“Titan”
• Breakdown pricing; Core, iOS, Android • Factor in platform,
form factors • Include costs for AppStore submissions, re-submissions Pricing
Design Retina Dimensions No font details Designed for iOS
• Acknowledge OS differences (Nav, back buttons) • Educate the
client / designer • Give examples / links to tools • Send them images folder structure Design
• Real devices • hdpi, ldpi, etc • Multiple OSs
• Don’t forget 2.3.x Testing
• TestFlight • Installrapp Delivery
• Free, easy • Fast • Google APIs, Play support,
simple “hack” • Great GPS, Mapping tools • Android first! Genymotion
Android development before Genymotion
Android development after Genymotion
• See changes (almost) instantly • Works on simulator, emulator,
device • Instantly resolve platform differences as you go • Don’t get “locked in” to one platform • But, there be dragons! Use TiShadow / Liveview
• Separation of business logic & UI • Isolate code
with OS_IOS, OS_ANDROID • Platform, formfactor specific elements • Only relevant code / files are included in a build • Makes cross-plaform easier Alloy
• Separate business logic • APIs, Social, GPS etc •
Better memory management • Easier to re-use commonJS
• Define granular classes • Test layouts on both platforms
• app.tss for global classes • “reset” for Android • Platform specific overrides app.tss, classes
• Use dp/dip (ti.ui.defaultunit) • Avoid fixed widths / heights,
unless.. • Top, Left, Bottom, Right is the same on all devices • %age and fluid layouts • Dynamic buttons Flexible layouts
• Very granular • Long, NotLong, Landscape, Portrait • Keep
it simple • Retina images and Android ! ! Density Images
• iOS style stretchable images • Splash screens • Android
version of leftCap, topCap • Editor built-in to Android SDK • http://9patch.fokkezb.nl/ ! 9-Patch images
• Reduce “over the bridge” calls • TableViews - classname
• ImageViews vs Views • ListViews over TableViews • Reduce views, especially in tables Android Performance
• Views = screens • Swipe between (great for prototyping
/ demos) • Disable manual swiping • Simple view stack management • Super-fast and smooth animation on Android ScrollableView Navigation
• Simple “inheritance” for Alloy Controllers • Re-use controllers, views
• Create cross-platform template wrappers Base Controllers
• <require src=“controllerName”/> • Latest Alloy supports require/widgets with children
• Create a wrapper template controller Require templates
• Little-known feature of Alloy • Override Alloy Tags to
provide per-platform support • Create your own tags! • Not a replacement for Widgets, just different The “module” attribute
None
Thank you!
