Before releasing r2.15.0, we had a regression that crashed
PlaybackStatsListener. A change in the AnalyticsCollector made
it to send an additional AnalyticsListener.onEvents() callback after
calling Player.release() and AnalyticsListener.onEvents() appeared
to arrive with event times that were not monotonically increasing.
The AnalyticsListener.onEvents() callback that contained
AnalyticsListener.EVENT_PLAYER_RELEASED was called with a timestamp that
was smaller than event times of previously AnalyticsListener.onEvents()
calls.
A first fix changed the order of events being forwarded to
AnalyticsListener. Upon calling Player.release(), the AnalyticsCollector
would call AnalyticsListener.onPlayerReleased() and its associated
AnalyticsListener.onEvents() on the same stack call. This fix maintained
that event times are monotonically increasing, but made
AnalyticsListener.onPlayerReleased() be called earlier.
This change:
- Further changes AnalyticsCollector to ensure that
AnalyticsListener.onPlayerReleased() and its related
AnalyticsListener.onEvents() are the last callbacks to be called,
and the associated timestamp is bigger than previously reported
event times.
- Adds an instrumentation test to guard against the regression.
