• Memory optimizations also for lower end devices
• Faster multitasking

bluetooth/Wi-Fi
• To print generic content, output pdf format from your data, using
PdfDocument
• android.print package, PrintDocumentAdapter,

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)
