VIII.  Modern Android Design [pakoch@; Adam Koch, Android Developer Advocate]
1.       Updates
1)      Design patterns: navigation, navigation drawer, unofficial patterns
  Action bar: consistent bar (component: brand/app icon, drop-down spinnup, search, movie), Action Overflow (extra options)
  Navigation: spinner (drop-down navigation item), fixed tabs (underneath action bar), scrollable tabs, drawer (primarily for main app navigation, Action Bar stays in place, Drawer overlays content)
  Navigation Drawer Interaction: introduce the drawer on first use, give the user a quick peek, highlight the current screen)
  Unofficial patterns: Fading Action Bar (introduced in Google Play Music, part of other Play apps as well), Swipe to Refresh (experimental pattern, currently only used by Gmail app), Action Drawer (used by Google+, One Today for app notifications, shows scrollable list of items), Cards
2)      Responsive design: why responsive?, SlidingPanelLayout, Other tips
  Device variety- screen size, resolution, vertical to horizontal support
  Why responsive? – android:layout_width=”match_parent”
  Combination- side-by-side
  Master/Detail Flow template-> File > New> Android Object
  SlideingPaneLayout- enough room then show everything, if no, then slides to the right (e.g. Google I/O 2013 app)
  Dimension files- page_margin, headline_text_size, etc)
3)      Pure Android: Why Android/Holo?, Balancing Brand andPlatform Consistency
  Why design Android/Holo?
A       Better User Experience- Platform consistency, intuitive use of app, improved usability, engaging content-first design)
B       Easier, More Robust Technical Implementation- designed to handle hardware variations such as screen sized, densities, on-screen vs. hard navigation buttons, OS version and device compatibility)
C       Beautiful, Flexible Design- efficient use of white space and typography
D       Brand consistency- split into IA, IxD, Visual design
4)      Examples- Fancy (card base, scale on a different sizes), Expedia (split screen into 2 for tablet), TED (action bar, thumbnails)

IX.     How to build a great Android app [khmin@;Kyunghwan Min, Korea Lead, Apps & Games Google Play]
1.       Key takeaways
1)      ABC of Building Application
  all screen size adaptable
  Android design guidelines (esp. Action Bar, Navigation, Pure Android)
A       #1: Action Bar- delete unnecessary items
B       #2: Navigation (Up vs. Back)- in game, back button-> pause
C       #3: Pure Android- use Google identity icons (e.g. no text included icon, no right arrow, use API)
  Quality Checklist
  Localized screenshot, video, etc
2)      ABC of Marketing Application
  Create an awesome Play store listing
A       Feature Graphic- need a promotion banner (device image, screenshot)
B       Description, Title- use user query, be careful in using promotional description
C       Icon- use unique representative icon
  Simplify Sign-in w/ G+- drive downloads/ increase engagement
  Increase downloads through Play badging- e.g. Get it On Google play
  Immediate Play- get ready for users to start playing games right away (include GUEST LOGIN icon)
