Bright Spots
- Phonegap lives up to its promise
- JQuery Mobile also lives up to its promise. It game me a better UI and excellent portability
- Translation from Java to Javascript is not too difficult.
- There exist real unit testing tools for Javascript
Disappointments
- <audio> tag and its API had spotty implementation (not working on iPad2 and Galaxy devices). Why it works on some devices (iPhone4 w. iOS6) is beyond me.
- JQM documentation needs significant improvement
- Apple process for releasing to iTunes store is both lengthy and bizarre
- Lost all i18n capabilities using HTML5 / javascript
Gotchas
- iOS upgrade on a device is irreversible
- stackoverflow.com is good source of info but can mess you up:
- right answer to a different problem
- right answer for a specific version of JQM (or phonegap, or css, ...)
- javascript type system is tricky.
- For example $mobile.changePage("problem_screen?newProblem=false") cases a transition to the problem screen. The parameter passed is 'false'. But 'false' evaluates to true. Huh? 'false' is a string that needs to be converted to Boolean false.
Unsolved problems
- Can all information for platform generation emanate from "config.xml?"
- What is the best way to detect and report javascript errors?
- What can be done to speed up application load time (5-8 seconds)?
Plans for the Future
I plan future versions of Twentyfour Challenge that include these features:- a new level using four numbers
- a "give me a hint" function during game play
