java - 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 please.

Android:

import android.os.Vibrator;

public class Brid {

private Context context;
private static Brid instance;


public Brid()
{
    this.instance = this;
}

public static Brid instance()
{
    if(instance == null) {
        instance = new Brid();
    }
    return instance;
}

public void setContext(Context context) {
    this.context = context;
}



public void Vibrate()
{
    Vibrator v = (Vibrator) this.context.getSystemService(Context.VIBRATOR_SERVICE);
    v.vibrate(100);
}

}

Unity3D:

    public static void Vibrate(AndroidJavaObject Brid, AndroidJavaObject context)
{
    if (Brid == null)
    {
        using (AndroidJavaClass activityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        {
            context = activityClass.GetStatic<AndroidJavaObject>("currentActivity");
        }

        using (AndroidJavaClass pluginClass = new AndroidJavaClass("com.xxx.ultimatemobile.Brid"))
        {
            if (pluginClass != null)
            {
                Brid = pluginClass.CallStatic<AndroidJavaObject>("instance");
                Brid.Call<AndroidJavaObject>("setContext", context);
                Brid.Call<AndroidJavaObject>("Vibrate");
            }
        }
    }
}

Button Event:

public void vibrate()
    {
#if UNITY_ANDROID

        Bridge.Vibrate(null, null);

#endif
    }

Thanks in advance...

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 <UnityInstallationDirecory>EditorDataPlaybackEnginesAndroidPlayerApk, Copy the AndroidManifest.xml file to your <ProjectName>AssetsPluginsAndroid

2.Now open the copied Manifest file from <ProjectName>AssetsPluginsAndroid and add <uses-permission android:name="android.permission.VIBRATE"/> 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):

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.unity3d.player"
    android:versionCode="1"
    android:versionName="1.0">

  <uses-permission android:name="android.permission.VIBRATE"/>

    <application
    android:theme="@style/UnityThemeSelector"
    android:icon="@drawable/app_icon"
        android:label="@string/app_name"
        android:debuggable="true">
        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
        </activity>
    </application>
</manifest>

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<AndroidJavaObject>("currentActivity");
        sysService = currentActivity.Call<AndroidJavaObject>("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<bool>("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();
}
