问题
I'm currently working with an Android payment application using NFC.For this purpose Android application need to send and receive APDU commands to ISO/IEC 14443-4 Smart Card.
When i test my application using Galaxy S5(OS 4.4.2) , or Galaxy s3(OS 4.1.2) I'm getting 6A82
My Code flow is going like below:
1st step ->
Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
IsoDep iso = IsoDep.get(tag);
iso.connect();
2nd step ->
By using iso.transceive()..
I'm sending APDU command 0084000008 from Mobile Application to Smard Card and
receiving F5BC9C9F3A2B7C179000 as response.
3rd Step ->
using iso.isConnect() I'm checking the connection and
-> Connection available
4th Step ->
By using iso.transceive()..
sending APDU command : 903203000A1403CF549C2B7520389C
receiving : 6A82 All the time
I would be happy if anyone suggest me why I'm getting strange File not found (6A82) for this APDU command.
回答1:
after calling iso.connect() you should send select apdu first
00A40400 +
for example :
(u should convert hex to bytes first)
aid = AABBCCDD;
byte[] selectCmd = 00A4040004AABBCCDD
isoDep.transceive(command)
