Titanium enables web developers to create native mobile, desktop, and tablet applications using open web technologies (JavaScript, HTML, and CSS)

Titanium Key Facts
Open Source (Apache 2.0)
Pro Services, Training, Analytics and SLA Support available from Appcelerator
Mobile Platforms: iOS, Android, and BlackBerry (beta)
Desktop Platforms: Windows, OS X, and Linux

Titanium from 10,000 Feet
Mobile:
JavaScript APIs for UI (Native)
JavaScript for scripting
WebView available, but not required
Desktop:
HTML 5/ CSS 3 for UI (Webkit)
JavaScript, Ruby, PHP or Python for scripting

Native User Experience Native performance + Native UI (tables, animations, gestures…etc.) Multimedia Camera, video camera, streaming/device audio/video Location-based services Augmented reality, geo-location, compass, native maps Analytics Custom analytics baked into every application, track usage patterns and adoption Social sharing Authenticated access to Facebook, Twitter, Yahoo YQL. Native email/address book Titanium+Plus Encrypted database, ecommerce, ads, barcode scanners, custom analytics, in-app purchase Data Local SQLite data store, web services, lightweight key/value store Development tools Create, test, and publish your app using the same tools across platforms Platform Features

Web Apps versus Native Apps
We heart the mobile web!
Many native apps could be written as web apps
Mobile web is progressing fast and converging around Webkit and emerging web standards
For some apps, you need to go native for business or technical reasons
However, developing N apps for N platforms doesn’t scale

Titanium Mobile exists to help developers build native apps that…
Run cross-platform
Leverage common skill sets and a gorgeous dynamic programming language
Look, feel*, and perform native
Fit well into the native app ecosystem (local notifications, activities/intents, background services…)
*this is a fuzzy but important point – users can perceive differences and can tell when something isn’t quite “right”

Under the Covers
Titanium Developer === GUI for Python build scripts
JavaScript is statically analyzed, native project stub generated
JavaScript precompiled to bytecode (Android) or inlined in a generated C file (iOS)
JavaScript and native code bindings are shipped along with JavaScriptCore (iOS) or Rhino (Android) to interpret JS code at runtime

Typical Application Structure

For you web developers…
A “window” is analogous to a “page”
A “view” is analogous to a “div”
Ti.UI namespace provides many specialized controls (buttons, text fields, pickers, maps, scroll views)
UI objects are composed in JavaScript similarly to DOM fragments

View Hierarchy and Positioning
Modeled after iOS View Hierarchy
Views positioned relative to parent
Layout options:
Absolute
Vertical
Horizontal
Demo – Add a nested view structure to default app

Event Handling
Similar To JavaScript in the browser
Can use addEventListener on nearly any JS object
Can programmatically fire events on objects as well
Demo: A simple event handler

A Few Words On Workflow…
Target both platforms early (though not necessarily today)
iOS Emulator is fast for dev
Deploying to iOS device is slow
Android Emulator is S-L-O-W – keep it running!
Android devices are faster (better for dev)
