[Guide] Haptic Feedback on Android with no Plugin

Hi!

So it took me 4 hours to figure out Haptic Feedback on Android without a plugin (which would be easly made, but I just didn't want to).
Keep in mind that this is just Haptic Feedback and not a fully functional vibrator!
I would be happy if someone could post other, non-plugin Haptic Feedback solutions.
I post this here since I think this is not Asset worthy and to see other, maybe better solutions.

The advantages of my method are:
-No need for vibration permission and thiswhile no custom AndroidManifest needed
-If the user disables Haptic Feedback on his device in general, there is no Haptic Feedback here, too

You would just call AndroidManager.HapticFeedback();

​

Code (CSharp):

1. using UnityEngine;
2. public class AndroidManager : MonoBehaviour
3. {
4. private class HapticFeedbackManager
5.     {
6.     #if UNITY_ANDROID && !UNITY_EDITOR
7.         private int HapticFeedbackConstantsKey;
8.         private AndroidJavaObject UnityPlayer;
9.     #endif
10.  
11.         public HapticFeedbackManager(){
12.             #if UNITY_ANDROID && !UNITY_EDITOR
13.             HapticFeedbackConstantsKey=new AndroidJavaClass("android.view.HapticFeedbackConstants").GetStatic<int>("VIRTUAL_KEY");
14.             UnityPlayer=new AndroidJavaClass ("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity").Get<AndroidJavaObject>("mUnityPlayer");
15.             //Alternative way to get the UnityPlayer:
16.             //int content=new AndroidJavaClass("android.R$id").GetStatic<int>("content");
17.             //new AndroidJavaClass ("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity").Call<AndroidJavaObject>("findViewById",content).Call<AndroidJavaObject>("getChildAt",0);
18.             #endif
19.         }
20.  
21.         public bool Execute(){
22.             #if UNITY_ANDROID && !UNITY_EDITOR
23.             return UnityPlayer.Call<bool> ("performHapticFeedback",HapticFeedbackConstantsKey);
24.             #endif
25.             return false;
26.         }
27.     }
28.  
29.     //Cache the Manager for performance
30.     private static HapticFeedbackManager mHapticFeedbackManager;
31.  
32.     public static bool HapticFeedback(){
33.         if (mHapticFeedbackManager == null) {
34.             mHapticFeedbackManager = new HapticFeedbackManager ();
35.         }
36.         return mHapticFeedbackManager.Execute ();
37.     }
38. }

 

Just found this and want to say thank you.

 

Thanks, helped a bunch!

 

how do i control the intensity of the haptic feedback

 

This is great and saved me a lot of time - thanks!!

 

Wow!! Thanks very much you are fantastic!!

 

Not working for me, Used your code and called AndroidManager.HapticFeedback(); whenever colliding with something but nothing seems to work any idea what i am doin wrong?

 

Came back here to say Handheld.Vibrate() now exists so no one goes looking for plugins and support for different device types like we did.

 

Thank You so much man
