WebRTC客户端在opensslidentity上失败为webrtc制作证书

Question

我正在使用WebRTC演示应用程序开发用于Android的webrtc客户端 虽然我使用org.webrtc库来开发客户端，但在运行自己的客户端时遇到了问题。

当我运行我的客户端时，下面是我得到的logcat（完整logcat的一部分）

当我运行WebRTC演示应用程序时，我得到以下logcat：

我的客户正在崩溃点

但WebRTC演示运行正常 我观察到的差异如下：
我的客户无法从logcat中看到opensslidentity certificate for WebRTC。
我的客户被困在

2-10 18:32:49.260 7669-9530/org.appspot.apprtc I/libjingle: (opensslidentity.cc:47): Making key pair

但是，演示应用程序能够做到这一点。


我想知道为什么我的客户无法出示证书？

Answer 1

当我不使用Ice Server时，发生了这个问题。将Ice Server传递给PeerConnection后，该应用程序正常运行
