TRTCLiveRoom APIs (Android)
TRTCLiveRoom includes the following features which are based on Tencent Real-Time Communication (TRTC) and Tencent Cloud Chat.A user can create a room and start live streaming, or enter a room as an audience member.
The anchor can co-anchor with audience members in the room.
Anchors in two rooms can compete and interact with each other.
All users can send text and custom messages. Custom messages can be used to send on-screen comments, give likes, and send gifts.
Note
TRTCLiveRoom is an open-source class depending on two closed-source Tencent Cloud SDKs. For the specific implementation process, please see Interactive Live Video Streaming (Android).The TRTC SDK is used as a low-latency audio chat component.
The
AVChatRoom feature of the Chat SDK is used to implement chat rooms. The attribute APIs of Chat are used to store room information such as the seat list, and invitation signaling is used to send requests to speak or invite others to speak.
