为什么 Admob 广告没有出现在实际设备上？

Question

首先，前几天有些广告有效，但今天我注意到它们停止了工作，我不知道我是否改变了什么。

它们不能在任何设备上工作，而且我没有使用测试广告

在 Android Studio 的测试设备中，它们在顶部显示“测试广告”的小文字（我使用我的 admob id，所以这不是问题）但是当我制作 APK 并在设备广告根本不显示，甚至没有测试广告，它们就消失了，让我告诉你我的意思：

在测试虚拟设备中：https://gyazo.com/704e18c00544794ec4e29faad1a1ab8d

在实际设备中： https://imgur.com/a/iERofay

我会在这里放一些代码，但我不知道我应该放什么代码，所以我让你们告诉我要发送什么，以便你们看看有什么问题。

所有与广告有关的文件都在 gif 中： https://gyazo.com/8ca6c2b10e9b392c424f641ffaefb26a

（告诉我你要我发送什么文件，我会在这里发送）

（抱歉英语不好，我来自西班牙）

我用 ///////! 审查了广告 ID 和应用 ID！

Answer 1

创建您的 admob 帐户并添加您的应用后，您将获得您在清单中使用的应用程序 ID，并用于初始化广告。

现在您需要从您的 adMob 帐户为您的添加创建添加单元，并将您的添加单元 ID 与您在设备中显示的 addView 相关联。

如果您使用了网站的默认代码，则您可能正在使用 id 来测试广告单元。您需要将其替换为您的广告单元 ID。

发布应用后，您需要将 Google Play 上的应用与您的 adMob 帐户关联。

最后，添加只会在互联网连接可用时显示。

根据评论编辑

 <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
     android:value = "your-application-id-goes-here"/>

Make sure you have updated AdMob with your payment details
Make sure that the ads you created in AdMob are banner ads.
Check your AdMob dashboard to see the status of your ads, are they active?
Verify you used the correct Ad Unit Id.
Give it 24 hours, it can take time for an ad to become active in your region

请尝试遵循here 的指导方针。

检查代码中的以下行

    PublisherAdRequest adRequest = new PublisherAdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build();
    mPublisherAdView.loadAd(adRequest);

改为使用 ((AdView)findViewById(R.id.adView)).loadAd(new AdRequest.Builder().build());
