Hide Loading Screen In ArFragment

Question

I am new to ArCore and using ArFragment. I want to show my "menu" view when the planes are detected and hide this loading image.

I used "arFragment.getArSceneView.getScene().setOnUpdateListener". Whenever I implement my own "setOnUpdateListener",I am able to show my menu but this loading image does not hide. This image only hides automatically when I do not implement the updateListener. Here is the fragment from activity_main.xml and listener from MainActivity.java

<fragment android:name="com.google.ar.sceneform.ux.ArFragment"
    android:id="@+id/ux_fragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

        ArSceneView arSceneView =arFragment.getArSceneView();
    arSceneView.getScene().setOnUpdateListener(
            frameTime -> {
                Frame frame = arSceneView.getArFrame();
                if (frame == null) {
                    return;
                }
                if (frame.getCamera().getTrackingState() != TrackingState.TRACKING) {
                    return;
                }

                for (Plane plane : frame.getUpdatedTrackables(Plane.class)) {
                    if (plane.getTrackingState() == TrackingState.TRACKING) {
                        Log.e("********************","");
                        hsv.setVisibility(View.VISIBLE);
                    }
                }
            });

You can work around having the plane discovery view always show on startup by hiding the view, then setting it to null so it won't reappear. In onCreate() add:

arFragment = (ArFragment) 
        getSupportFragmentManager().findFragmentById(R.id.ux_fragment);
arFragment.getPlaneDiscoveryController().hide();
arFragment.getPlaneDiscoveryController().setInstructionView(null);
