Agora Releases Version 3.1.2

October 7, 2020 By Jonathan Fotland In Developer

Version 3.1.2 of the Agora SDK was released on September 10, 2020.

User Experience Improvements

iOS 14 introduced a system prompt pop-up when an app attempts to find local network devices. This prompt was triggered by the local network quality report. To prevent this behavior, the gatewayRtt parameter in the reportRtcStats callback is now disabled by default. You should no longer use gatewayRtt to obtain the round-trip delay between the client and the local router.

If you wish to enable the gatewayRtt parameter, please contact Agora technical support at support @agora.io.

If you are working with iOS 14 devices, Agora recommends you update to version 3.1.2. If your implementation requires adding support for round-trip delay, Agora recommends you add a description for Privacy — Local Network Usage Description to explain to the user why this information is being accessed. Additionally, be aware that if the user denies this permission, gatewayRtt will always return -1, and your code should account for this.
