Android HCE 服务未被识别

Question

我在创建一个简单的 HCE 应用程序时遇到问题，但当尝试执行时，我得到的只是响应 6F00，我想这是由于该服务未注册为 HCE 服务，但我似乎无法找到原因的解决方案。 ..

（请注意，我正在使用前台服务来测试是否解决了任何问题......所以任何问题都是不相关的）

谢谢！

我在2个不同的设备上进行了测试，非接触式支付选项默认未设置为任何特定服务。

尝试在前台执行服务。

Answer 1

这可能是因为根据 ISO IEC 7816-4 的“8.2.1.2 应用程序标识符”部分，您使用的 AID 值“00000000000000”是为向后兼容 ISO/IEC 7812-1 而保留的

这可能会导致问题，并且不是正确的使用值。

所有未注册的 AID 均应以“F”开头

因此尝试使用 AID“F0000000000000”作为 apduservice.xml 中的

aid-filter

值
