前言

此文章使用的版本为，Unity5.6.7f1、网络上有特殊需求，请自行解决

参考的主要网址来源于：https://developers.google.com/admob/unity/start

主要步骤为

后台申请广告 -> 环境部署&相关下载 -> Unity导入SDK并部署 -> 测试打包 -> 提取设备ID并填写 -> 无部署打包

最终目标即是最后一步，用以践行从Unity打包之后应该注意防止重复的操作，从而来节约宝贵的生命。

申请广告

去Admob申请开发者，创建应用 -> 创建需要展示的广告位。

此时需要使用到的有appid和广告位的id.

本地环境的部署

这里的环境指的是除基本的环境之外，还需要下载安装的东西

Unity的Android&Ios打包环境下载（此处最好都下载，因为随后sdk导入后，会有代码依赖，没有下载此在项目中报错）
Ios环境之下，安装 CocoaPods 。安装命令为 sudo gem install cocoapods，如有疑问，点击这里
下载Admob的Unity插件：跳转网址

Unity导入及相关操作

导入下载的Unity插件在你的项目中。如无意外，Android的配置Google服务会自动下载，手动的位置在这里Assets > Play Services Resolver > Android Resolver > Resolve

Android 配置

Assets/Plugins/Android/GoogleMobileAdsPlugin 目录下的 AndroidManifest.xml 文件中。您可以在 AdMob 界面中找到应用 ID。对于 android:value，请插入您自己的 AdMob 应用 ID，并加上英文引号，将 [ADMOB_APP_ID] 改为你的Android应用ID

<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>

<!-- 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>

IOS 配置

Assets/GoogleMobileAds/Editor 目录下的 PlistProcessor.cs 文件中，将ADMOB_APPLICATION_ID改为你的ios应用ID

    public static void OnPostProcessBuild(BuildTarget buildTarget, string path)
    {
        //#if UNITY_IPHONE
          // Replace with your iOS AdMob app ID. Your AdMob App ID will look
          // similar to this sample ID: ca-app-pub-3940256099942544~1458002511
          string appId = "ADMOB_APPLICATION_ID";

          string plistPath = Path.Combine(path, "Info.plist");
          PlistDocument plist = new PlistDocument();

          plist.ReadFromFile(plistPath);
          plist.root.SetString("GADApplicationIdentifier", appId);
          File.WriteAllText(plistPath, plist.WriteToString());
        //#endif
    }

public static void OnPostProcessBuild(BuildTarget buildTarget, string path)

{

//#if UNITY_IPHONE

// Replace with your iOS AdMob app ID. Your AdMob App ID will look

// similar to this sample ID: ca-app-pub-3940256099942544~1458002511

string appId = "ADMOB_APPLICATION_ID";

string plistPath = Path.Combine(path, "Info.plist");

PlistDocument plist = new PlistDocument();

plist.ReadFromFile(plistPath);

plist.root.SetString("GADApplicationIdentifier", appId);

File.WriteAllText(plistPath, plist.WriteToString());

//#endif

}

2020-05-25 补充：由于使用了CocoaPods进行项目的维护，开始觉得下载拉取慢，于是网上找教程搜到了清华镜像一类的解决方案，经过测试，我成功的浪费了两天时间，这其中包括了：

删除原来的git库（cocoapods) -》使用国内的重新git clone -》在我的项目中 pod install -> 报错，查找解决方案，最终无果 -> 删除cocoapods（包括相关的库，全删，删干净） -> 重新拉取github的原始的cocoapods（这之间有去设置git 下载速度慢以及相关设置，实测Git下载速度最终能达到100kb/s）-> 安装与设置cocoapods -> 在我的项目中 pod install -> 成功！

通用广告脚本

2020-05-25补充：

升级SDK v5.1.0，Unity IOS 编辑器上实例化报错，搜索相关问题之后，Google的回答是在真机上不没有问题；我对此的评价是：不负责的回答，预编译可以用，工作量小，能模拟虚拟环境，以至项目能够继续开发。

EntryPointNotFoundException: GADUInitializeWithCallback
GoogleMobileAds.iOS.MobileAdsClient.Initialize (System.Action`1[T] initCompleteAction) (at Assets/GoogleMobileAds/Platforms/iOS/MobileAdsClient.cs:53)
GoogleMobileAds.Api.MobileAds.Initialize (System.Action`1[T] initCompleteAction) (at Assets/GoogleMobileAds/Api/MobileAds.cs:64)

EntryPointNotFoundException: GADUInitializeWithCallback

GoogleMobileAds.iOS.MobileAdsClient.Initialize (System.Action`1[T] initCompleteAction) (at Assets/GoogleMobileAds/Platforms/iOS/MobileAdsClient.cs:53)

GoogleMobileAds.Api.MobileAds.Initialize (System.Action`1[T] initCompleteAction) (at Assets/GoogleMobileAds/Api/MobileAds.cs:64)

新版本SDK，支持了实时回调：即不用管Android是否在主线程上，在广告成功的回调中直接调用游戏的代码即可。

我在此提供一个广告通用的脚本，有需要的可以直接拿去使用：（新版本使用RewardedAd 类替换 RewardBasedVideoAd类)

这是一个通用模块，首先：你还需要做以下事情：

你需要在替换你的Android&Ios的广告相关的id。
在你的场景中新建游戏对象，并且挂上这个脚本，在检视板里勾上isTestModel。

中介的使用

Google Admob 广告中介，核心的解决广告填充不到位的问题，相当于广告联盟，区别于广告联盟的地方是你需要单独去第3方网站注册与在前端建立一广告、应用，提取广告帐户Key和广告的Key填入中介中。

https://developers.google.com/admob/unity/mediation 广告中介Doc位置，点击单个的广告会弹出相应的教程

Unity Ads 加入中介时遇到的问题

Unity后台找半天找不到Api Key，请参考这个网址：https://support.unity3d.com/hc/en-us/articles/115000564946-How-do-I-find-my-Unity-Ads-API-key-

Applovin 加入中介

尼玛，还得打个包前台才显示应用创建页面。

最后之前

Android打包可以直接Build。

Ios打包步骤这里需要强调一下：

Unity里面Build Setting里，请填好你的Team ID，以免每次都在XCode里面修改。
Unity > Build
导出工程所在地，请注意，直接打开xcworkspace,直接打开xcworkspace,直接打开xcworkspace，然后Build到真机即可
Android和IOS都是在Log里面，提取设备ID，重新填入到代码，然后重加包

Android & IOS的Log类似如下

<span class="pln"><Google> To get test ads on this device, call:
request.testDevices = @[ "2077ef9a63d2b398840261c8221a0c9b" ];</span>

1 2	<span class="pln"><Google> To get test ads on this device, call: request.testDevices = @[ "2077ef9a63d2b398840261c8221a0c9b" ];</span>

<span class="pln">I</span><span class="pun">/</span><span class="typ">Ads</span><span class="pun">:</span> <span class="typ">Use</span> <span class="typ">AdRequest</span><span class="pun">.</span><span class="typ">Builder</span><span class="pun">.</span><span class="pln">addTestDevice</span><span class="pun">(</span><span class="str">"33BE2250B43518CCDA7DE426D04EE232"</span><span class="pun">)</span><span class="pln">
to </span><span class="kwd">get</span><span class="pln"> test ads on </span><span class="kwd">this</span><span class="pln"> device</span><span class="pun">.</span>

I/Ads: Use AdRequest.Builder.addTestDevice("33BE2250B43518CCDA7DE426D04EE232")

to get test ads on this device.

将Log里面的ID添加到代码里面的 test_deviceId 里，然后重新打包，并测试你的广告。

最后

上面提供的脚本中，你仍然需要做的几件事：

你需要在TODO的界面加入你自身应用的逻辑。
在你的场景需要的地方，调用这个脚本提供的广告显示与隐藏的相关代码。
上线之前isTestModel属性设置为false.

祝君好运！
