Hi,Michael!Thanks your answer.
I need to read and write ISO 14443-4 smart card .I had used
"mTechLists = new String[][] { new String[]
{ NfcA.class.getName() } }"
"NfcA tag=NfcA.get(tagFromIntent)".How to use IsoDep? The problem with
me for a long time.
Next, What I should do? Can give me some hints?
Thank you very much!
