Mobile Devices

Handheld electronic device with limited processing power and connectivity commonly use by end-user consumers

why mobile device
Why Mobile Device ?

Mobile devices has become increasingly popular during the last 10 years.

Estimate mobile subscribers around the world 2.7 billions.

Currently Malaysia alone have has about 11 millions of mobile phone users

a figure which expected to increase over the years.

why mobile device8
Why Mobile Device

Advancement of cellular technology has allowed

Greater data transfer

Faster processing power

Greater interactivity

Wider connectivity

early mobile application
Early “Mobile Application”

Limited processing power

Relies heavily on a server-side language

Depends on external browser

Characteristic by the use of WML, XHTML, cHTML technology

Does not actually 'run' on the mobile device.

early mobile application10
Early “Mobile Application”
  • Relies on the server-side to provide both processing power and User Interface
  • Little or no client-side processing
  • No client side record/database storage – everything on the server
  • Solely depends on internet connection
emerging trends of mobile application
Emerging Trends of Mobile Application

Runs natively on the mobile device itself

Does not rely on external browser

Depends more on Web Service API (SOAP/XML-RPC/REST) rather than the website itself.

Concentrates more on usability and content delivery

why do we need native network mobile application
Why do we need Native Network Mobile Application

Easy to deploy in commercial sense

Tightly integrated into user interface

Does not rely on external browser

The application can store data on mobile phone

Faster retrieval and response time

The application can access mobile phone functionalities (camera/sms/caller-id/files)‏

examples
Examples

“Jeffrey wants to create an application which enables him to share photos taken from his phone camera to some of his friends”

Can it be done with WML/XHTML based mobile application?

‘Virtual’ Serial COM port (on PDA)

ways mobile internet application communicate16
Ways Mobile Internet Application Communicate

High Level (The BEST Way!)

Achieve through the use of Web Services

  • XML-RPC
  • SOAP
  • ATOM api
  • Representational-State Transfer (REST)
why web services is the best way
Why Web Services is the best way?
  • Uses distributed computing concept
  • Widely accepted as a ways to publish API
  • Portable, Web Services only relies on HTTP/HTTPS availability
  • Becomes an Emerging standards of publishing services (W3C, RFC 4287)
organization that uses web service
Organization that uses Web Service
  • Google.com (ATOM -GData, SOAP)
  • Yahoo.com (SOAP)
  • Amazon.com (SOAP)
  • Wordpress.com (XML-RPC)
  • Haze.net.my (REST)
  • Foxrate.org (XML-RPC)
organization that uses web service19
Organization that uses Web Service

Amazon.com

Publish Web API to enable developers to create application that can list latest Amazon product, price comparison and heavily discounted and popular items

  • Flickr.com

Uses web service API to enable its users to post/update photos using any application.

DB

DB

Procedure stored on the server

XML-RPC API Server (http://foxrate.org)

Result() = 353.71

currencyConvert(USD,MYR,100)

Less of 1KB data

Less than 1KB data

User Interface is inside the phone

web service is better because
Web Service is better because
  • It separates the developers work and the service providers work
  • Developers only concentrates on their best expertise, developing mobile clients.
  • Developers does not need to maintain the information itself
web service is better because25
Web Service is better because
  • In mobile application, size DOES matter!
  • Data transfer need to be optimized for faster response time (latency) and cost)
  • Locally run Mobile Internet Application that uses Web Service do just that!
bandwidth data transfer efficiency
Bandwidth & Data transfer efficiency

Typical WML Application

foxrate.org

Request website

foxrate.org

Website (interface) displayed

index.wml – 4KB

foxrate.org

User request currency exchange (process.php) – less than 1KB

Typical WML Application

foxrate.org

Result displayed

result.wml (3KB)

Total Data transfer = 4KB + 3KB + 1KB = 8KB

Web Services is 4 times smaller than a typical WML application !

slide29
Why?
  • The main reason is the user interface of WML application is stored on the server not client
  • By using web service we are free to create our own user interface independent of the service provider.
wml drawbacks from commercial aspect
WML Drawbacks from Commercial Aspect
  • WML application are hard to sell
  • Hard to distribute
  • Require constant maintenance (server)
  • Hard to customize on the mobile phone part (different vendor wants to put their own logo, endorsement)
  • WML application can’t use phone features (camera,bluetooth, GPS, InfraRed)

What Next ?

Location Base Application (GPS)

  • Car Navigation
  • Fishing Spot Finder
  • Speed Warning (GPS Auto)
  • GPSolat

More mobile phones are equipped with GPS receiver, it’s the latest trend!

gpsolat prayer time base on gps
GPSolat – Prayer time base on GPS
  • Prayer time is different according to location, season and direction.
  • GPSolat uses location data to determine the Kiblah direction and users’ current location
  • Base on that it can calculates prayers time.
  • No need to worry about prayers time when travelling anymore!!
internet mobile application sdk
Internet Mobile Application SDK

You can create Internet Mobile Application using any of these platforms

  • JavaME (http://sun.java.com/javame)
  • Symbian (http://forums.nokia.com) (Nokia)
  • .NET Compact Framework (http://msdn.microsoft.com/mobility/netcf/) (PDA)
javame
JavaME
  • The best SDK for learning
  • Supported by almost all modern phones
  • Has great documentation
  • Uses Java
  • Has a lot of libraries
  • Implementations guaranteed to support HTTP/HTTPS protocol for communication.
  • Portable
net compact framework
.NET Compact Framework
  • Great for people who are familiar with .NET
  • Supported by Windows Mobile PDA devices only
  • More powerful than JavaME
  • Tighter integration with device (Microsoft+Microsoft)
symbian
Symbian
  • Uses C++
  • Harder to code compared with others
  • Very close to hardware implementation
  • Limited device, only supported on some Nokia and Sony Ericsson Smartphone
why develop mobile application
Why Develop Mobile Application?
  • The Desktop application market has been saturated and controlled by bigger companies. (i.e nobody uses other application than MS-Word, Powerpoint)
  • Mobile devices is the new playground.
  • Opportunities to develop localized content
  • Huge marketplace, can compete with each other fairly.
  • Niche Market, you can sell through telcos
places to publish mobile application
Places to publish Mobile Application
  • Handago.com
  • GetJar.com
  • Payloadz.com
  • PocketGear.com
  • MypdaCafe.com
