How to make a user sign out in Firebase?

Question

I am making a simple authentication app in Android using Firebase authentication. Till now I am successful in signing the user in, however the issue is that the user remains

Answer 1

This one just signs you out from the current application .

if you are using a fragment do this

AuthUI.getInstance().signOut(getActivity());

if you are using an activity do this

AuthUI.getInstance().signOut(getApplicationContext);

cheers!
