1. AN ASPECT-ORIENTED ARCHITECTURE FOR HANDLING VARIATION ACROSS MOBILE PLATFORMS Proposed by: Chokchai Phatharamalai Advisor: Dr. Paul Janecek

2. Agenda Problems Current Solutions My Solution Demo Conclusion

3. Problems Mobile applications always need to support various platforms Developing applications that are capable of running on a variety of mobile platforms is hard.

4. Why not use Java? Java is “Write Once, Run Anywhere” That’s true! But not in JavaME ◦ JVM is embedded in hardware, you can’t upgrade (different CDLC and MIDP) ◦ What if JVM have bug in itself?

5. Why hard? Different screen size Different input keys Different versions of platform ◦ (such as CDLC and MIDP version)

6. Current Solutions Multiple copies Quick and dirty: Multiple copies Software Product Line engineering Slow start but long run: Software Product Line engineering

7. Multiple copies App. A Hey guys! I have a bug. … …

8. Software Product Line engineering I use domain version 1 I use version 2 Complex

9. My Solution To separate

10. My Solution To generalize generalize

11. My Solution To derive Link

12. My Solution To evaluate

13. Implementation I use Aspect-Oriented Programming to implement the Driver AOP can hack intercept method call and hack classes

14. Output

15. Evaluation Performance Analysis Metrics Result Analysis Reusability of Code Less than a millisecond! Reduce complexity! 100% reused while porting games!

16. Future Future work ◦ Alternative Approaches for Gray Zone ◦ Duo Standards Recommendations ◦ Aspect-Oriented Metrics ◦ Aspect-Oriented Documentation
