Titanium not recognizing its own API for android

I have a window that's part of a tab group. When I try to set the right nav button, I get the following runtime error:
Uncaught TypeError: Object #Window has no method setRightNavButton
However, the method is clearly listed in the API for Titanium.UI.Window. Interestingly enough, it doesn't have a problem with the setLeftNavButton method which is executed just before. Also, it executes perfectly running on ios, but has issues when running on android. Any help would be greatly appreciated.
Here's the code to create the window in question:
var queryWindow = Titanium.UI.createWindow({
barColor : '#1ADC2FF',
layout : 'vertical',
backgroundColor : '#1389d1',
title : L('Search'),
fullscreen : true
});
var clearButton = Ti.UI.createButton({
title : L('Clear'),
style : Titanium.UI.iPhone.SystemButtonStyle.BORDERED,
right : 10,
width : 60,
font : {
fontSize : 14
},
color : '#2952CC',
height : 30
});
....<MORE UI INITIALIZATION>....
queryWindow.setLeftNavButton(findButton);
queryWindow.setRightNavButton(clearButton); //Error thrown here
queryWindow.add(queryTable);
queryWindow.add(queryView);
return queryTab;

The method setRightNavButton and setLeftNavButton is only for iOS, that's why it throw an error on Android : http://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.Window-method-setRightNavButton

Ionic - disable animation for nav bar

My app has a static header. Meaning it remains the same in all views.
The problem is that when I use the <ion-nav-bar> directive the header is animated every time the view changes.
On IOS it's not that bad because the entire is sliding in, but on Android it looks like it flickers.
How can I disable the animation entirely?
I already tried using $ionicConfigProvider.navBar.transition('none'); in the app.config section, but it actually made it worse (also flickers on IOS).
I created a simple codepen (the default transition appears to that of IOS, but if you open the developer console on chrome and change to an android device you can see the flickering).

if you really no idea to how solve this.
you can modify the transition function
First, in app.config section
$ionicConfigProvider.navBar.transition('android');
then, modify ionic transition function
$ionicConfigProvider.transitions.navBar.android = function(enteringHeaderBar, leavingHeaderBar, direction, shouldAnimate) {
function setStyles(ctrl, opacity) {
if (!ctrl) return;
var css = {};
// ionic original
// css.opacity = opacity === 1 ? '' : opacity;
// modify
if (opacity === 1) {
css.opacity = '';
css.display = '';
} else {
css.opacity = opacity;
css.display = 'none'; // let leavingHeaderBar immediately disappear
}
ctrl.setCss('buttons-left', css);
ctrl.setCss('buttons-right', css);
ctrl.setCss('back-button', css);
ctrl.setCss('back-text', css);
ctrl.setCss('title', css);
}
return {
run: function(step) {
setStyles(enteringHeaderBar.controller(), step);
setStyles(leavingHeaderBar && leavingHeaderBar.controller(), 1 - step);
},
shouldAnimate: shouldAnimate && (direction == 'forward' || direction == 'back')
};
};

If you are using Ionic 2 or higher, use the following CSS only:
.toolbar{
.title, button{
opacity: 1!important;
transform: none!important;
}
}

jQuery Dropdown Menu with Android

I wrote this script for a navigation menu on the phone. If an item has drop downs, it prevents the link, then displays the drpdown.
$(document).ready(function() {
var bodyWidth = window.screen.availWidth;
if(bodyWidth <= 600) {
$('ul.dropdowns li > a').click(function(event) {
var parent = $(this).closest('li');
var nester = $(this).closest('li').closest('ul').closest('li');
var type = parent.attr("class");
if(parent.hasClass('dropdown') || parent.hasClass('flyout')) {
event.preventDefault();
$(parent).siblings().attr("id", "");
var isActive = (parent.attr("id") == "active" ? true : false);
(isActive ? $(parent).attr("id", "") : $(parent).attr("id", "active"));
}
});
};
});
This works fine with the iPhone, but on Android it gets screwed. I'm at a total loss, any ideas?
By, "gets screwed" I mean nothing happens on Android when you try to click a link.

I found the problem. I was using a CSS transition that for some reason Android wasn't keeping up with.

Disable animation on image recognition with Wikitude SDK 3.0

I'm integrating a modified SDK 3.0 sample into a big app in which I'm working.
When I detect whatever Trackable2DObject and show an ImageDrawable (for example, the surf table), this ImageDrawable appears from the z-index very slowly.
Is there any way to disable this animation?
Thanks in advance!
EDIT: My JS code only contains this:
var World = {
loaded: false,
init: function initFn() {
this.createOverlays();
},
createOverlays: function createOverlaysFn() {
// Initialize Tracker
this.tracker = new AR.Tracker("assets/wul4bus.wtc", {
onLoaded: this.worldLoaded
});
// Create overlay for page one
var imgOne = new AR.ImageResource("assets/redsys_marker_orange.png");
var overlayOne = new AR.ImageDrawable(imgOne, 0.5, {
zorder: 0,
offsetX: -0.15,
offsetY: 0,
onClick: this.createClickTrigger
});
var titleLabel = new AR.Label("Bus", 0.07, {
zOrder: 1,
offsetX: -0.15,
offsetY: 0.04,
style: {
textColor: '#FFFFFF',
fontStyle: AR.CONST.FONT_STYLE.BOLD
}
});
var pageOne = new AR.Trackable2DObject(this.tracker, "002", {
drawables: {
cam: [overlayOne, titleLabel]
}
});
},
createClickTrigger: function createClickTriggerFn() {
document.location = "architectsdk://product?id=1236";
},
worldLoaded: function worldLoadedFn() {
document.body.removeChild(document.getElementById('loadingMessage'));
}
};
World.init();
As you see, there is no AR.PropertyAnimation class along this code. Anyway, a small animation succedeed sometimes when the target is discovered, and trackable object appears a bit slowly, slower than SDK 2 IMHO. It happens with some Trackable2DObject more than others.

Please have a look at the API Reference of the Wikitude SDK.
You will find details around Animations there.
If you need a Sample collection and platform specific stuff, have a look at the Wikitude Documentation page.
Kind regards,
Andreas

Titanium: navigation from one screen to other

On the click of my button, I want to navigate to another screen. How would I achieve this in Titanium?
var TrialButton = Titanium.UI.createButton({
color:'black',
backgroundColor:'#FFFFFF',
title:'Trial Mode',
top:55,
width:300,
height:50,
borderRadius:5,
font:{fontSize:18, fontFamily :'Helvetica', fontWeight:'bold'}
});
TrialButton.addEventListener('click', function() {
var newWindow = Titanium.UI.createWindow({
background : "#fff",
title : "Trial Demo",
url:"nextScreen.js"
});
newWindow.open();
});

TrialButton.addEventListener('click', function()
{
var newWindow = Ti.UI.createWindow({
background : "#000",
title : "Image View",
url:"nextScreen.js"
});
newWindow.open();
)};
should checkout examples here https://github.com/appcelerator/KitchenSink
here are some posts from my blog http://blog.clearlyinnovative.com/tagged/Appcelerator

If you're using Alloy, You can also navigate to another screen using the Alloy.createController method.
function sample(e) {
var nextScreen = Alloy.createController('nameOfNextScreen').getView();
nextScreen.open();
}
If you wish, you can also pass data to the next screen by passing it in as an argument eg,
var nextScreen = Alloy.createController('nameOfNextScreen', {sushi: "california roll" }).getView();
and retrieving the argument in the next screen with the following
var args = $.args;
var value = args.sushi;

TrialButton.addEventListener('click', function()
{
var newWindow = Ti.UI.createWindow({
background : "#000",
title : "Image View",
url:"nextScreen.js"
});
newWindow.open();
//close your current window of this page and also in your nextScreen.js page, the window must be set to current window
)};

Because its written wrong. Theres an error in code at the last line. The ")" has to follow after "}". Not opposite ast written here. So the closing tag is right like this: "});". Use following code instead:
TrialButton.addEventListener('click', function()
{
var newWindow = Ti.UI.createWindow({
background : "#000",
title : "Image View",
url:"nextScreen.js"
});
newWindow.open();
//close your current window of this page and also in your nextScreen.js page, the window must be set to current window
});
