Under what circumstances will an app deletes Firebase Instance ID?

Question

FirebaseInstanceIdService.class clearly states that onTokenRefresh() will be called when:

App deletes Instance ID
App is restored on a new device
User uninstalls/reinstall the app
User clears app data

When and under what circumstances will an app deletes an instance ID? Is there a possibility of it happening while an app is still active (ongoing activity or service)?

The app deletes the Instance ID when you call FirebaseInstanceId.deleteInstanceId() in app:

Resets Instance ID and revokes all tokens.

And yes, you can call this method while your app is active.

but if I'm under impression that I will never have to call it manually, will my app automatically call that function? – Hendra Anggrian Mar 07 '17 at 08:18
AFAIK, no. The function will not get called if you won't explicitly call it yourself. – AL. Mar 07 '17 at 10:27
