Amazing Mobile
Platforms
10
Which is great and
exciting!
11
only how do we target
all these cool platforms?
12
Well, you could build
native, but
•

Which platforms do you choose?
•
How many codebases do you want to (or even can you) support?
•
How long will it take to build native on N platforms?
•
How much effort will be duplicated?
•
What if you bet on the wrong platform?
•
Who writes the code? Hire out? Retrain/retool yourself or your devs?
13
The Web Is An Option
•
and should be preferred when feasible
•
Mobile browsers are progressing fast and converging around WebKit
•
But there are limitations
•
Native apps are inherently more capable than web apps
•
Native apps run faster and smoother on resource constrained devices
14
Ideally, we build cross-
platform native apps
15
but we don’t want to
“write once, suck
everywhere”*

X-Platform
Requirements
•
Target multiple platforms from a single codebase
•
Apps must feel like they belong on the platform
•
Apps need to perform like native
•
Bonus: Open source and extensible
•
Bonus: Use skills we already have
Hmmm, I wonder if he has a specific technology in mind
17
Enter Titanium
Titanium is an open source framework for
building native mobile (or desktop)
applications using open web technologies
(JavaScript - optionally HTML and CSS)

Who Uses Titanium?
•
NBC Universal
•
PayPal
•
MTV
•
Anheuser-Busch
•
Computer Sciences Corporation
•
Intridea (Oil Reporter)
•
100s of Titanium apps hitting the stores each
month (should soon eclipse 1000/month)
22
Titanium Architecture

•
Desktop is HTML
focused
•
Can use other
scripting languages
•
Mobile: JavaScript
interpreted at runtime
•
JavaScript API >>
native APIs
23
What Titanium Mobile is
not:
•
Not a native wrapper around a web view
•
However, you do have a web view component for HTML/CSS UI if that is your preference
•
Your JavaScript code is invoking native APIs for UI and other native functions
•
Think MacRuby/Hot Cocoa on the desktop or some AAA mobile games which ship with a Lua interpreter
