Package amlib.ccid Description

It provides classes to communicating with AlcorMicro smart card reader on Android 3.1 or above.

To create Reader object
Object HardwareInterface is needed when constructing a class Reader,
you should create and initial 'HardwareInterface myDev' before create Reader

  Reader myReader

  try {
      mReader = new Reader(myDev);                      
  }
  catch(Exception e){
       e.printStackTrace();
  }
 

To connect to Reader object

  int status;
  try {
       status = mReader.connect();
   }
   catch(Exception e){
       e.printStackTrace();
  }
  

To power on/power off ICC

  int status;
  try {
       status = mReader.setPower(Reader.CCID_POWERON );
   }
   catch(Exception e){
       e.printStackTrace();
  }
  try {
       status = mReader.setPower(Reader.CCID_POWEROFF );
   }
   catch(Exception e){
       e.printStackTrace();
  }
  

Transmitting APDU

  byte pSendAPDU[] = new byte[] {(byte) 0xA0, (byte) 0xA4, 0x00, 0x00, 0x02, 0x3F, 0x00};
  byte pRxBuff[] = new byte [128];
  int pRxLen[] = new int[1];
  int status;
  try{
      status = mReader.transmit(pSendAPDU, pSendAPDU.legnth, pRxBuff, pRxLen);
      if (status != error.READER_SUCCESSFUL){
            //shows error
      }
      else{
                 for (int i=0;i<pRxLen[0]; i++){
                      Log.d(TAG, "Received byte["+ i+ "]=0x"+ Integer.toHexString(pRxBuff[i]));
                 }
      }
  }
  catch (Exception e){
           e.printStackTrace();
  }
 

Send Escape

  byte pData[] = new byte[] {CMD_VENDOR_OP_CODE, VENDOR_CMD, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
  byte pRxBuff[] = new byte [128];
  int pRxLen[] = new int[1];
  int status;
  try{
      status = mReader.escape(pData, pData.legnth, pRxBuff, pRxLen);
      if (status != error.READER_SUCCESSFUL){
                //shows error
           }
           else{
            for (int i=0;i<pRxLen[0]; i++){
                Log.d(TAG, "Received byte["+ i+ "]=0x"+ Integer.toHexString(pRxBuff[i]));
             }
       }
  }
 catch (Exception e){
           e.printStackTrace();
 }
 

To get ATR

  String atr;
  byte []atrArray = new byte[64];
  try {
      atr = mReader.getAtrString();
      atrArray = mReader.getAtr();
  }
  catch (Exception e){
           e.printStackTrace();
  }
 

To get Card Status

 byte pCardStatus[] = new byte[1];
 int status;
 try {
       status = mReader.getCardStatus(pCardStatus);
   }
   catch(Exception e){
       e.printStackTrace();
   }
   if (status == error.READER_SUCCESSFUL){
       //shows card status  
   }
   

To get current protcol

 
    byte []proto = new byte[1];
    try {
        status = mReader.getProtocol(proto);
    }
    catch(Exception e){
        e.printStackTrace();
    }

    if (status == error.READER_SUCCESSFUL && proto[0] == Reader.CCID_PROTOCOL_T0){
        //do something
    }
 

To get SN in EEPROM

 
    byte pLen[] = new byte[1];
    byte []pSN;
    pLen[0] = 32;
    pSN = new byte[pLen[0]];
    try {
        status = mReader.getSN(pSN, pLen);
    }
    catch(Exception e){
        e.printStackTrace();
    }
    if (status == error.READER_SUCCESSFUL){
        //shows the SN   
    }

To close Reader

  try {
        if (myDev.Close()){
             //shows error
        }
    }
    catch(Exception e){
        e.printStackTrace();
    }
