Android KitKat 4.4 introduced several design changes including using a neutral gray color scheme instead of blue, enabling applications to use the full screen in two modes, and adding translucent system bars to display more application content. It also defined new gestures like a double touch drag for pinch zoom and incorporated support for step detection and counting sensors. The document provided background on Android's history and architecture before detailing these interface enhancements in KitKat.

3. HISTORY OF ANDROID
 Android Inc.founded in Palo
Alto,california ,united states in October
2003 by Andy Rubin[co-founder of
danger ],rich miner[co-founder of
wildfire communication Inc.],nick
sears[once VP at T-mobile],
and Chris white[headed design and
interface development at web TV] to
develop.

4. WHAT IS ANDROID?
• It is a open source software platform and operating
system for mobile devices
• Based on the Linux kernel
• Developed by Google and later the Open Handset
Alliance (OHA)
◦ Allows writing managed code in the Java language
• Android has its own virtual machine i.e. DVM(Dalvik
Virtual Machine),which is used for executing the
android applicatn.
• Google purchased the initial developer of the
software , android incorporated in 2005.

7. ANDROID ARCHITECTURE
The software stack is split into Four Layers::
• The application layer
• The application framework
• The libraries and runtime
• The kernel

9. KitKat
 Android 4.4 (code-name
KitKat) was released on
October 31.
 The android market has
often suffered from
fragmentation as each
vendor was left to implement
its own skin for Android. With
KitKat we are perhaps
seeing the start of a core set
of UI guidelines for the
mobile OS.
 The following is a summary
of some of the key design
changes introduced with
KitKat that should be
considered when designing
modern Domino applications.

10. Android Market Share
 Strategy Analytics estimates
that in the 3rd quarter of 2013
Android devices accounted
for 81% of global shipments
for smart phones.
 While 200 million devices
upgraded to iOS 7 in the first
5 days, KitKat is likely to see
a much slower uptake with
initial availability limited to
the Google’s own Nexus 5.
 Clearly we need to keep a
close eye on everything that
Android does as it slowly
takes a stranglehold on the
smart phone market and its
users set expectations for
mobile application design.
Android
82%
iOS
13%

11. Android kitkat 4.4 - What is
new in Android Update ?

12. Branding Color
 As with iOS7, we see a move from
the familiar blue of the Android holo
color scheme to a more neutral
grey.
 This change is designed to allow
applications a greater choice of
color schemes that will not clash
with the entire screen content
• Also gone is the use of the blue
accent color to denote the touching
of hotspots on the screen. Now
when something is touched its
background color slightly darkens or
lightens.

13. Full Screen
 Android KitKat has improved
support for letting
applications use the entire
screen.
 The Lean Back approach is
used when the user will have
minimal interaction with the
content. A simple touch
anywhere on the content will
cause the bars to reappear.
 A new Immersive approach
is used when a higher level
of interaction is expected. A
swipe from the edge will
cause a bar in that location
to reappear.

14. Translucent Bars
 Similar to iOS 7 we see a
move to continuously display
more content from the
application through the use of
translucent system, action,
and navigation bars.
 Note: The use of translucent
bars are an option for
applications, not a
requirement.

15. Gestures
 The double touch gesture
has now been formally
defined to scale up the
targeted area to fill the
screen.
 A new double touch drag
gesture operates similar to
pinch zoom gestures.
Dragging up will decrease
the content scale while
dragging down will increase
the content scale.

16. New Sensors
 KitKat introduces platform
support for two new composite
sensors – a step detector and a
step counter.
 A growing number of mobile
device are expected to enable
this capability allowing
applications to take advantage
of this data.
