这几天忙着项目接入各种SDK，终于快忙完了。总结一波笔记。
GoogleAdMob是Google推出来的广告SDK，用于轻中度游戏的广告变现。
首先给出官方网站：https://admob.google.com/home/ （去这个网站给你的游戏创建GameID和广告ID）
然后给出开发者网站：https://developers.google.cn/admob/unity/start （这里会逐步讲解如何接入SDK）
当然，上面的两个网站都需要翻墙哈。
接下来我也做下笔记，如何接入GoogleAd的三种类型的广告（原生广告暂时不管）；不能翻墙的朋友也可以看我的笔记。
先总结一下基本流程：
获取Game ID --> 实例化SDK --> 请求相应的类型广告 --> 获取相应类型广告ID --> 创建广告实例
--> 发起请求广告 --> 显示广告（判断是否请求成功） ---> 每种类型广告都会有一些相应的回调方法
注意：使用下面显示的标记将您的AdMob 应用ID添加 到Unity应用目录中的AndroidManifest.xml文件中。您可以在AdMob用户界面中找到您的应用ID。用于在引号中插入您自己的AdMob App ID。自Google移动广告SDK版本17.0.0起，以下步骤是必需的。无法添加此<meta-data>标记会导致邮件崩溃： "The Google Mobile Ads SDK was initialized incorrectly."
<manifest>
<application>
<!-- Your AdMob App ID will look similar to this
sample ID: ca-app-pub-3940256099942544~3347511713 -->
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="[ADMOB_APP_ID]"/>
</application>
</manifest>
1.Banner 横幅广告
横幅广告是在屏幕上占据一处位置的矩形图片或文字广告。用户与应用互动时，这类广告会停留在屏幕上，并且可在一段时间后自动刷新。
using GoogleMobileAds.Api;
using System;
using UnityEngine;
public class AdController : MonoBehaviour {
private BannerView bannerView;
public string bannerAndID = "ca-app-pub-3940256099942544/6300978111";
public string bannerIosId = "ca-app-pub-3940256099942544/2934735716";
void Start () {
string appId = "unexpected_platform";
#if UNITY_ANDROID
appId = "ca-app-pub-3940256099942544~3347511713";
#elif UNITY_IPHONE
appId = "ca-app-pub-3940256099942544~1458002511";
#endif
//初始化 Google Mobile Ads SDK.
MobileAds.Initialize(appId);
RequestBanner();
}
/// <summary>
/// 请求Banner广告
/// </summary>
public void RequestBanner()
{
string adUnitId = "unexpected_platform";
#if UNITY_ANDROID
adUnitId = bannerAndID;
#elif UNITY_IPHONE
adUnitId = bannerIosID;
#endif
//实例化Banner
// adUnitId - BannerView加载广告单元的ID
// AdSize - Banner广告的相关尺寸（如果尺寸太大，可能Banner不会显示）
// AdPosition - banner广告显示的位置（枚举类型）
bannerView = new BannerView(adUnitId, AdSize.Banner, AdPosition.Top);
// 广告加载完成后调用
bannerView.OnAdLoaded += HandleOnAdLoadedBanner;
// 广告加载失败时调用
bannerView.OnAdFailedToLoad += HandleOnAdFailedToLoadBanner;
//当广告被点击时调用（记录 跟踪用户点击率的好地方）
bannerView.OnAdOpening += HandleOnAdOpenedBanner;
// 当玩家观看完广告后，点击返回游戏时调用（可以使用此方法恢复暂停的活动，或执行任何其他必要的操作，以做好互动准备。）
bannerView.OnAdClosed += HandleOnAdClosedBanner;
// 当玩家点击打开了其他应用程序（如Google Play）时调用（也就是点击广告跳转出去当前游戏了）
bannerView.OnAdLeavingApplication += HandleOnAdLeavingApplicationBanner;
// 创建一个请求
AdRequest request = new AdRequest.Builder().Build();
//通过请求去加载Banner.
bannerView.LoadAd(request);
}
//显示Banner
public void ShowBanner()
{
bannerView.Show();
}
//隐藏Banner
public void HideBanner()
{
bannerView.Hide();
}
#region Banner广告的回调函数
public void HandleOnAdLoadedBanner(object sender, EventArgs args)
{
print("HandleAdLoaded event received");
}
public void HandleOnAdFailedToLoadBanner(object sender, AdFailedToLoadEventArgs args)
{
print("HandleFailedToReceiveAd event received with message: "+ args.Message);
}
public void HandleOnAdOpenedBanner(object sender, EventArgs args)
{
print("HandleAdOpened event received");
}
public void HandleOnAdClosedBanner(object sender, EventArgs args)
{
print("HandleAdClosed event received");
}
public void HandleOnAdLeavingApplicationBanner(object sender, EventArgs args)
{
print("HandleAdLeavingApplication event received");
}
#endregion
}
注意：Banner加载后可自行显示Banner广告，ShowBanner()方法不是必须的，这个方法主要是对应HideBanner()方法的（便于隐藏后再次显示）。--2018.12.13 踩坑后再次更新笔记
Banner广告的尺寸和位置可以进行自定义
//自定义显示位置(原点是屏幕的左上角)
BannerView bannerView = new BannerView(adUnitId, AdSize.Banner, 0, 50);
//自定义尺寸
AdSize adSize = new AdSize(250, 250);
BannerView bannerView = new BannerView(adUnitId, adSize, AdPosition.Bottom);
//智能横幅广告（智能横幅广告会“智能”地检测设备当前屏幕方向的宽度，并据此设置与之等宽的广告视图，从而解决不同设备间屏幕尺寸不同的问题。）
BannerView bannerView = new BannerView(adUnitId, AdSize.SmartBanner, AdPosition.Top);
2.Interstitial 插页广告
插页式广告是覆盖其主机应用界面的全屏广告。它们通常显示在应用程序流程中的自然转换点，例如在游戏中各级别之间的暂停期间。当应用显示插页式广告时，用户可以选择点按广告并继续其目的地或关闭广告并返回应用。
using GoogleMobileAds.Api;
using System;
using UnityEngine;
public class AdController : MonoBehaviour {
private InterstitialAd interstitial;
public string InterstitialAndID = "ca-app-pub-3940256099942544/1033173712";
public string InterstitialIosAD = "ca-app-pub-3940256099942544/4411468910";
void Start () {
string appId = "unexpected_platform";
#if UNITY_ANDROID
appId = "ca-app-pub-3940256099942544~3347511713";
#elif UNITY_IPHONE
appId = "ca-app-pub-3940256099942544~1458002511";
#endif
//初始化 Google Mobile Ads SDK.
MobileAds.Initialize(appId);
}
/// <summary>
/// 请求Interstitial广告
/// </summary>
public void RequestInterstitial()
{
string adUnitId = "unexpected_platform";
#if UNITY_ANDROID
adUnitId = InterstitialAndID;
#elif UNITY_IPHONE
adUnitId = InterstitialIosAD;
#endif
//初始化InterstitialAd.
interstitial = new InterstitialAd(adUnitId);
//和banner类型的回调函数
interstitial.OnAdLoaded += HandleOnAdLoadedInterstitial;
interstitial.OnAdFailedToLoad += HandleOnAdFailedToLoadInterstitial;
interstitial.OnAdOpening += HandleOnAdOpenedInterstitial;
interstitial.OnAdClosed += HandleOnAdClosedInterstitial;
interstitial.OnAdLeavingApplication += HandleOnAdLeavingApplicationInterstitial;
// 创建一个请求.
AdRequest request = new AdRequest.Builder().Build();
// 通过请求去加载InterstitialAd.
interstitial.LoadAd(request);
}
/*注意：在iOS上，InterstitialAd对象是一次性使用对象。
* 这意味着，一旦显示插页式广告，该InterstitialAd对象就无法用于加载其他广告。
* 要请求其他插页式广告，您需要创建一个新 InterstitialAd对象。*/
/// <summary>
/// 显示Interstitial广告
/// </summary>
public void ShowInterstitial() {
if (interstitial.IsLoaded())
{
interstitial.Show();
}
}
#region Interstitial广告的回调函数
public void HandleOnAdLoadedInterstitial(object sender, EventArgs args)
{
print("HandleAdLoaded event received");
}
public void HandleOnAdFailedToLoadInterstitial(object sender, AdFailedToLoadEventArgs args)
{
print("HandleFailedToReceiveAd event received with message: "
+ args.Message);
}
public void HandleOnAdOpenedInterstitial(object sender, EventArgs args)
{
print("HandleAdOpened event received");
}
public void HandleOnAdClosedInterstitial(object sender, EventArgs args)
{
print("HandleAdClosed event received");
//当关闭一个Interstitial时，需要重新实例化一个
if (interstitial != null)
{
interstitial.Destroy();
}
RequestInterstitial();
}
public void HandleOnAdLeavingApplicationInterstitial(object sender, EventArgs args)
{
print("HandleAdLeavingApplication event received");
}
#endregion
}
注意：在iOS上，InterstitialAd对象是一次性使用对象。这意味着，一旦显示插页式广告，该InterstitialAd对象就无法用于加载其他广告。要请求其他插页式广告，需要创建一个新 InterstitialAd对象。
3.RewardVideo激励视频广告
奖励视频广告是全屏视频广告，用户可以选择全额观看， 以换取应用内奖励。
注意：RewardBasedVideoAd是单例
using GoogleMobileAds.Api;
using System;
using UnityEngine;
public class AdController : MonoBehaviour {
private RewardBasedVideoAd rewardBasedVideo;
public string RewardVideoAndID = "ca-app-pub-3940256099942544/5224354917";
public string RewardVideoIosID = "ca-app-pub-3940256099942544/1712485313";
void Start () {
string appId = "unexpected_platform";
#if UNITY_ANDROID
appId = "ca-app-pub-3940256099942544~3347511713";
#elif UNITY_IPHONE
appId = "ca-app-pub-3940256099942544~1458002511";
#endif
//初始化 Google Mobile Ads SDK.
MobileAds.Initialize(appId);
//RewardBasedVideoAd是单例
rewardBasedVideo = RewardBasedVideoAd.Instance;
//RewardVideo回调方法
rewardBasedVideo.OnAdLoaded += HandleRewardBasedVideoLoaded;
rewardBasedVideo.OnAdFailedToLoad += HandleRewardBasedVideoFailedToLoad;
rewardBasedVideo.OnAdOpening += HandleRewardBasedVideoOpened;
//广告开始播放时会调用此方法
rewardBasedVideo.OnAdStarted += HandleRewardBasedVideoStarted;
// 观看完视频获得奖励（Reward参数就是呈现给玩家的奖励）
rewardBasedVideo.OnAdRewarded += HandleRewardBasedVideoRewarded;
rewardBasedVideo.OnAdClosed += HandleRewardBasedVideoClosed;
rewardBasedVideo.OnAdLeavingApplication += HandleRewardBasedVideoLeftApplication;
}
/// <summary>
/// 请求RewardVideo
/// </summary>
public void RequestRewardVideo()
{
string adUnitId = "unexpected_platform";
#if UNITY_ANDROID
adUnitId = RewardVideoAndID;
#elif UNITY_IPHONE
adUnitId = RewardVideoIosID;
#endif
// 创建一个请求
AdRequest request = new AdRequest.Builder().Build();
// 根据请求去加载相关RewardVideo
rewardBasedVideo.LoadAd(request, adUnitId);
}
/// <summary>
/// 显示RewardVideo
/// </summary>
public void ShowRewardVideo() {
if (rewardBasedVideo.IsLoaded())
{
rewardBasedVideo.Show();
}
}
#region RewardVideo回调函数
public void HandleRewardBasedVideoLoaded(object sender, EventArgs args)
{
print("HandleRewardBasedVideoLoaded event received");
}
public void HandleRewardBasedVideoFailedToLoad(object sender, AdFailedToLoadEventArgs args)
{
print(
"HandleRewardBasedVideoFailedToLoad event received with message: "
+ args.Message);
}
public void HandleRewardBasedVideoOpened(object sender, EventArgs args)
{
print("HandleRewardBasedVideoOpened event received");
}
public void HandleRewardBasedVideoStarted(object sender, EventArgs args)
{
print("HandleRewardBasedVideoStarted event received");
}
public void HandleRewardBasedVideoClosed(object sender, EventArgs args)
{
print("HandleRewardBasedVideoClosed event received");
//重新加载RewardVideo
RequestRewardVideo();
}
public void HandleRewardBasedVideoRewarded(object sender, Reward args)
{
string type = args.Type;
double amount = args.Amount;
print(
"HandleRewardBasedVideoRewarded event received for "
+ amount.ToString() + " " + type);
}
public void HandleRewardBasedVideoLeftApplication(object sender, EventArgs args)
{
print("HandleRewardBasedVideoLeftApplication event received");
}
#endregion
}
总结：
1.每一种广告都有相应的回调函数；可以通过这些回调函数做一些“事情”：跟踪用户点击率；重新加载广告；给与玩家一定的奖励等等。
2.无论是哪种广告，你可以使用Google提供的测试ID去测试，但是你不能用自己的应用创建的广告ID去测试。除非在Google那里备案了，你将使用一台测试设备去测试你的应用广告ID。（不按规则走，可能会被封号）
3.官方Demo：https://github.com/googleads/googleads-mobile-unity/tree/master/samples/HelloWorld。
4.我的Demo: https://github.com/junyu-tu/Plugin-For-Unity/tree/master/GoogleAdmobDemo
5.使用Google测试ID走了一遍流程，如果发现RewardVideo不能播放，原因是：google 测试的广告ID 适用于海外，翻墙后就可以测试啦！！！
就是这样，我还会回来的！.png
