[FIXED] How to check if a user is logged in via Facebook in Firebase Auth

Issue

I am trying to determine whether the current user is authenticated in the app via Facebook login or not. I want that because if a user is authenticated via facebook than the signOut() should process

        LoginManager.getInstance().logOut();

but if it is authenticated via email than simple

auth.signOut();

my cuurent code is

//sign out method
public void signOut() {

    if(auth.getCurrentUser().getProviderId().equals("facebook.com")) {
        LoginManager.getInstance().logOut();
        auth.signOut();
    }
    else {
        auth.signOut();
    }
}

Solution

This is how you can do it:

if (firebaseUser != null) {
    for (UserInfo userInfo : firebaseUser.getProviderData()) {
        if (userInfo.getProviderId().equals("facebook.com")) {
            Log.d("TAG", "User is signed in with Facebook");
        }
    }
}
