谷歌AdMob广告接入2——最白话，手把手教你做系列。

仍然直奔主题，接入谷歌AdMob广告。申请广告ID不做赘述。这篇讲AdMob广告第二种接入方法。
首先，需求2个要素。
一，接入SDK
这次用的是谷歌原本的广告SDK下载地址

注意点击releases跳转的位置可以选择自己需要的SDK版本（PS:因为我其实一开始看到这种文档也是懵逼的，后来看的多了才知道在哪找自己需要的文件。）

下载完插件，把插件里包含的GoogleMobileAds.unitypackage的文件导入你的项目。
导入项目后你的project里面会出现以下文件。

第一步完成

二：代码部分

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

public class AdmobAds : MonoBehaviour {
    //单例模式，方便你在其他脚本直接引用
    public static AdmobAds instance;
    //激励视频广告
    public RewardBasedVideoAd rewardBasedVideo; 
    //插屏广告
    public InterstitialAd interstitial;
    private void Awake()
    {
        if (instance == null) instance = this;
        else if (instance != this) Destroy(gameObject);
    }


    public void Start()
    {

        // Get singleton reward based video ad reference.
        this.rewardBasedVideo = RewardBasedVideoAd.Instance;
        //以下为添加视频广告需要的事件
        // Called when an ad request has successfully loaded.
        rewardBasedVideo.OnAdLoaded += HandleRewardBasedVideoLoaded;
        // Called when an ad request failed to load.
        rewardBasedVideo.OnAdFailedToLoad += HandleRewardBasedVideoFailedToLoad;
        // Called when an ad is shown.

        // Called when the ad starts to play.
        rewardBasedVideo.OnAdStarted += HandleRewardBasedVideoStarted;
        // Called when the user should be rewarded for watching a video.
        rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;

        this.RequestRewardedVideo();
        RequestInterstitial();
    }


    private void RequestRewardedVideo()

        string adUnitId = "unexpected_platform";
#endif

        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the rewarded video ad with the request.
        this.rewardBasedVideo.LoadAd(request, adUnitId);
    }

    //以下为 我们Start中添加的事件对应的执行方法
    public void HandleRewardBasedVideoLoaded(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleRewardBasedVideoLoaded event received");
    }

    public void HandleRewardBasedVideoFailedToLoad(object sender, AdFailedToLoadEventArgs args)
    {
        MonoBehaviour.print(
            "HandleRewardBasedVideoFailedToLoad event received with message: "
                             + args.Message);
    }

    public void HandleRewardBasedVideoOpened(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleRewardBasedVideoOpened event received");
    }

    public void HandleRewardBasedVideoStarted(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleRewardBasedVideoStarted event received");
    }

    public void HandleRewardBasedVideoClosed(object sender, EventArgs args)
    {
        RequestRewardedVideo();
        MonoBehaviour.print("HandleRewardBasedVideoClosed event received");
    }

    public void HandleRewardBasedVideoRewarded(object sender, Reward args)
    {
       //视频广告奖励逻辑位置。此处可添加视频奖励的对应逻辑。
    }

    public void HandleRewardBasedVideoLeftApplication(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleRewardBasedVideoLeftApplication event received");
    }

    //请求插屏广告
    private void RequestInterstitial()
    {
#if UNITY_ANDROID
        string adUnitId = "ca-app-pub-7816725853485153/7041018637";

#endif

        // Initialize an InterstitialAd.
        interstitial = new InterstitialAd(adUnitId);
        // Called when an ad request has successfully loaded.
        interstitial.OnAdLoaded += HandleOnAdLoaded;
        // Called when an ad request failed to load.
        interstitial.OnAdFailedToLoad += HandleOnAdFailedToLoad;
        // Called when the ad is closed.
        interstitial.OnAdClosed += HandleOnAdClosed;
        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the interstitial with the request.
        interstitial.LoadAd(request);

    }
    //插屏广告对应事件
    public void HandleOnAdLoaded(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdLoaded event received");
    }

    public void HandleOnAdFailedToLoad(object sender, AdFailedToLoadEventArgs args)
    {
        MonoBehaviour.print("HandleFailedToReceiveAd event received with message: "
                            + args.Message);
    }

    public void HandleOnAdClosed(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdClosed event received");
    }


    //显示视频广告的方法，在需要显示的地方调用即可
    public void ShowReciveAds()
    {
        if (rewardBasedVideo.IsLoaded())
        {
            rewardBasedVideo.Show();
        }
        else
        {
            RequestRewardedVideo();
        }
    }
    //显示插屏广告的方法
    public void ShowInterstitial()
    {
        if (interstitial.IsLoaded())
        {
            interstitial.Show();
        }
        else
        {
            RequestInterstitial();
        }
    }

}

插屏广告平时不怎么用。但模式是一样的。

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

public class AdmobBannerAds : MonoBehaviour {
    private BannerView bannerView;

    public void Start()
    {
        this.RequestBanner();
    }

    private void RequestBanner()
    {
        //填写对应平台ID
#if UNITY_ANDROID
            string adUnitId = "ca-app-pub-3940256099942544/6300978111";
#elif UNITY_IPHONE
            string adUnitId = "ca-app-pub-3940256099942544/2934735716";
#else
        string adUnitId = "unexpected_platform";
#endif

        bannerView = new BannerView(adUnitId, AdSize.Banner, AdPosition.Top);

        // Called when an ad request has successfully loaded.
        bannerView.OnAdLoaded += HandleOnAdLoaded;
        // Called when an ad request failed to load.
        bannerView.OnAdFailedToLoad += HandleOnAdFailedToLoad;
        // Called when an ad is clicked.
        bannerView.OnAdOpening += HandleOnAdOpened;
        // Called when the user returned from the app after an ad click.
        bannerView.OnAdClosed += HandleOnAdClosed;
        // Called when the ad click caused the user to leave the application.
        bannerView.OnAdLeavingApplication += HandleOnAdLeavingApplication;

        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();

        // Load the banner with the request.
        bannerView.LoadAd(request);
    }

    public void HandleOnAdLoaded(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdLoaded event received");
    }

    public void HandleOnAdFailedToLoad(object sender, AdFailedToLoadEventArgs args)
    {
        MonoBehaviour.print("HandleFailedToReceiveAd event received with message: "
                            + args.Message);
    }

    public void HandleOnAdOpened(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdOpened event received");
    }

    public void HandleOnAdClosed(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdClosed event received");
    }

    public void HandleOnAdLeftApplication(object sender, EventArgs args)
    {
        MonoBehaviour.print("HandleAdLeftApplication event received");
    }

}
//显示Banner广告的方法，在需要显示的地方调用即可
  public void ShowBanner()
    {
        if (bannerView.IsLoaded())
        {
            bannerView.Show();
        }
        else
        {
            RequestBanner();
        }
    }

以上代码新手可直接覆用，只需要将对应的广告ID修改成自己的即可。
