Hmm. Is it too late to join buy4lib? e.g. iPhone app written in Cocoa requiring download via the App Store build web app? native app? “Most of the folks I know in app development are moving to standardization on web versus device specific development.” Linda Woods AT&T Education Advocate Industry & Mobility Application Solutions 2009 Handheld Librarian Online Conference This just out… an iPhone OPAC. Download it from the App Store. What? Uhhh. I just bought a Nexus One. Loser! The Tao of mobile web (app) design A mobile web app should do one thing and do it well. A mobile web app should be as simple as possible, but no simpler. standards compliance web usability design minimalist design design and testing cross-browser cross-platform a good mobile web app typical single-interface that-does-everything library web app 1 1 4 Simple is as simple does. iPhone web apps (according to Apple*) * Content on iPhone: Is It a Webpage or an Application? Three categories: compatible with Safari on iPhone optimized for Safari on iPhone iPhone web application W3C standards compliant - no framesets or - unsupported technologies (cough, Flash) If it doesn’t look exactly like an iPhone app it can’t be any good! 2 iPhone web application tool kits iUI: iPhone User Interface Framework iWebKit: ditto http://code.google.com/p/iui/ License: BSD http://iwebkit.net/ License: GNU LGPL JavaScript libraries, CSS code, images… I didn’t have to start from scratch. jQTouch (jQuery plugin) http://www.jqtouch.com/ License: MIT iUI iWebKit jQTouch “Moore’s Law doesn’t apply to batteries…as we’re now going into mobile…the cycles count.” Douglas Crockford* Gee, I love what jQuery can do, but maybe server-side processing is the way to go. * Quoted in “Coders at Work” by Peter Seibel, pg. 100 [11:45] <jkeck> jquery++ [11:45] <mjgiarlo> @fight bacon jquery [11:45] <zoia> jquery: 2090000, bacon: 106 [11:45] <mdoran> whatever Handheld emulators/simulators Operating System Generally come with handheld OS SDKs webOS (Palm) http://developer.apple.com/iphone/ Android (Google & Open Handset Alliance) http://developer.palm.com/ iPhone (Apple) Software Development Kit http://developer.android.com/ Web-based simulators (be leery) Opera Mini Simulator – good http://www.opera.com/mini/demo/ TestiPhone.com – absolutely worthless Oooohh Handheld emulators/simulators Android Palm iPhone Opera Mini Browser compatibility – don’t skip this Internet Explorer Firefox Chrome XHTML/HTML/CSS validation XHTML/HTML CSS Accessibility Get right with these before you move on to platform compatibility. Mobile design – platform compatibility viewport Mobile design – platform compatibility Larger buttons for finger tapping Mobile design – platform compatibility 2 Test it on the real thing (handset), too! Just need to… test… my app…. one… more time Or, as a last resort… Borrow from colleagues Don’t forget the documentation! Mobile/handheld developer sites have useful information on how to “design for small” Read it Seriously. Read it. A viewport? Who knew? It’s a small world after all. Example docs and websites Reading? I just want to code! iPhone Principles and Guidelines for Creating Great iPhone Content iPhone Human Interface Guidelines for Web Applications Google Groups: iPhoneWebDev Others Opera Mini Developer resources many, many, more… still more… “Deliver relevance -- expectations are high and you can only dazzle once.” Cindy Cunningham, OCLC LITA 2009 National Forum Patrons can be persnickety.
