如何将Admob与Webview集成

Question

我是一个php / web / mysql / css / js开发人员，对java和android都很新。我的第一个webview就像一个魅力，但我想知道为什么我的admob根本不工作。到目前为止，我从这里和www尝试了几个教程，但没有成功。我相信你们中的任何一个极客都会立即找到这个问题，所以提前谢谢。将在下面的主题中添加相关代码，请让我知道我这边有什么问题。如果您需要更多来源，我也可以在这里添加。

多数民众赞成我到目前为止：

的build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'

        classpath 'com.google.firebase:firebase-ads:15.0.1'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
