Android WebRTC低成功连接率 _Android

登山则情满于山，观海则意溢于海。这篇文章主要讲述Android WebRTC低成功连接率相关的知识，希望能为你提供帮助。
我正在使用本地android WebRTC开发视频聊天应用程序。我正在使用公共Google STUN服务器以及XIRRYS STUN和TURN服务器。
我的问题是，成功的连接率非常低！
【Android WebRTC低成功连接率】成功连接率如下：

当我使用WIFI网络时，大约有50％的连接失败
关于90％连接失败，当我使用移动互联网时。

我试图检查SDP和候选者信息，但在那里看不到任何问题：
这是LOGCAT中的一个失败示例：

我正在使用本地android WebRTC开发视频聊天应用程序。我正在使用公共Google STUN服务器以及XIRRYS STUN和TURN服务器。我的问题是成功的连接速率非常高...
答案经过许多检查，并进行了许多测试和连接尝试。...经过如此多的日志和显示后，无论设备的网络如何，我都能够解决问题并成功实现100％的连接速率！
