MIFARE CLASSIC 卡 M1卡 android NFC 子线程读取 写入

什么手机支持MIFARE CLASSIC 卡（非接触卡 ）标签，并不是所有手机都支持的；

具体见（稍等）；

读写

原来方法，读取，每次都new 一个线程；这样读取64块，时，就有64个子线程；相当的耗内存的；
于是改写，想到了线程池；
注意比对，下面的2种写与2种读；

    /*** * @param sectorIndex : 扇区编号* @param blockInde   : 块编号* @return*/public void readData(int sectorIndex, int blockInde){new OnReadThread(sectorIndex, blockInde).start();}/**** @param sectorIndex : 扇区编号* @param blockInde   : 块编号* @return*/public void readDataFromPool(int sectorIndex, int blockInde){onRead(sectorIndex,blockInde);}/**** @param data 写入的数据* @param sectorIndex 扇区编号* @param blockInde 块编号*/public void writeDataFromPool(byte[] data, int sectorIndex, int blockInde){onWrite(data,sectorIndex,blockInde);}/*** 向标签中写入数据*/public void writeData(byte[] data, int sectorIndex, int blockInde){new OnWriteThread(data, sectorIndex, blockInde).start();}

读取卡片，写卡片，都是开启的线程池；

发现直接用for循环，主线程来读，也是很快的；不用加delay；
直接读；
有的老手机，发现，用线程池，偶尔有些失败，tag is lost；

特别注意：在写数据时，必须要先写数据块，再写密码块；
单独写密码块，不能将数据写进；还报错；
