Why Mobile? 4 Billion devices worldwide

iPhone • 50 Million iPhones - 5 Million this past quarter • 1.5 Billions application downloads • 65K+ applications • iPhone has raised bar and proven how to make money in mobile

Android • 1M phones already shipping (900% growth expected) • 20 new phones coming out EY 2009 • Thousands and thousands of applications • It’s Google

iPhone: 8% market share but 43% of mobile web

Explosion of opportunities 20% year over year growth anticipated for next 5 years in smart phones

Oh no. • iPhone (Objective-C, 28th!) • Android (Java, Google Style) • RIM (Java, Blackberry or Midlet style) • Symbian (old school C) • Palm Pre (Web 2.0) • Windows Mobile (.NET compact) • Maemo (GTK+)

Oh, yeah... • Web Browsers • Desktop Apps • Net books • E-Book readers • Tablets • etc etc.

We Web • HTML, CSS, JavaScript • Presentation / UI can easily be built with HTML/ CSS • JavaScript API for mobile features, platform, UI • Run locally, integrate cloud services

It’s the UX Build applications that ﬁt the use cases that are tailored for the modality

What we want • Skills • Tools • Reusability • Platforms • Portability • Speed / Cost • Open source / Standards

Titanium • Desktop: Win32, OSX, Linux • Mobile: iPhone and Android

Programming Model Titanium supports JavaScript, HTML, CSS for building mobile applications

UI • Clean separation of Design from Code • UI is constructed via HTML, CSS • JavaScript access to create native controls, native views, windows, etc.

JavaScript • JavaScript is used to program Mobile Features, Access local Resources, Database, Remote Web Services, etc. • Use your favorite JS Toolkit - jQuery,YUI, Dojo, Mootools, etc etc.

App Assembly Titanium SDK compiles (using Titanium Developer) the application using the Mobile SDK into a native application

Mobile APIs Geolocation Accelerometer Gesture Analytics Media App Network Database Platform Filesystem UI

Building the UI • <html> accepted here (including HTML5) • optimized native UI controls • hybrid UI composition

Typical iPhone UI

Typical Android UI

<html>

Native UI views Grouped View Table View

Composite UI

Simple APIs Titanium.UI.setTabBadge(10) Titanium.UI.createMenu()

Grouped View Example var groupedView = Titanium.UI.iPhone.createGroupedView(); groupedView.addSection(optionSection); groupedView.addSection(buttonSection); groupedView.addSection(inputSection); groupedView.open({animated:true});

Button Group Section var optionData = [ {title:'Option 1', selected:true}, {title:'Option 2'}, {title:'Option 3'} ]; var optionSection = Titanium.UI.iPhone.createGroupedSection({header:'Option Group', type:'option', data:optionData}); optionSection.addEventListener('click',function(e) { });

Input Group Section var inputData = [ {title:'Input 1', input:switchInstance, image:'iTunes.png'}, {title:'Sound', input:sliderInstance, image:'Mail.png'}, {title:'Name', input:textInstance}, {title:'Input 2', value:'foo', hasChild:true}, {title:'Input 3'} ]; var inputSection = Titanium.UI.iPhone.createGroupedSection({header:'Input Group', type:'input', data:inputData}); inputSection.addEventListener('click',function(e) { });

Native UI Controls • Toolbars • Tab Bars • Status Bars • Dialogs • Controls

Native UI (Android)

Databases var db = Titanium.Database.open('mydb'); db.execute('INSERT INTO DATABASETEST (ID, NAME ) VALUES(?,?)', 1,'Name 1'); db.execute('INSERT INTO DATABASETEST (ID, NAME ) VALUES(?,?)', 2,'Name 2'); db.execute('INSERT INTO DATABASETEST (ID, NAME ) VALUES(?,?)', 3,'Name 3'); db.execute('INSERT INTO DATABASETEST (ID, NAME ) VALUES(?,?)', 4,'Name 4');

Camera Titanium.Media.showCamera( { success:function(image,details) { $("status").innerHTML="Uploading...."+image.url; } });

Video var video = Titanium.Media. createVideoPlayer({ contentURL : "movie.mp4"}); var listenerId = video.addEventListener("complete", function() { video.removeEventListener('complete', listenerId); var dlg = Titanium.UI.createAlertDialog({ 'title' : 'Video Complete', 'message' : 'video completed', 'buttonNames' : [ 'OK' ] }); dlg.show(); }); video.play();

Gestures function onShake() { document.getElementById("status").innerHTML = 'Stop Shaking me'; } var listenerId = Titanium.Gesture.addEventListener("shake", onShake);

Accelerometer Titanium.Accelerometer.addEventListener('update',function(e){ document.getElementById('x').innerHTML = e.x; document.getElementById('y').innerHTML = e.y; document.getElementById('z').innerHTML = e.z });
