我正在使用原生 android WebRTC 开发视频聊天应用程序。我正在使用公共 google STUN 服务器和 XIRRYS STUN 和 TURN 服务器。

我的问题是连接成功率很低！

连接成功率如下：

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

在所有情况下，offer、answer 和 Candidate 消息都很好地通过信令服务器运行，但正如我所说，在任何情况下连接都失败了。

我试图检查 SDP 和候选人信息，但在那里我看不到任何问题：

这是 LOGCAT 失败的一个示例：

我该怎么做才能提高成功连接率？

经过多次检查和多次测试和连接尝试......经过如此多的日志和显示，我能够解决问题并实现 100% 的成功连接率，无论设备的网络如何！

如果您要问，这是非常愚蠢的问题（在这种情况下总是如此），我在信令服务器端缺少 UTF8 编码，因此某些数据消息已损坏！

修复后，我获得了 100% 的成功连接率！

tfrysinger，对于你的问题，是的，我在 XirSys 的聊天中花了一些时间来支持他们，但他们无法帮助我。

无论如何，我的电子邮件地址是 zionrevi@gmail.com。

谢谢，锡安
