SYMBIAN APP. DEVELOPMENT

April 10, 2023

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.

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 deployment

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

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.

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

CHALLENGES AND ADVANTAGES

Being Native is the biggest strength

Limited cross platform api is a weakness

Platform specific api leads to fragmentation within code

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

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
