使用admob免费时无法使用离子4 cordova

Question

我有一个Ionic 4应用程序与admob免费插件。这是我展示横幅的代码：

admob.service.ts

` BannerAd(admobid) {
    let bannerConfig: AdMobFreeBannerConfig = {
      isTesting: false, 
      autoShow: true,
      id: admobid
    };
    this.admobFree.banner.config(bannerConfig);

    this.admobFree.banner.prepare().then(() => {
      // success
    }).catch(e => alert(e));
  }  `

在一个页面上，我像这样调用这个方法：

 this.admob.BannerAd(this.id);

测试广告工作良好，但当我想使用制作广告时，横幅显示为屏幕下的黑条。我在我的google控制台中收到了2个警告。

common.js:290本机:尝试调用AdMobFree.config，但Cordova不可用。确保在设备/模拟器中包含cordova.js或运行 common.js:290本机:尝试调用AdMobFree.prepare，但Cordova不可用。确保在设备/模拟器中包含cordova.js或运行

我已经尝试过几种解决方案

解决方案1

Ionic 4 and Cordova is not available

解决方案2

迁移到一个新的项目

如何在我的Ionic 4应用程序中显示制作广告？

Answer 1

3天后，我运行了以下命令：

ionic cordova build android --prod --release

我将APK文件上传到进行测试版测试。当我在手机上安装这个应用程序进行测试的时候。广告出现了，一切正常。
