android - Does FirebaseMessagingService run in the background by default?

Question

Does the FirebaseMessagingService run in the background similar to how an IntentService operates?

I see that FirebaseMessagingService extents Service which does not run in the background, but I'd like to be sure whether or not I should be doing any work inside the FirebaseMessagingService asynchronously or synchronously.

Thank you

ANSWER:

FirebaseMessagingService's method onMessageReceived(RemoteMessage message) is NOT called on the main thread - so all work should be synchronously.
