Android vibrate is deprecated. How to use VibrationEffect in Android>= API 26?

I am using Android's VIBRATOR_SERVICE to give a haptic feedback for a button touch.

 ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(300);

Android Studio give me warning that method vibrate(interval) is deprecated I should use VibrationEffect for API>23.

So I usedVibrationEffect's method createOneShot which takes 2 params: interval, and amplitude.

I tried searching for it but got no clue about what to pass as amplitude, anybody got any idea about how to use it?

Update Added code

// Vibrate for 150 milliseconds
private void shakeItBaby() {
    if (Build.VERSION.SDK_INT >= 26) {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createOneShot(150,10));
    } else {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(150);
    }
}

with kotlin

private fun vibrate(){
    val vibrator = context.getSystemService(Context.VIBRATOR_SERVICE) as Vibrator
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
         vibrator.vibrate(VibrationEffect.createOneShot(200, VibrationEffect.DEFAULT_AMPLITUDE))
    } else {
         vibrator.vibrate(200)
    }
}

Amplitude is an int value. Its The strength of the vibration. This must be a value between 1 and 255, or DEFAULT_AMPLITUDE which is -1.

You can use it as VibrationEffect.DEFAULT_AMPLITUDE
