Feedback Haptic feedback class

Hello everyone,
So, I made this class in unity for haptic feedback but unfortunately as I figured out my device does not support neither the Vibrator class nor the HapticFeedback (both Vibrator.hasVibrator and View.isHapticFeedbackEnabled return false). Can someone tell me if the code below works with a device that has either vibration or haptic?

Here is the code:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class AndroidHapticFeedback
4. {
5.     //VibrationEffect Constants
6.     public const int EFFECT_CLICK           =  0;   //api 29
7.     public const int EFFECT_DOUBLE_CLICK    =  1;   //api 29
8.     public const int EFFECT_TICK            =  2;   //api 29
9.     public const int EFFECT_HEAVY_CLICK     =  5;   //api 29
10.  
11.     //HapticFeedback Constants
12.     public const int LONG_PRESS             = 0;   //api 3
13.     public const int VIRTUAL_KEY            = 1;   //api 5
14.     public const int KEYBOARD_TAP           = 3;   //api 8
15.     public const int KEYBOARD_PRESS         = 3;   //api 27
16.     public const int CLOCK_TICK             = 4;   //api 21
17.     public const int CONTEXT_CLICK          = 6;   //api 23
18.     public const int KEYBOARD_RELEASE       = 7;   //api 27
19.     public const int VIRTUAL_KEY_RELEASE    = 8;   //api 27
20.  
21. #if UNITY_ANDROID
22.     private int apiLevel;
23.     private bool hasVibrator;
24.     private bool hasHapticFeedback;
25.     private AndroidJavaClass vibratorClass;
26.     private AndroidJavaClass vibrationEffectClass;
27.     private AndroidJavaClass viewClass;
28.     //private AndroidJavaClass unityActivity;
29. #endif
30.     public AndroidHapticFeedback()
31.     {
32. #if UNITY_ANDROID
33.         apiLevel = GetSDKInt();
34.  
35.         vibratorClass = new AndroidJavaClass("android.os.Vibrator");
36.         hasVibrator = vibratorClass.Call<bool>("hasVibrator");
37.         if (hasVibrator)
38.         {
39.             vibrationEffectClass = new AndroidJavaClass("android.os.VibrationEffect");
40.         }
41.         else
42.         {
43.             viewClass = new AndroidJavaClass("android.view.View");
44.             hasHapticFeedback = viewClass.Call<bool>("isHapticFeedbackEnabled");
45.             Toast.ShowToast("Has haptic: " + hasHapticFeedback.ToString());
46.         }
47.  
48.         //unityActivity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
49. #endif
50.     }
51.  
52. #if UNITY_ANDROID
53.     private int GetSDKInt()
54.     {
55.         var version = new AndroidJavaClass("android.os.Build$VERSION");
56.         return version.GetStatic<int>("SDK_INT");
57.     }
58. #endif
59.  
60.     /// <summary>
61.     /// Gives the desired haptic feedback / vibration pattern if the device supports it

68.         if (hasVibrator && apiLevel >= 29) // vibration effects are only supported with api level 29 and above (android 10)
69.         {
70.             vibratorClass.Call("vibrate", vibrationEffectClass.CallStatic<AndroidJavaClass>("createPredefined", vibrationEffect));
71.         }
72.         else if(hasHapticFeedback && apiLevel >= 3)
73.         {
74.             viewClass.Call<bool>("performHapticFeedback", vibrationEffect);
75.         }
