KitKat
Android 4.4 (code-nameKitKat) was released onOctober 31.
The android market hasoften suffered fromfragmentation as eachvendor was left to implementits own skin for Android. WithKitKat we are perhapsseeing the start of a core setof UI guidelines for themobile OS.
The following is a summaryof some of the key designchanges introduced withKitKat that should beconsidered when designingmodern Domino applications.
Android Market Share
Strategy Analytics estimatesthat in the 3rd quarter of 2013Android devices accountedfor 81% of global shipmentsfor smart phones.
While 200 million devicesupgraded to iOS 7 in the first5 days, KitKat is likely to seea much slower uptake withinitial availability limited tothe Google’s own Nexus 5.
Clearly we need to keep aclose eye on everything thatAndroid does as it slowlytakes a stranglehold on thesmart phone market and itsusers set expectations formobile application design.

Android kitkat 4.4 - What is
new in Android Update ?
Branding Color
As with iOS7, we see a move fromthe familiar blue of the Android holocolor scheme to a more neutralgrey.
This change is designed to allowapplications a greater choice ofcolor schemes that will not clashwith 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.
Full Screen
Android KitKat has improvedsupport for lettingapplications use the entirescreen.
The Lean Back approach isused when the user will haveminimal interaction with thecontent. A simple touchanywhere on the content willcause the bars to reappear.
A new Immersive approachis used when a higher levelof interaction is expected. Aswipe from the edge willcause a bar in that locationto reappear.
Translucent Bars
Similar to iOS 7 we see amove to continuously displaymore content from theapplication through the use oftranslucent system, action,and navigation bars.
Note: The use of translucentbars are an option forapplications, not arequirement.
Gestures
The double touch gesturehas now been formallydefined to scale up thetargeted area to fill thescreen.
A new double touch draggesture operates similar topinch zoom gestures.Dragging up will decreasethe content scale whiledragging down will increasethe content scale.
New Sensors
KitKat introduces platformsupport for two new compositesensors – a step detector and astep counter.
A growing number of mobiledevice are expected to enablethis capability allowingapplications to take advantageof this data.
