Vibration for Unity3d with Android native Call, with fallback to Handlheld.Vibrate()

Vibration.cs

using UnityEngine;
using System.Collections;

public static class Vibration
{

#if UNITY_ANDROID && !UNITY_EDITOR
    public static AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    public static AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
    public static AndroidJavaObject vibrator = currentActivity.Call<AndroidJavaObject>("getSystemService", "vibrator");
#else
    public static AndroidJavaClass unityPlayer;
    public static AndroidJavaObject currentActivity;
    public static AndroidJavaObject vibrator;
#endif

    public static void Vibrate()
    {
        if (isAndroid())
            vibrator.Call("vibrate");
        else
            Handheld.Vibrate();
    }


    public static void Vibrate(long milliseconds)
    {
        if (isAndroid())
            vibrator.Call("vibrate", milliseconds);
        else
            Handheld.Vibrate();
    }

    public static void Vibrate(long[] pattern, int repeat)
    {
        if (isAndroid())
            vibrator.Call("vibrate", pattern, repeat);
        else
            Handheld.Vibrate();
    }

    public static bool HasVibrator()
    {
        return isAndroid();
    }

    public static void Cancel()
    {
        if (isAndroid())
            vibrator.Call("cancel");
    }

    private static bool isAndroid()
    {
#if UNITY_ANDROID && !UNITY_EDITOR
	return true;
#else
        return false;
#endif
    }
}

Thanks so much!

Vibration.Vibrate ( ͡° ͜ʖ ͡°));
Thank you for this, works great!

Works perfect, but i see that the calls are deprecated from API level 26. Any idea how to switch this for using VibrationEffect object?
I tried doing something like this, but its crashing on the first line:

var jo = new AndroidJavaClass("android.os.VibrationEffect");  // "core.java.android.os.VibrationEffect" is crashing too
var effect = jo.CallStatic<object>("createOneShot", milliseconds, 255);
vibrator.Call("vibrate", effect);

would also like to know the above!

(I would also like to note that this code won't run without the Vibrate permission, which Unity adds automatically when you have Handheld.Vibrate(); somewhere in your code, even when you don't use it.)

(I would ALSO like to note that simply entering plain numbers in the 'duration' field will cast them to INT while the vibration functions require them to be LONG values!)

THANK YOUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!!

I got VibrationEffect working like this:

AndroidJavaObject vibrationEffect = vibrationEffectClass.CallStatic<AndroidJavaObject>(function, args);
vibrator.Call("vibrate", vibrationEffect);

I made my own gist that works with API level 26 here.

Some license? Or free use?
App crashes for Unity 2017.1.1f1. Someone can confirm?
Handheld.Vibrate(); still working.

The implementation of HasVibrator is wrong. The best way to do that would probably be this:
return vibrator.Call<bool>("hasVibrator");

Thanks a Lot! (y)

Thanks it's working

This doesn't seem to be working for me. I get the following error when running:
Vibration' is missing the class attribute 'ExtensionOfNativeClass'!

I changed the class name from Vibration-->Vibration1 and that got rid of the error. But when calling Vibration1.Vibrate() the console prints iPhoneUtils.Vibrate() implying it's using Handheld.Vibrate() which isn't working for Android.

(I'm using Unity 2018.3.0 and testing w/ UnityRemote 5)

Edit: found out that debugging in UnityRemote does not support vibrations... that's probably the crux of it. When building, Handheld.Vibrate() worked

This doesn't seem to be working for me either. My application crashes on start, but no notable logs reveal the cause of the crash in logcat.

I'm using Unity 2019.2.9f1, with my minumum API level set to 25, and Mono and .NET 2.0.

Has anyone figured out why this causes it to crash?

Thank you! Works great on Unity 2019.2.8f1, Android 9.
Vibration.Vibrate(100) works like a charm.

Hi all! I've made a drastically improved version.

Script automatically detects Api Level. Checks if Amplitude control (API >= 26) is available. Also supports Predefined Effects (API >= 29).
If API is < 26, legacy functions are used (old api).

Code is available here: github gist link

it worked from the first try
<3<3<3<3<3<3<3<3<3
thank you @aVolpe

Hi. Here made an app based on the script created by ruzrobert above. For dev out there who want to test and tweak how vibration should feel on devices. Available only Android. Can download via Play Store: https://play.google.com/store/apps/details?id=com.maplerr.TestVibration .

Appreciate the code!

Vibration' is missing the class attribute 'ExtensionOfNativeClass'!

I deleted the "static" from "public static class" and added after "class" ": MonoBehaviour"

from
public static class Vibration
to
public class Vibration : MonoBehaviour

Thanks for good class.

in unity2019.4.10f1,

get error c# exception:UnityEngine.AndroidJavaException: java.lang.NoSuchMethodError: no non-static method with name='vibrate' signature='()V' in class Landroid.os.SystemVibrator;

change vibrator.Call("vibrate"); to vibrator.Call("vibrate" ,100); may fix it

didn't work with Vibration.vibrate(x) but it does with Vibration1.vibrate(x). didn't change the script Vibration.cs. The mystery of informatics ...
Other than that works perfect! thank you!!!

Great code. Worrks well in Unity 2020.1.17f1. Thanks! Be blessed!

Thank you for this, everything works great!
Unity 2020.3.2f1 Personal
Vibration.Vibrate(100);

'Vibration' is missing the class attribute 'ExtensionOfNativeClass'!
how to Solve this error.......
Unity 2020.3.17f1

Thank you😊

Doesn't expect this still work in 2022.
You're a hero

@SamKyada , read the reply by @agustinaA-Lopez

meanwhile 2023, Android14, copy, paste, works like a charm.
Thanks @aVolpe , you're the man...
