HelloPicking not working on Android

I create project from hello piking tutorial

createNPC(50,0,50);
 rootNode.attachChild(shootables);

    private void createNPC(float x,float y,float z) {
        Spatial model = assetManager.loadModel("assets/Models/test.glb");
        String id = getRandomString();
       
        model.setName( id);
        SphereCollisionShape sphereShape = new SphereCollisionShape(2.0f);
        CharacterControl myThing_phys = new CharacterControl( sphereShape , 1.2f );
        model.addControl(myThing_phys);
        
        
        bulletAppState.getPhysicsSpace().add(model);
        model.addControl(new EnemyControl(this)); 
        myThing_phys.setPhysicsLocation(new Vector3f(x,y,z));

        
        shootables.attachChild(model);
        
    }

 public void shoot(){
        if(nextShoot< Instant.now().getEpochSecond()){
            if(cartridges > 0){
                cartridges = cartridges - 3;
                shootSound.play();
                CollisionResults results = new CollisionResults();
                Ray ray = new Ray(cam.getLocation(), cam.getDirection());
                shootables.collideWith(ray, results);
                if (results.size() > 0){
                    Vector3f pt = results.getCollision(0).getContactPoint();
                    Spatial npcSpatial = (Spatial)results.getCollision(0).getGeometry().getParent().getParent().getParent();

                    EnemyControl npcControl = npcSpatial.getControl(EnemyControl.class);
                    if(npcControl != null){
                        npcControl.shuted();
                    }
                }
                nextShoot = Instant.now().getEpochSecond() + 1;
            }else{
                clickSound.play();
            }
        }
  }

npc die after 3 piking

and not working on android
only works from a short distance

Start by reproducing the picking behavior on Android and desktop using the HelloPicking tutorial. Inspect the createNPC and shoot code, especially the ray collision and parent traversal used to find the NPC. Done means picking NPCs works from the expected distance on Android as it does on desktop.
