setProvisionalAwareTimelineUpdateListener
Sets a listener that is invoked when the event timeline is updated. The listener receives the updated events. An update can be triggered by the start of a new event, and the update or end of an existing one. Every invocation of the listener will deliver an event that has a lastUpdateTime that is equal to or greater than the previously delivered event's lastUpdateTime.
The updates received could include provisional ones. See isProvisional to learn more about what a provisional event is.
You can use this method along with getTimelineUpdates to stay up to date with the latest events in the timeline. For example, to make sure you don't miss out on timeline updates, you can first set an update listener using this method, then follow up by calling getTimelineUpdates to query for potential updates since the last update you received.
Parameters
The listener to receive event timeline updates, or null to remove the previously set listener.
Throws
if the SDK is not initialized
