This document describes how to assess the current network conditions.
When you have a video call on WeChat under poor network conditions (for example, when you are in an elevator), WeChat displays a message indicating the current network quality is poor. This document describes how to use TRTC to implement a similar interaction in your own application.

Call Guide
TRTC provides the onNetworkQuality callback to report the current network quality once every two seconds. It contains two parameters: localQuality and remoteQuality.
localQuality indicates your current network quality, which has six levels: Excellent, Good, Poor, Bad, VeryBad, and Down.
remoteQuality is an array indicating the network quality of remote users. In this array, each element represents the network quality of a remote user.
Quality
Name
Description
0
Unknown
Unknown
1
Excellent
The current network is excellent.
2
Good
The current network is good.
3
Poor
The current network is fine.
4
Bad
The current network is poor, and there may be obvious stuttering and delay.
5
VeryBad
The current network is very poor, and TRTC can merely sustain the connection but cannot guarantee the communication quality.
6
Down
The current network cannot meet the minimum requirements of TRTC, and it is impossible to have a normal audio/video call.
You only need to listen for onNetworkQuality of TRTC and display the corresponding prompt on the UI.
