通話状態のモニタリング

This article explains the usage of TUICallKit call status callback. You can monitor call events (e.g., start, end, member join, and leave) via call callback registration.
Note:
On the Android platform, when setting TUICallObserver to listen for callbacks, ensure that the class hosting the callback will not be destroyed. For example, it is not recommended to add the observer in LoginActivity, as when LoginActivity is destroyed, the callback will also be destroyed; it is suggested to observe in the application's Application class or the main application interface.
Call Status Callback
Detect key state changes throughout the call lifecycle.

Track individual actions or status changes of call participants, primarily used for real-time display of member dynamics (such as join, leave, reject).
