Android WebRTC连接成功率低
Android WebRTC low success connection rate
我正在使用本机 android WebRTC 开发视频聊天应用程序。
我正在使用 public 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：
- 使用WIFI网络时连接失败率约50%
- 大约 90% 的连接失败 当我使用移动互联网时。
在所有情况下，offer、answer 和 candidates 消息都运行很好地通过信令服务器，但正如我所说，在任何情况下连接都会失败。
我尝试检查 SDP 和候选人信息，但我看不出有任何问题：
这是 LOGCAT 中的一个失败示例：

如何提高连接成功率？
经过多次检查、多次测试和连接尝试......
经过这么多的日志和显示，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！
如果你问的话，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，所以一些数据消息已损坏！
修复后，我的连接成功率达到了 100%！
tfrysinger，
对于你的问题，是的，我花了一些时间与 XirSys 一起聊天，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
我正在使用本机 android WebRTC 开发视频聊天应用程序。 我正在使用 public 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：
- 使用WIFI网络时连接失败率约50%
- 大约 90% 的连接失败 当我使用移动互联网时。
在所有情况下，offer、answer 和 candidates 消息都运行很好地通过信令服务器，但正如我所说，在任何情况下连接都会失败。
我尝试检查 SDP 和候选人信息，但我看不出有任何问题：
这是 LOGCAT 中的一个失败示例：

如何提高连接成功率？
经过多次检查、多次测试和连接尝试...... 经过这么多的日志和显示，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！
如果你问的话，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，所以一些数据消息已损坏！
修复后，我的连接成功率达到了 100%！
tfrysinger， 对于你的问题，是的，我花了一些时间与 XirSys 一起聊天，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
