我正在尝试向智能卡发送命令.我使用Gemalto IDBridge CT30(PC TWIN阅读器)和通过USB连接到Android设备的IDBridge K30.

我尝试通过USB发送SELECT APDU命令:

boolean claim = openedConnection.claimInterface(usbInterface, true);
byte[] data = new byte[]{
        (byte) 0x00, (byte) 0xA4, (byte) 0x04, (byte) 0x0C,
        (byte) 0x07, (byte) 0xA0, (byte) 0x00, (byte) 0x00,
        (byte) 0x01, (byte) 0x18, (byte) 0x45, (byte) 0x4E};

之后我收到了答案:

final int dataTransferred = this.openedConnection.bulkTransfer(endPointOut, data, data.length, TIMEOUT_MS);
if(!(dataTransferred == 0 || dataTransferred == data.length)) {
    throw new Exception("Error durring sending command [" + dataTransferred + " ; " + data.length + "]"); //$NON-NLS-1$ …
