我需要在一个 android 应用程序中实现 ONVIF，直到现在我还没有取得太大的成功。我尝试使用evercam，但使用它会导致“ClassNotFoundException”。这是完整的堆栈跟踪。

有没有人有任何想法如何以不同的方式实现它？

在 android 上为 onvif 设备执行 WS-Discovery 的代码片段。确保您的 IP 摄像机已连接到本地网络。将您的本地网络广播地址提供给数据报套接字。

private void discoverWsDevices() throws SocketException {
    final int WS_DISCOVERY_PORT = 3702;
    final String WS_DISCOVERY_ADDRESS_IPv4 = "192.168.49.255";//"239.255.255.250";

    new Thread() {
        public void run() {

            final String probe = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" +
