 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?
