Hi,everyone! I have learn nfc phone how to read different card. For the Mifare Classic, i have a problem for value block. For the MifareClassic api , i can read and write with nfc phone. But i can't decrement,increment,restore, transfer. The api is :decrement(int blockIndex, int value) "Decrement a value block, storing the result in the temporary block on the tag." How should I do in the program? I know value block have a fixed data format in the specification.Had the api take blockindex converted into value block automatically??Who can provide a code for my reference?
