EventListener

Note: Event is Serializable for convenience but we currently make no guarantee that the Serialization is backward / forward compatible across LeakCanary versions, so plan accordingly. This is convenient for passing events around processes, and shouldn't be used to store them.

onEvent is always called from the thread the events are emitted from, which is documented for each event. This enables you to potentially block a chain of events, waiting for some pre work to be done.
