TUIRoom (Android)

TUIRoom is based on Tencent Real-Time Communication (TRTC) and Tencent Cloud Chat. With TUIRooom:
A host can create a room, and users can enter the room ID to join the room.
Participants can share their screens with each other.
All room members can send text chat messages and custom messages.
Note:
All components of TUIKit use two basic PaaS services of Tencent Cloud, namely TRTC and Chat. When you activate TRTC, Chat and the trial edition of the Chat SDK (which supports up to 100 DAUs) will be activated automatically. For the billing details of Chat, see Pricing.
TUIRoom is an open-source class depending on two closed-source Tencent Cloud SDKs. For the specific implementation process, see Integrating TUIRoom (Android).
The TRTC SDK is used as a low-latency audio/video room component.
The Chat SDK (Android edition) is used to implement chat messages.
