[android-developers] Re: NFC Secure Element
When the card emulation is detected, the call is routed to nfc_jni_transaction_callback() of SecureElement. From here the event is posted to NfcService for example AID_SELECTED events are all posted to NfcService. I was wondering if there is way to communicate to SecureElement through this handle. If I try to open SecureElement parallel y, the call throws error that "External RF Field is detected", when this channel is open, I believe there must be a way to wait until this mode is finished and communicate back to SecureElement or use the same channel to communicate. In fact, If I view the ice-scream sandwich code, there is new event subscription APDU_RECIEVED in the secure element callback. It looks like the PICC interface is open now. Hopefully we should be able to communicate. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: NFC Secure Element
I am not sure if anybody explored NfcExecutionEnvironment class. There are APIs to communicate to secure element. I don't see any key requirement. I could listen to AID_SELECTED event from NfcService. I am trying to send data to SE. I get error that "External RF Field detected", what does this mean. Should I be waiting until the external reader sets mode or i have to initiate the NFC mode. regards malls On Feb 6, 5:51 am, "s.rawat" wrote: > Hi Nemik, > You wrote : > *Yea, that's right.

Re: [android-developers] Re: NFC Secure Element
I don't see any interface of passing the keys to open secure element in the android code. I am not sure how many people claims that you need google Keys to open SecureElement. May be I am missing something. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: NFC Secure Element
Fernando, Thanks I could create custom image with nfc enabled by using your help. Just to clarify myself, if we are connected to external reader, I should be able to directly read/write APDUs from my app right. should I be using NFCService.transceive(..) method to read/write from the external reader. regards malls On Jan 4, 6:17 am, Fernando Miguélez wrote: > Well, options are enabled in cascade.
