Please can you provide an unobfuscated stack trace so we can understand exactly what line is throwing the NPE? I couldn't spot any WeakReference usages near to DefaultAnalyticsCollector in the ExoPlayer code - so I wonder if this could be coming from an implementation of AnalyticsListener.onTimelineChanged in your app?
