Hi tapLinx support, I use your code implementation, but I have the same problem and the same exception.
I noticed that you are using the taplinx library version 1.8. I have the 1.7 version and there isn't the method libname.getTapLinxVersion(), where can I download the 1.8 version? Another problem is the CardType cardType=m_libInstance.getCardType(intent); it return unknown I can't assign this variable, if I do evaluate on this m_libInstance.getCardType(intent) it return NTAG424Tag Tumper.
In my code, that is like your, my byFCI is null, isoSelectApplicationByDFName(NTAG424DNATT_APP_NAME) and return always null.
I have the same problem as before, on AuthenticateEV2First the application return 911C, and if i try to do isoSelectApplicationByDFID(ID) with ID method that i'd posted earlier return exception 6A82. I post the code that I using now.
Could be the 1.7 library the problem? Where can I find the 1.8 library?
Help me, please it's for my degree project.
Thank you in advice for your help.
