Why callback functions are not called in Android Facebook Login?

Question

There is no any Log.w is appear in Logcat after logged in, why?

This Code inside onCreateView in LoginFragment

CallbackManager callbackManager = CallbackManager.Factory.create();
fragmentLoginBinding.fragmentLoginFacebookLoginOriginal.setFragment(this);
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback < LoginResult > () {
    @Override
    public void onSuccess(LoginResult loginResult) {
        Log.w(Tag, "S");
    }

    @Override
    public void onCancel() {
        Log.w(Tag, "C");
    }

    @Override
    public void onError(@NonNull FacebookException e) {
        Log.w(Tag, "E - " + e.getMessage());
    }
});

Probably you're missing onActivityResult hook:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}
