  • 1. MobFest February 2009 Aaron Chan Business Developer Cross Platform Development & Porting
  • 2. The causes What causes fragmentation? The Fragmentation Problem
  • 3. The causes What causes fragmentation? Hardware differences, models & markets Verification of handsets /java New JSRs and APIs The speed of the standards process Manufacturer differentiation Handset customization Handset variation & language differences Why fragmentation?
  • 4. Strategies How to deal with fragmentation (1)
    • A) The brute force method
    • Create reference versions
    • Create 10-15 primary ports
    • Create 50-100 secondary ports
    • Involves code washing, pre-processing search & replace expressions, various manual adjustment.
    • Typical for Java applications deployment
    How to deal with fragmentation
  • 5. Strategies
    • B) The transcoding method
    • Create reference versions
    • Create a port for each OS
    • For each phone in each group, carry out transcoding using device profiles
    • Normally, the source code is often sent elsewhere for treatment
    Or use transcoding
  • 6. Strategies
    • C) Advanced compiler technology
    • Make the code:
    • Transformable
    • able to carry out complex analysis
    • able to perform static checks
    • form an application syntax tree
    • A compiler back-end for each OS, adapted to optimally output code for each target platform, in analogy to GCC technology and its back-end(s)
    Which is what we’re gonna be showing you here today! Or transform
  • 7. MoSync MoSync a cross platform (Symbian, J2ME, Windows Mobile and others) tool that makes it easy to port, update and create applications from one mobile platform to another . MoSync removes bottlenecks in developing and deploying and allows dynamic services to be created simply . Mobile development has never been easier and porting is history! The solution
  • 8. One source code direct to Symbian, Java and Windows Mobile
    • Pre-processer directives
    • Abstraction layer
    • Device analysis
    • Time to demo!
  • 9.
    • The Eclipse IDE
    • Project window
    • Building the project
    • Testing in the emulator
    Demo “Simple application”
  • 10. Other examples “advanced application”
    • With permission from with author Eric Chahi
    • Source interpreter
    • SDL stub ported in 4 hours
    Porting Another World* into MoSync * The game is known as Out of this World in the US and Outer World ( アウターワールド ) in Japan http://www.apple.com/macosx/server
  • 11. “ Building Ruby”
    • Ruby for Symbian, Windows Mobile (and java)
    • Open source language
    • Ported in 1,5 days
    A Ruby interpreter built on MoSync
  • 12. How to automatically port to hundreds of phones The solution
    • Single projects vs. multiple projects
    • Building for many devices and O S s
    • Using the Finalizer
      • generating scripts/criteria
      • running script
      • defines, pre- and post-steps
      • output structure
      • saved-in project
  • 13. Developing for Symbian devices w/o C++
    • N e w technology means new languages
    • Different front-ends
    • C/C++
      • J ava
      • Objective C
      • Fortran/ADA/Small Talk/Erlang/
      • n ew
    • Scripting languages (python, ruby)
    • Different back-ends
      • iPhone
      • Android
      • Moblin
      • Flash/ECMA script/weird
      • new
