VIII.  Modern Android Design [pakoch@; Adam Koch, Android Developer Advocate]

1.       Updates

1)      Design patterns: navigation, navigation drawer, unofficial patterns

①  Action bar: consistent bar (component: brand/app icon, drop-down spinnup, search, movie), Action Overflow (extra options)

②  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)

③  Navigation Drawer Interaction: introduce the drawer on first use, give the user a quick peek, highlight the current screen)

④  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

①  Device variety- screen size, resolution, vertical to horizontal support

②  Why responsive? – android:layout_width=”match_parent”

③  Combination- side-by-side

④  Fragments

⑤  Master/Detail Flow template-> File > New> Android Object

⑥  SlideingPaneLayout- enough room then show everything, if no, then slides to the right (e.g. Google I/O 2013 app)

⑦  Dimension files- page_margin, headline_text_size, etc)

3)      Pure Android: Why Android/Holo?, Balancing Brand andPlatform Consistency

①  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)

②  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)

③  Quality Checklist

④  Localized screenshot, video, etc

2)      ABC of Marketing Application

①  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

②  Simplify Sign-in w/ G+- drive downloads/ increase engagement

③  Increase downloads through Play badging- e.g. Get it On Google play
