我正在尝试在Android中使用WebRtc实施QuickBlox。在本教程之后，我完成了以下编码。我面临以下问题。
我不这么认为我的电话是从用户A转到用户B.
我没有收到有关来电的通知（可能是因为来电根本没有来）。
当我点击接受按钮时，我收到以下错误。
E / AndroidRuntime（11413）：致命异常：Thread-37793 E / AndroidRuntime（11413）：处理：com.example.testqb，PID：11413 E / AndroidRuntime（11413）：java.lang.NullPointerException：尝试调用虚方法'void com.quickblox.videochat.model.listeners.OnQBVideoChatListener.runOnVideoChatStateChangeUI（com.quickblox.videochat.model.objects.CallState，com.quickblox。 videochat.model.objects.VideoChatConfig）'对空对象引用 E / AndroidRuntime（11413）：at com.quickblox.videochat.core.objects.XMPPConnectionClient $ CallingRunnable.sendNotAnsweredCallback（XMPPConnectionClient.java:173） E / AndroidRuntime（11413）：at com.quickblox.videochat.core.objects.XMPPConnectionClient $ CallingRunnable.run（XMPPConnectionClient.java:158） E / AndroidRuntime（11413）：在java.lang.Thread.run（Thread.java:818）
我的完整代码如下：
我使用A按钮登录电话login1，使用B按钮登录login2。我的完整代码如下。
