Hybrid vs. Native
 Differences
 HTML –
 Native –
 Hybrid –
 Limitations
 HTML –
 Native –
 Hybrid –
Rapid, cross-platform user experience (Content)
Power and device features (Games)
Combine HTML + device features + available in Stores
No DNA sequencing, Reasonable data models
Keep animations above 30 frames
Not by handset means
Same as HTML
7
How you dare to use it?
 There is a war out there
 Started with Steve Jobs vs. Flash
 Not only mobile, but smart TV, XBOX, Playstation
 It‘s everywhere
 Not only developers, but in each company

Use 3D transitions
Double-Click problem

“tabstart“ or “singletap“ event
DOM Pollution

TOP 6 management items
 Time
 first version 70 - 80% of dual pure native development
 all other release time 50%
 Bug hunting
 fix only once
 Design
 Prototyping
 Start small, quickly add
 Not sure if design follows function on mobile

Conclusion
http://www.sencha.com/blog/5-myths-about-mobile-web-performance/
 no-one is trying to do DNA sequencing on an iPhone
 most apps have a very reasonable response model
 the user does something, then the app responds visually with
immediacy at 30 frames per second or more, and completes a task in
a few hundred milliseconds

Think for yourself!
Hybrid development covers 90%
of B2C Apps

Agenda
 DEVELOPERS 4 BEST FRIENDS
 Framework
▪ Wrapper ▪ Tester ▪ Caretaker
25
Developer 4 Best Friends
 Developer needs:
 a framework
 a community to ask
 a real pro for code reviews
 a testing framework (same language)
26
Framework: Sencha Touch
 Developed for 5 years, based on EXTJS
 real framework
 MVC (upcoming MVVM)
 Data-binding
 full speed animations
 Knockout JS
 Angular JS
