shoukry kattan - titanium mobile. cross platform mobile apps

Approach Mobile Web Native Cross –platform/Hybrid

Language HTML5, CSS,Javascript

Platform dependent. Objective C for iOSJava for Android J2ME for Blackberry

Write using one language. “Compiled”

or “Interpreted” to native code for the platform.

Native UI No. You can “fake it” with

a less rich experience

Yes Yes

Server communication

Yes Yes Yes

Access to native APIs and features (Photo gallery, Phonebook, etc.)

No Yes Yes

Access to Hardware (Accelerometer, GPS,Camera,etc)

No Yes Yes

Develop for multiple platforms:

Using the same Technology and same codebase.

Team with the same skillset, expertise.

Write once run anywhere.

Which leads to :

Reduced development time

Reduced development cost

Reduced development effort

Free

Open source

Use Javascript to write native applications

Active and big community

Commercial support, custom development and modules are available from Appcelerator.

Companies using Titanium

Compile time : Pre-compiler:

JavaScript code is optimized, dependency hierarchy of APIs used is created.

Front-end compiler:The appropriate platform-specific native code is generated along with projects and specific code is built to compile Titanium for a given platform compiler.

Platform compiler & packager:Using native tools for the particular platform , code is compiled and application is packaged.

Runtime : Javascript is interpreted at runtime with hooks to execute native code (Javascript bridge)

Standard and familiar web model (MVC)

APIs: UI APIs

Phone APIs Media

Database

FileSystem

Network

Accelerometer

Geolocation

Many more …

Native UI components

UI Components are:

Windows (Hosting views)

Views (Draw conent on screen, Ex. Image View)

Widgets (Views with actions, Ex. Button)

Video

Sound

Camera

Accelerometer

Maps

The same code renders differently depending on the platform

Build and test the application on multiple platforms from day one if possible

Separate business logic from UI construction

Component Oriented design

Your application is a library of Application specific components

Use custom events instead of component and platform specific events.

Use built in Titanium features to handle multiple platforms, screen resolutions and densities
