谷歌AdMob广告接入2——最白话，手把手教你做系列。_google admob app id 填写在哪里

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

插屏广告平时不怎么用。但模式是一样的。

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。
