Mobile Application Development Using Open Source Software
Mohammad Hafiz Ismail

Outline
• • • • • • • Introduction What is (not) mobile device? Why mobile device? Types of Mobile Application Why Open Source? SDK, Libraries and Utilities Demo

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

Examples of Mobile Devices
Mobile Phones / Smart Phones PDA (Pocket PC / Palm) Internet Tablet Navigation Device

What is not Mobile Device Laptop Personal Computer Game Console

Why Mobile Device ?
 Mobile devices has become increasingly popular during the last 10 years.  Estimate mobile subscribers around the world 2.7 billions.

Devices Popularity

(Mobref,2006)

Why Mobile Device
Advancement of cellular technology has allowed      Greater data transfer Faster processing power Greater interactivity Wider connectivity Allow greater customization

Types of Mobile Application
Email Applications Video Streaming Games News reader Instant Messenger Application Productivity / Utility Location Base application Home/Security Monitoring Application

CAN BE DEVELOPED USING OPEN SOURCE SOFTWARE

Why Open Source?
• Greater access to the development kit • Lower development cost • No 'black boxes' are possible

Java ME – Java Micro Edition

JavaME –Java Micro Edition
• “The Most Ubiquitous Application Platform for Mobile Devices” • Continues Java concept – “Write once, Runs Anywhere™” • Supported on most mobile devices • Sun has open sourced JavaME platform – phoneME

JavaME – Java Micro Edition
• SDK can be downloaded from – http://java.sun.com/javame • GPL ‘d JavaME implementation – http://phoneme.dev.java.net • Open Source release works under Windows, GNU/Linux, Mac OS and other Unix-like operating system.

JavaME –Java Micro Edition
Specification divided into : • MIDP - Defines GUI API, Interactivity • CLDC – The underlying core class, VM

JavaME – Java Micro Edition

Java ME – Java Micro Edition
Extended features added over time to phone and to the platform JSR 75 File System and PIM JSR82 Bluetooth JSR120 Wireless Messaging API (WMA) JSR135 Mobile Media API (MMAPI) JSR172 Web Services JSR179 Location API JSR256 Sensor API (Acelerometer)

Java ME – Java Micro Edition
• These extensions are added by the vendors and made into JavaME through Java Community Process (JCP) • Each extension specifications are made public so it could be standardized across vendors

Java ME – Java Micro Edition

Java ME – Java Micro Edition

Java ME - Advantages
• Widely supported on variety of mobile devices • Third Party library support
– J2ME Polish – Bouncy Castle Light Crypto

• Relatively easy-to-use • “Highly “portable

Java ME – The Drawbacks?
• Device Fragmentation
–> –> –> –> –> Different Different Different Different Different screen-size capabilities Navigation key layout number of buttons fonts

• Multiple JSRs cover various capabilities • Defeats the purpose of “Write once, Runs Everywhere”

Python for Series 60

PyS60
• Python bindings for Series 60 Symbian Platform • Initiative by Nokia • Dual Licensed
– Apache License 2.0 – Python Software Foundation

• http://pys60.sf.net • http://opensource.nokia.com/projects/pyth

PyS60

PyS60
• Can be written as a normal python program file .py using standard python interpreter • Does not need separate SDK • Supports native UI and widget • Can be extended using C++ • Package - *.sisx like ordinary Symbian application

PyS60 - Disadvantages
• Supported on Nokia phones only • Still under BETA, many features broken • PyS60 runtime are required to be installed on the phone • Eats up memory • Not many application written with pys60
