How do I implement admob rewarded ads into unity

Question

using UnityEngine;
using System.Collections;
using GoogleMobileAds;
using GoogleMobileAds.Api;
using UnityEngine.Advertisements;

public class GameAdvertising : MonoBehaviour {

    public RewardBasedVideoAd rewardBasedVideo;
    bool hasPlayed;

    void Start () {
        rewardBasedVideo = RewardBasedVideoAd.Instance;
    }

    public void playAd()
    {
        AdRequest rewardrequest = new AdRequest.Builder().Build(); 
        rewardBasedVideo.LoadAd(rewardrequest, "ca-app-pub-5920324855307233/4458481507");
        rewardBasedVideo.Show();
    }
}

In my code above I have tried to implement the admob reward video ad into my game inside a method that is called from a ui button press. The advertise did not appear on my phone when the method was called (It works on the demo script and banners etc. works. I have imported all SDks and other files successful). What did I do wrong here and how do i put it in properly. Also how do i check when the ad is finished so i can reward the user?

You need to subscribe to OnAdRewarded Ad event with RewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;.

Just call RequestRewardBasedVideo() from the Start function to test this. This code below is from here and I modified it a little bit.

private void RequestRewardBasedVideo()
{
    #if UNITY_EDITOR
        string adUnitId = "unused";
    #elif UNITY_ANDROID
        string adUnitId = "INSERT_AD_UNIT_HERE";
    #elif UNITY_IPHONE
        string adUnitId = "INSERT_AD_UNIT_HERE";
    #else
        string adUnitId = "unexpected_platform";
    #endif

    RewardBasedVideoAd rewardBasedVideo = RewardBasedVideoAd.Instance;

    AdRequest request = new AdRequest.Builder().Build();
    rewardBasedVideo.LoadAd(request, adUnitId);

    //Show Ad
    showAdd(rewardBasedVideo);
}

private void showAdd(RewardBasedVideoAd rewardBasedVideo)
{
    if (rewardBasedVideo.IsLoaded())
    {
        //Subscribe to Ad event
        rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;
        rewardBasedVideo.Show();
    }
}

//This function is called when video ad has finished showing You can reward player here with the amount variable.

public void HandleRewardBasedVideoRewarded(object sender, Reward args)
{
    string type = args.Type;
    double amount = args.Amount;
    //Reawrd User here
    print("User rewarded with: " + amount.ToString() + " " + type);
}

Also make sure to put your ID **ca-app-pub-5920324855307233/4458481507** in `adUnitId`. — Programmer, May 17 '16 at 07:21
I was getting this error when I try to use same above code: https://drive.google.com/open?id=0B6CFlS0aZDPiZUFnbG9paTZUVEU — Siddharth, Dec 15 '16 at 12:25
@Siddharth Create a new question with your non working code for that and make sure to accept the answer you get if the answer solved your problem. Also provide a link to where you downloaded the admob plugin. — Programmer, Dec 15 '16 at 13:06

I using this plugin https://github.com/unity-plugins/Unity-Admob and code like this.

load video

   Admob.Instance().loadRewardedVideo("ca-app-pub-3940256099942544/1712485313");

Shown at game over , check that the video is ready before showing it:

   if (Admob.Instance().isRewardedVideoReady()) {
     Admob.Instance().showRewardedVideo();
   }

handle ad event

Admob.Instance().videoEventHandler += onInterstitialEvent;
    void onInterstitialEvent(string eventName, string msg)
    {
    Debug.Log("handler onAdmobEvent---" + eventName + "   " + msg);
    if (eventName == AdmobEvent.onAdLoaded)
    {
        Admob.Instance().showRewardedVideo();
    }
}
