    TRTCLiveRoom APIs (Android)

    Last updated: 2024-09-14 16:47:24
      Note：
      The TRTCLiveRoom component has been discontinued. If your business scenario requires integrating live functionality, you can use the new version of the voice chat room (including UI) called TUILiveKit.
      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
      All TUIKit components are based on two basic PaaS services of Tencent Cloud, namely TRTC and Chat. When you activate TRTC, the Chat SDK trial edition (which supports up to 100 DAUs) will be activated automatically. For Chat billing details, see Pricing.
      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.
