Question

我正在使用实时协议进行语音通话android应用程序。我看到了有关android.net.rtp的Android开发文档，并编写了一些代码。我想使用Firebase来为远程主机的android设备Ip和我的android设备Ip交换Ip地址。然后，将这些IP地址放在“ rtpstream”中，但是它不起作用。因此，我检查了IP地址，然后发现每个设备的IP地址已实时更改。我的问题是我该如何设置这些IP地址，因为应用程序正常工作，在任何情况下都不会更改。

我找不到有关android.net.rtp的足够实践，所以我不确定我写的接收片段是否正确。我也想知道如何设置远程主机IP和设备的IP。我必须将这些IP地址设置为静态吗？远程设备和我的设备如何交换其IP地址？
