Android FirebaseAuth getCurrentUser() returns user after fresh install/build

问题

I implemented an auto-login on my app's start, if the user signed in before and did not log-out. I do this via FirebaseAuth.getInstance().getCurrentUser()

Now I build the debug-apk and install this on my physical Android phone. getCurrentUser() returns the last user I used on the Android emulator. I really don't want this to happen..

Has anyone an idea how to prevent this ? Or why is FirebaseAuth doing this ?

Thanks!

So it turned out, that FirebaseAuth took the signed in Google account from my Android device. I removed it in the settings, and getCurrentUser() returned null
