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)

messages from devices on the same connection. The GCM service handles all
