使用android nfc与iso 14443卡通信

我一直在尝试编写一个基本的android应用程序，它可以将APDU发送到ISO 14443卡并接收APDU的响应。我在智能卡中已经有ID为F000000A的小程序。到目前为止，我已经编写/修改了其他代码，但我知道我做了一些错误的事情，因为我的应用程序在我的手机上崩溃，因为我试图启动它。下面是我的代码，仅供参考。我的Isodep收发器在不同的类中，我的Isodep适配器也在不同的类中

ISODEP适配器：

您没有发布名为kitkat.com.example.kaudi.MainActivity的活动的任何代码。由于异常正好表明了这一点—您的类路径上没有名为MainActivity的活动—我假设您实际上想要在清单中声明kitkat.com.example.kaudi.NfcReader。

请发布代码—将代码粘贴到您的问题中，而不是链接—实际上您甚至没有链接它们。是否也发布错误跟踪？当你的应用程序崩溃时，你会发现。@MichaelRoland您好。.感谢您的回复…我已经这样做了…我以前认为它看起来太乱了：另外请注意，特别是如果你使用Java卡，但也使用许多其他智能卡，如果您尝试使用少于5字节的辅助数据，并且尝试交换根据ISO 7816-4格式不正确的APDU，您可能会遇到问题。是的……您是对的……现在我的应用程序没有崩溃……但不幸的是，我目前没有卡可以尝试……请在从运行应用程序后，我还有一个问题eclipse…如何发送后续命令..是否来自apdutool.bat？？我很感激，我不明白你的意思。您可以使用IsoDep.transceive从Android应用程序向卡发送命令。。。方法。很抱歉，但我不太明白…在构建和运行应用程序之后…是否可以添加代码并发送APDU…或者我是否在应用程序中创建一些界面，在其中键入并发送APDU…抱歉我的愚蠢…抱歉，但我无法帮你在应用程序中做出基本的设计决策。您通常会根据自己的需要进行设计。如果您需要手动键入apdu，那么您肯定需要为此设计一个UI。不过，从可用性的角度来看，让用户在手持设备卡的同时键入APDUs并不是一个好主意。
