Why BlackBerry? Why WebWorks?
Web Apps vs. Native apps
• Different feel (or are they?)
• Users expect App life cycle
–
–
–
–
Driven by browser, but transparent to the user
Download
Install
Launch with icon
• Ultimately, the user doesn’t care it’s web
Web Apps vs. Native apps
• Am I web? Am I native?
• Key: where the app and the
platform meet
– Power of web design and
interaction
– Platform services should feel
cohesive
– Balance
NIBS
* Native Is Better Syndrome
-
Not a competition
Scale
Breadth of skills
Cross-platform
Still lags native, but gap is
closing
Basic Anatomy
• HTML 5
• + CSS3
• + Javascript
• + optional frameworks
• + Browser webview
• + package/deploy
_____________________
• = Mobile Web Application
It starts with the Browser
Acid3 Score: 100/100
CSS3 Selectors Test:
578/578
HTML5: 260/450
• BlackBerry has an industry leading browser
experience
– WebKit since 6.0, Provided by Torch Mobile team
•
•
•
•
Full HTML5, CSS3, Flash
position: fixed, overflow: auto
WebInspector
Optimized and hardware accelerated
– CSS3 animations
– Canvas
– JIT’ed JavaScript engine
• WebGL - One of the first mobile implementations
– HW accelerated
– Tunnel Tilt (http://github.com/blackberry/WebGL-Samples)
• Touch optimized Web frameworks support multiple platforms
– Examples: jQuery Mobile/UI, Sencha Touch, Dojo
• Improve the UI and functionality of your application
– Save time and money by using existing code!

Be Careful…
• Frameworks are built cross-platform
–
–
–
–
–
Even though it’s WebKit, differences in each
Mobile vendors look for differentiators
Varying levels of support
Framework behaviours may differ from platform norm
Test on all platforms
• Behaviour consistency
• performance
•
•
•
•
•
A Lightweight Independent CSS Engine
Micro Library for HW-accelerated visual affects
Entirely JS, separate JS files for each effect
Leverages CSS3, cross-platform
http://blackberry.github.com/Alice
<script src=“alice.core.js"></script>
<script src=“alice.toss.js"></script>
alice.toss({
id: "overlay",
duration: 2000,
origin: app.randAngle(-45,180)+’%’
+app.randAngle(-45,180)+'%',
random: 10
});
WebWorks Mission Statement
To create, as a community, a simple to use cross platform
SDK for Web Developers to package their Web assets as
a mobile application which has Secure access to deeply
integrated system level APIs
• Create standalone
applications with standard
web technology (HTML5,
CSS3, JavaScript)
• Framework to leverage
BlackBerry API’s in a secure
manageable container
• BlackBerry OS
5.0/6.0/7.0+, Tablet OS,
and future QNX powered
smartphones.
• User interface
• Powered by Web
• HTML and CSS
Your app
• Application logic
WebKit Engine
• JavaScript®
• WebWorks APIs
• Access to Platform

WebWorks Platform
BlackBerry Platform
BBM
Monetization

Security
PIM
Storage
Compression
Push
Background
Multi-Tasking
…
Tooling
• IDE vs. SDK vs. VIM & Browser
• Web very different from Native
• Edit -> Refresh, Rinse -> Repeat

Web Testing
• There are some emerging solutions:
– Weinre, JSConsole, Firebug Lite…
• Native simulators
– Big and slow
– 95% done, but STILL will need physical device
Web Testing. BlackBerry Style.
• Ripple emulator:

Testing in a browser like env.
Cross-platform! (PhoneGap, Mobile Web, …)
Simulate device APIs and sensors
F5, CMD-R
• Remote Web Inspector!
– Debug on-device
– Fully functional, including JS debugging

Ultimately, you go to device…
• Go to your device
options
– Security tab
– Activate the
development mode
– Set up a password
• Go to the browser on your device
– Go to Options -> Privacy and Security
– Enable Web Inspector
• Information will be displayed as to how to
connect to the browser
Open Source Commitment
