Android 4.4 KitKat (API Level 19)

• Small visual changes• No more blue on black color, neutral gray for system color allowsdesigners more freedom

• More performance and battery life is never bad• Memory optimizations also for lower end devices

• Faster multitasking

• Whispers about ART vs Dalvik performance

• WebView based on Chromium (Might break older apps)

• Improvements for NFC (Host Card Emulation), Printing Api, Storage Access Framework, Bluetooth MAP (Message Access Profile), etc

28.1.2014


KitKat – color change and immersive mode

KitKat – NFC Enhancements

• Host Card Emulation

• Existing model uses card emulation with a secure element inside

device: new element does emulation by host directly without

secure element

• Secure element requires support from carriers, HCE works directly

within smart device and app

• Android device can now emulate NFC cards, allowing Android to

emulate multiple NFC cards at the same time

• Potential for payment applications, Bonus cards, Tap&Pay, etc

• NFC Reader mode

• Restricts NFC activity to just reading interesting tags

• Android can now operate as both payment terminal, and payment client (bonus card/micropayment card)
