Unity and AdMob [Google Ads] demo don't show ADS

Question

I have a trouble about Google Ads since a week. I download admob plugin from googleads/googleads-mobile-unity

Ver: 3.0.4

then opened I import package and implement demo script below:

using System;
using UnityEngine;
using GoogleMobileAds;
using GoogleMobileAds.Api;

public class GoogleMobileAdsDemoHandler : IDefaultInAppPurchaseProcessor
{
    private readonly string[] validSkus = { "android.test.purchased" };

    //Will only be sent on a success.
    public void ProcessCompletedInAppPurchase(IInAppPurchaseResult result)
    {
        result.FinishPurchase();
        GoogleMobileAdsDemoScript.OutputMessage = "Purchase Succeeded! Credit user here.";
    }

    //Check SKU against valid SKUs.
    public bool IsValidPurchase(string sku)
    {
        foreach(string validSku in validSkus)
        {
            if (sku == validSku)
            {
                return true;
            }
        }
        return false;
    }

    //Return the app's public key.
    public string AndroidPublicKey
    {
        //In a real app, return public key instead of null.
        get { return null; }
    }
}

// Example script showing how to invoke the Google Mobile Ads Unity plugin.
public class GoogleMobileAdsDemoScript : MonoBehaviour
{

    private BannerView bannerView;
    private InterstitialAd interstitial;
    private RewardBasedVideoAd rewardBasedVideo;
    private float deltaTime = 0.0f;
    private static string outputMessage = "";

    public static string OutputMessage
    {
        set { outputMessage = value; }
    }

    void Start()
    {
        // Get singleton reward based video ad reference.
        rewardBasedVideo = RewardBasedVideoAd.Instance;

        // RewardBasedVideoAd is a singleton, so handlers should only be registered once.
        rewardBasedVideo.OnAdLoaded += HandleRewardBasedVideoLoaded;

    {
        // Calculate simple moving average for time to render screen. 0.1 factor used as smoothing
        // value.

in editor log suggest that script work correctly displaying logs dummy load ad ,etc. But when I built and install to my device there is no ads?!

Do you have any idea what is wrong?

I have trying it on my device Xiaomi Mi4c only because i have no access to another Android device yet.

Answer 1

Try with test id's first. Real ad id's don't always match.

Reference: https://developers.google.com/admob/android/test-ads

Answer 2

Download those files from Admob Unity3d Plugin Project Home https://github.com/unity-plugins/Unity-Admob

Installation Admob Unity

Open your project in the Unity editor. Navigate to Assets -> Import Package -> Custom Package. Select the AdmobUnityPlugin.unitypackage file. Import all of the files for the plugins by selecting Import. Make sure to check for any conflicts with files. Unity Plugin Wiki and Documentation

1.Init Admob Unity Plugin Create A C# script ,drag the script to a object on scene , add the follow code in the script file

    using admob;
    Admob.Instance().initAdmob("admob banner id", "admob interstitial id");//admob id with format ca-app-pub-279xxxxxxxx/xxxxxxxx

2.Add Admob Banner in Unity App Here is the minimal code needed to show admob banner.

Admob.Instance().showBannerRelative(AdSize.Banner, AdPosition.BOTTOM_CENTER, 0);

The AdPosition class specifies where to place the banner. AdSize specifies witch size banner to show

3.Remove Banner By default, banners are visible. To temporarily hide a banner, call:

Admob.Instance().removeBanner();
