I also have this problem, right now, the LogoutBtn is inside a drawer, like this:

case R.id.initiates_logout:
            if(FirebaseAuth.getInstance().getCurrentUser()!=null){
                new AlertDialog.Builder(this)
                        .setTitle("Text1")
                        .setMessage("Text2")
                        .setIcon(android.R.drawable.ic_dialog_alert)
                        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int whichButton) {
                                FirebaseAuth.getInstance().signOut();
                                LoginManager.getInstance().logOut();


                            }})
                        .setNegativeButton(android.R.string.no, null).show();
            }
            break;

And i cant select another account after the logout.

If you check the Firebase Auth Quickstart sample code, the sign-out for Google provider includes these steps.

Are you calling Auth.GoogleSignInApi.signOut() when you sign-out? So, please use this code:

private void signOut() {
    // Firebase sign out
    mAuth.signOut();

    // Google sign out
    Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
        new ResultCallback<Status>() {
            @Override
            public void onResult(@NonNull Status status) {
                //do what you want
            }
        });
}

You are using a newer version than me, I doubt they introduced a new bug. You mentioned NullPointerException earlier, so I suggest you make sure the GoogleApiClient you pass to Auth.GoogleSignInApi.getSignInIntent is not null.
