August Chicago Mobile Meetup talk 8-25-11
- 1. App-ifying or monitizing your present business web resources Using HTML5, Jquery Mobile and PhoneGap
- 3. This talk is not about one platform that's better
- 4. This talk IS about my experiments with these platforms
- 5. Hypothesis + Control + Variables (html5, jquery mobile, json, phonegap) = you make the call
- 7. My dad would like an easy offline way to figure out which low-sodium drinks he can have because he still likes frappes and cappuccinos
- 9. Lack of user friendliness in corporate data
- 10. I have web-development skills, but not mobile skills
- 12. If I wanted to build a mobile app to sell, I would probably take the traditional route of native.
- 16. localStorage.setItem(“The plaid fox jumped over the granite sky.”)
- 17. Now “The plaid fox...” is set like a cookie, but I don't need that, I need an offline database in the browser.
- 18. Your phone can hold strings...but relational information (pepsi-can-40mg) is what I want in client-side webpage storage.
- 21. Can also be nested, but for now the database table has 4 columns: id, drink, size, and caffeine which we can add to, extract from, and search. It is permanently stored in the browser until the user physically clears their localstorage cache.
- 23. var getdrink = localStorage.getItem(drinkadd);
- 25. if (getdrink["drink"] == "coke") …
- 26. “The drink you selected has “ + getdrink["caffeine"] + “mg of caffeine!”
- 27. The javascript object turns into a string to go in
- 28. It gets parsed and back to an object coming out
- 29. This is how I remember the drink information.
- 35. App sure is a bulky size and slow to load.
- 36. Degrades nicely for Blackberry, IE, Opera Mini, etc...but at a kb cost
- 37. Possibly unorthodox at this time (if jqmobile runs all the links, operations such as a back button, form submitting and javascript validation, using the # in links, and css changing take some playing around with)
- 38. Building for one platform, roll your own style...?
- 43. Find a tutorial you trust and stick to it to the letter.
- 44. It will compile multi-page websites into an app, but single page (inner linked divs) yield quicker performance
- 45. It needs an index.html
- 46. Any error anywhere will cause Android to crash your app – not forgiving like the web
- 48. Still need a mac for ios platforms
- 49. Blackberry = whole new ballgame – you should really study this platform before you build for it
- 50. Still need to configure your Androidmanifest.xml file for permissions – ie, add internet access perm before adding a link
- 51. “Export to signed app” is a nice wizard feature.
- 54. ADK/ADT plugins = all
- 55. Jslint, phonegap, javascript development tools
- 56. Apache Ant, but not Ruby
- 57. Java 6.0
- 58. PhoneGap 1.0
- 61. Titanium = a javascript app compiler in its own software package. Not intuitive on how to fix bugs or general “how do I do it”
- 62. Zepto.js = “jquery for only mobile safari and chrome”. Lite, but with transition effects.
- 63. Webdb / SQLite = I was initially put off by the “browser wars” lack of support. This is a good second option for right now in phone storage.
- 65. Restaurant menu or health concerns app
- 66. Event app (schedule of events)
- 67. Where information may change frequently?
- 68. Parsing a feed from a big cms site into an app?
- 70. What's good for making money with in-store apps doesn't work with “quick fix tools” such as web app technologies
- 71. You can do a lot of native things with web app compilers like PhoneGap, but you still need native intelligence to implement those in.
- 73. By pushing 3 buttons (brand, flavor, size) it keeps track of what and when you drink in a day when you close the app/browser.
- 74. It tells you when you are close to your limit, and what drinks will be too much caffeine for you at this time.
- 75. 3 versions: adults, pregnant women, kids and young teens
- 76. Links to medical research and the companies' nutrition pages
- 77. All versions also available En Español
- 78. Included brands: Coke, Vitamin Water, Pepsi, Sobe, RC, Snapple, Arizona, Panera, Tim Hortons, Dunkin Donuts, Caribou, Starbucks, Seattle's Best, Jarritos (Mex), Guarana Antartica (Brz), Wahaha (Chn), Dannon Yogurt, Haagan-Dazs, Hershey's, Anacin, Excedrin, Vivarin, Monster, Red Bull, Jones Soda, Yerba Mate, and many other energy/specialty drinks.
- 81. Big thank you to Gregg and Kelly from the Chicago Mobile meetup for this chance!!!
