Question

这是我从Android的Peerconnection叮当库获得的统计报告信息。

我希望在UI上显示一个指示器，以便在可能的情况下根据此报告向用户显示当前通话质量。

我不确定如何确定通话质量是好还是坏

我建议先向用户显示基本统计信息，例如C:\Project\________android\src\plugin\google\maps\CordovaGoogleMaps.java:115: error: cannot access zzo int checkGooglePlayServices = GooglePlayServicesUtil.isGooglePlayServicesAvailable(activity); ^ class file for com.google.android.gms.common.zzo not found C:\Project\---------\android\src\plugin\google\maps\CordovaGoogleMaps.java:508: error: cannot access zzbck locationRequest = LocationRequest.create()，Packet loss %，如果可能的话，请提供网络信号强度。每两秒钟计算一次。

参考：

Chromes Webrtc统计信息：chrome：// webrtc-internals

信号强度：How to detect internet speed in JavaScript?

数据包丢失：Math.round（（totalPacketLost / totalPacketSent）* 1000）;

如何确定WebRTC通话的质量
