Android Firebase - setPersistenceEnabled(true) crashing the app

Question

So I was just trying out Firebase to update Toolbar label of activities from realtime database. I am getting the following error:

12-21 00:25:19.890 10295-10295/

This part mFirebaseInstance.setPersistenceEnabled(true); should be just in first Activity. It's shouldn't be called more than once.

Better solution would be to put that line in onCreate method of your Application class. You can read more about it here.
