Vibrate with duration and pattern

Question

I am working on a simple plugin. Now I am trying to add a vibrate property. But this code is not working. Where am I going wrong? My code is as follows. Can you help me plea

Answer 1

I see you have a solution. For those who don't want to use Java. You can do this from C# only.

1.Go to \Editor\Data\PlaybackEngines\AndroidPlayer\Apk, Copy the AndroidManifest.xml file to your Assets\Plugins\Android

2.Now open the copied Manifest file from Assets\Plugins\Android and add to it. Save, Build and Run. If this is a permission problem, that should now be solved.

What your AndroidManifest.xml should look like(Unity 5.4):

You don't even need to write Java plugin for simple vibration. This can be done with Unity's AndroidJavaClass and AndroidJavaObject classes.

Complete Vibration Plugin without Java.

using UnityEngine;
using System.Collections;

public class Vibrate
{

    public AndroidJavaClass unityPlayer;
    public AndroidJavaObject currentActivity;
    public AndroidJavaObject sysService;


    public void Vibrate()
    {
        unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        currentActivity = unityPlayer.GetStatic("currentActivity");
        sysService = currentActivity.Call("getSystemService", "vibrator");
    }

    //Functions from https://developer.android.com/reference/android/os/Vibrator.html
    public void vibrate()
    {
        sysService.Call("vibrate");
    }


    public void vibrate(long milliseconds)
    {
        sysService.Call("vibrate", milliseconds);
    }

    public void vibrate(long[] pattern, int repeat)
    {
        sysService.Call("vibrate", pattern, repeat);
    }


    public void cancel()
    {
        sysService.Call("cancel");
    }

    public bool hasVibrator()
    {
        return sysService.Call("hasVibrator");
    }
}

Usage:

Vibrate vibrate = new Vibrate();

if (vibrate.hasVibrator())
{
    //Vibrate
    vibrate.vibrate();

    //Vibrate for 500 milliseconds
    vibrate.vibrate(500);

    // Start without a delay
    // Vibrate for 200 milliseconds
    // Sleep for 2000 milliseconds
    long[] pattern = { 0, 200, 2000 };
    vibrate.vibrate(pattern, 0);

    //Cancel Vibration
    vibrate.cancel();
}
