develop common part
• Use Native to develop the
weight lifting parts

SYMBIAN APP. DEVELOPMENT
Cross-Platform
August 11, 2013
The Symbian platform is the successor
to Symbian OS and Nokia Series 60; unlike
Symbian OS, which needed an
additional user interface system, Symbian
includes a user interface component based
on S60 5th Edition.

 The primary tools are:
o Symbian SDKs — with tools for application
development, including command line development,
these SDKs include documentation and a simulator
that enables testing on a Microsoft Windows PC.
SDKs are available for platforms up to and including
Symbian Belle.
o Carbide.c++ — an IDE specifically designed for creating
Symbian apps in C++. Based on Eclipse and the C/C++
development tools from the Eclipse CDT Project, Carbide.c++
provides tools to support Symbian C++ coding, building apps
for the SDK emulators, and performing on-device debugging
among others.
Cross-Platform
August 11, 2013

Other necessary tools for Symbian:
 S60 Third edition of fp2.
 Active perl5.6.1.638- MSWin32-X86
 Active python- 2.6.6.15-Win32-X86
 Carbide C++ V2.0
 Java 1.6.0

NATIVE APP DEVELOPMENT
 Basically you need to hire experts who can
 Build Android, IOS, BB, BlackBerry and Windows mobile
apps
 Devs should have experience to deploy apps on market
 Devs should have experience on various devices
 QA should know how to automate things on
devices/emulator
 Have concrete plans on
 What is Trial app?
 How does user upgrade?
 Use in app billing to have fine grained control
 Plan for risks if this is your companies first Mobile App

WEBKIT PLATFORM
 All Mobile Platforms have something common that is
a Modern Browser
 All these browsers are based on WebKit
 Moreover all these platform support showing
embedded browser in Applications (aka WebView)
 Strange enough all these WebViews provide hooks
from javascript to java and vice a versa
 In short WebView is the new Virtual Machine 

August11,2013
Cross-Platform
MAPPING TO NATIVE CODE
 Say Application is written in JavaScript
 The JavaScript code is running in Interpreter
 The Interpreter internally forwards calls to the native
code
 Limitation being the you can only map to subset of
code available on all target platforms. 

PHONEGAP PREREQUISTES
 Need to be acquainted with Android, IOS, BlackBerry, WebOS
 Need to be expert at HTML/Javascript or framework like GWT
 Need to be acquainted with JavaScript libraries like
 Jquery
 script.aculo.us
 Prototype
 Etc
 Or Ajax framework like GWT
 Use existing IDEs like Eclipse or Xcode, PhoneGap has no IDE

DIGGING DEEPER (ANDROID)
 Instead of extending a Activity, we extend DroidGap
 DroidGap internally uses a WebView to show
local/remote HTML/JavaScript/CSS
 This WebView has hooks to
 Call Java from JavaScript
 And Vice a Versa
 More like building Web 2.0 Applications
 But also calling some java scripts which allow
accessing native mobile resources e.g.
Geo, Database, File System, etc

TITANIUM PREREQUISTES
 Need to be acquainted with Android, IOS
programming
 Need to know JavaScript
 Use Titanium Mobile IDE to configure projects and
use Text IDE to edit the code

August11,2013
Cross-Platform
CHALLENGES AND ADVANTAGES
 Being Native is the biggest strength
 Limited cross platform api is a weakness
 Platform specific api leads to fragmentation within
code

August11,2013
Cross-Platform
HYBRID APP DEVELOPMENT
 Have Web Developers for Common UI
 Have native code experts for heavy weight lifting
 Use frameworks like PhoneGap to glue the above
two pieces
 Measure at every milestone to keep track of effect of
changes
 Use Automation to regress every layer

COMPARISON
Titanium
 Gives out native app
 API is more proprietary
 UI has Limitations
 UI will be fast
 Much better User
Experience
 Portal Code can not be
reused
 Extensions are possible
 Limited support for
HTML/Javascript
PhoneGap
 Gives out a mobile web app
 API is less proprietary
 UI possibilities are unlimited
 UI could be slow
 User Experience will get
better with enhancements
 Portal Code can be reused
 Extensions are possible and
easy to implement
Cross-Platform

CONCLUSION
 Webkit is the next Virtual Machine.
 Maybe Going where Java could not go
 HTML 5, CSS 3 and Javascript is future,but not
ready just yet
 HTML 5, CSS3 and Javascript to lessen the
fragmentation
 HTML 5 will compete with native components
Cross-Platform

CROSS DESKTOP APP DEV
 Following are options worth considering
 Nokia QT (webkit based)
 Titanium Desktop (webkit based)
 Adobe Air (flash based)
 Java
 Many more
