无法在Android中使用QuickBlox WebRtc接收和接受视频通话

Question

我正在尝试使用Android中的QuickBlox实现WebRtc 。 在学习完本教程之后，我完成了以下编码。 我面临以下问题。

1. 我认为我的通话是从用户A转到用户B。

2. 我没有收到来电通知（可能是因为根本没有来电）。

3. 当我单击接受按钮时，出现以下错误。

E / AndroidRuntime（11413）：致命例外：Thread-37793 E / AndroidRuntime（11413）：进程：com.example.testqb，PID：11413 E / AndroidRuntime（11413）：java.lang.NullPointerException：尝试调用虚拟方法'在空对象引用E / AndroidRuntime（11413）上将com.quickblox.videochat.model.listeners.OnQBVideoChatListener.runOnVideoChatStateChangeUI（com.quickblox.videochat.model.objects.CallState，com.quickblox.videochat.model.objects.VideoChatConfig）无效）：在com.quickblox.videochat.core.objects.XMPPConnectionClient $ CallingRunnable.sendNotAnsweredCallback（XMPPConnectionClient.java:173）E / AndroidRuntime（11413）：在com.quickblox.videochat.core.objects.XMPPConnectionClient $ CallingRunnable.run（X .java：158）E / AndroidRuntime（11413）：位于java.lang.Thread.run（Thread.java:818）

我的完整代码如下：

我在电话上登录A使用login1按钮， B使用login2按钮。 我的完整代码如下。

Tiny，您使用的是哪个版本的Android SDK？ Android WebRTC SDK的新版本将于8月27日至28日发布，该版本应已修复。
