我正在尝试使用以下方法查找网络中的所有服务：

mNsdManager.discoverServices(
            SERVICE_TYPE, NsdManager.PROTOCOL_DNS_SD, mDiscoveryListener);

但您必须定义 SERVICE_TYPE 例如：

public static final String SERVICE_TYPE = "_http._tcp.";

所以它会发现所有使用 tcp 的 http 服务，但它不会同时发现 https 服务或任何其他类型的服务

我如何设置所有这些以使用 tcp 查找任何服务？

先感谢您。

我在用

private static final String SERVICE_TYPE = "_services._dns-sd._udp";

这给了我局域网上所有可用服务的列表：
