Hi, I'm back to ask a little questions about nfc.
I have a NFC tag reader and Google Nexus S. I want to create an app for Google Nexus S that emulates a nfc tag. 1) Where I could find example code in java? Because there isn't no info about this. I think it could be similar to: -Creating the nfc tag to emulate (give him a value) -Activating emulation of nfc tag -Wait for a NFC tag reader signal (NFC tag reader sends a message telling to the phone, msg received?) -Desactivating emulation of nfc tag My NFC reader is CPR40.30-USB (More info: http://www.toptunniste.fi/topshop/product_details.php?p=264&c=76). 2) Should I create new functions to use it and create a new SDK? Did you know any tutorial to modify SDK and create other functions? Or should I create it in NDK using native code? 3) The steps to enable Google Nexus S Smart Card functionality will be: -Unlock the boot loader -Root Google Nexus S -Create the modified rom (with the diff you posted in http://groups.google.com/group/android-developers/browse_thread/thread/d5fc35a9f16aa467/dec4843abd73d9e9%3Flnk%3Dgst%26q%3Dsecure%2Belement%2Bdiff%2527s%23dec4843abd73d9e9 ). -Load the new rom. -Install the app 4) Do you know when all nfc funcionality will be available in the official SDK? Thanks!
