------
onPrePageCommand: function () {
console.log('onPrePageCommand');
if( counter === 0 )
return ;
counter--;
// Folloing dynamic updation doesn't work in android , works perfectly on desktop
Ext.getCmp('pageID').setSrc(baseurl+imageArray[counter]);
//Ext.getCmp('pageID ').doLayout();
},
onNextPageCommand: function () {
console.log('onNextPageCommand');
if( counter === imageArray.length-1 )
return ;
counter++;
Ext.getCmp('pageID').setSrc(baseurl+imageArray[counter]);
},
------------------------------------------
//initial view : work perfect for both Desktop browser and APK
{
xtype: 'image',
src:'resources/images/Page00.jpg',
id:'pageID',
mode:'image'
height:'100%',
width:'100%'
}
--------------------------------------------

Try to use a Framework for that like http://wowslider.com/ this worked great for me the last time. You can also scroll the images with your fingers (swipe them).

Loading Spinner not showing while load a checkboxes

I am trying to show loading spinner while loading checkboxes using below code in jquery mobile 1.3.2 on Android native app, but it is not working, can any one help me what the issue is and how to make it work
Here is my code:
function onChangeCarrera(idCarrera,idEvento){
$.mobile.loading('show', {
text: 'Cargando Corredores',
textVisible: true,
theme: 'a',
html: ""});
cargaCorredores(idCarrera,idEvento);
resetMontoTotal();
$.mobile.loading('hide');
}
function cargaCorredores(idCarrera,idEvento){
var dom = jsel(json);
var carrera = dom.select('//Eventos/*[#id='+idEvento+']/carreras/*[#nroCarrera='+idCarrera+']');
//Muestra Label
$("#lblCorredores").text("Selección de corredores");
var html;
for (var x=1; x<=TipoApuesta.patas; x++){
html='<fieldset id="carrera"+x+"_fieldset" data-type="horizontal" data-role="controlgroup"><legend>'+eval("TipoApuesta.p"+x+"Nombre")+'</legend>';
$.each(carrera.corredores, function(i, corredor) {
html+='<input type="checkbox" onclick="resetMontoTotal();" value="'+corredor.nroCorredor+'" name="checkbox_'+idCarrera+'_'+idEvento+'_'+corredor.nroCorredor+'" id="checkbox_'+idCarrera+'_'+idEvento+'_'+corredor.nroCorredor+'" class="corredores'+x+'" /><label for="checkbox_'+idCarrera+'_'+idEvento+'_'+corredor.nroCorredor+'">'+corredor.nroCorredor+'</label>';
});
$("#carreras"+x).html(html+'</fieldset');
$("#carreras"+x).trigger("create");
}
if (TipoApuesta.patas<4){
for (var j=4; j>TipoApuesta.patas; j--){
$("#carreras"+j).html('');
$("#carreras"+j).trigger("create");
}
}
}
I'm using a json preloaded with the page to make a checkboxes.
Many thanks!

I read somewhere about needing to use interval variables. I had the same issue and this resolved it, although it's a little "hacky" to me.
var interval = setInterval(function () {
$.mobile.loading('show', {
text: 'Resuming...',
textVisible: true,
theme: 'a',
html: ""
});
clearInterval(interval);
}, 1);
I had to use a different variable name for interval on each of my app's pages.

PhoneGap App -- Drag and Drop in android as a via jquery mobile

Hi guys i am working on drag and drop event in android via jquery mobile. I tested the code on browser works fine but not on device. can anybody help me out this issue. I am following 1st tutorial of the link....
http://www.elated.com/articles/drag-and-drop-with-jquery-your-essential-guide/

The problem can be one of the followings:
1- the device has to have internet connection
2- the files you used are not "jquery mobile". they are just jquery files that are used to develop web pages.
3- If you use the application on a tablet, I guess your application can work by the mouse of tablet. However it can't work by touching.
These are the problems that I can guess. I hope you find the exact solution. And if you find it, please post it here for me :)

This is my script i have done Emrullah...
<script type="text/javascript">
$(document).ready(function() {
$( init );
function init() {
document.addEventListener("touchstart", touchHandler, true);
document.addEventListener("touchmove", touchHandler, true);
document.addEventListener("touchend", touchHandler, true);
document.addEventListener("touchcancel", touchHandler, true);
}
$(function(){
$(".drag")
.bind( "dragstart", function( event ){
// ref the "dragged" element, make a copy
var $drag = $( this ), $proxy = $drag.clone();
// modify the "dragged" source element
$drag.addClass("outline");
// insert and return the "proxy" element
return $proxy.appendTo( document.body ).addClass("ghost");
})
.bind( "drag", function( event ){
// update the "proxy" element position
$( event.dragProxy ).css({
left: event.offsetX,
top: event.offsetY
});
})
.bind( "dragend", function( event ){
// remove the "proxy" element
$( event.dragProxy ).fadeOut( "normal", function(){
$( this ).remove();
});
// if there is no drop AND the target was previously dropped
if ( !event.dropTarget && $(this).parent().is(".drop") ){
// output details of the action
$('#log').append('<div>Removed <b>'+ this.title +'</b> from <b>'+
this.parentNode.title +'</b></div>');
// put it in it's original <div>
$('#nodrop').append( this );
}
// restore to a normal state
$( this ).removeClass("outline");
});
$('.drop')
.bind( "dropstart", function( event ){
// don't drop in itself
if ( this == event.dragTarget.parentNode ) return false;
// activate the "drop" target element
$( this ).addClass("active");
})
.bind( "drop", function( event ){
// if there was a drop, move some data...
$( this ).append( event.dragTarget );
// output details of the action...
$('#log').append('<div>Dropped <b>'+ event.dragTarget.title +'</b> into <b>'+
this.title +'</b></div>');
})
.bind( "dropend", function( event ){
// deactivate the "drop" target element
$( this ).removeClass("active");
});
});
function touchHandler(event)
{
var touches = event.changedTouches,
first = touches[0],
type = "";
switch(event.type)

case "touchstart": type = "mousedown"; break;
case "touchmove": type="mousemove"; break;
case "touchend": type="mouseup"; break;
default: return;
}
var simulatedEvent = document.createEvent("MouseEvent");
simulatedEvent.initMouseEvent(type, true, true, window, 1,
first.screenX, first.screenY,
first.clientX, first.clientY, false,
false, false, false, 0/*left*/, null);
first.target.dispatchEvent(simulatedEvent);
event.preventDefault();
return;
}
});
</script>

Your code looks fine and you told that it had worked on browser successfully. I think the problem is possibly the jquery file that you used. If you had linked the jquery file that resides on a web site, make sure your device has internet connection. If no internet connection, download and put the "jquery mobile" file into the assest/www folder and link the file.
Didn't you run the application on an emulator? What is the error you faced?
