Admob 横幅未显示

Question

我的 admob 横幅没有显示，我已经阅读了此处的指南 https://firebase.google.com/docs/admob/android/quick-start

主要活动

private AdView mAdView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    MobileAds.initialize(getApplicationContext(), "ca-app-pub-3940256099942544/6300978111");
    mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);
}

Answer 1

您输入广告单元 ID，而不是应用程序 ID。

MobileAds.initialize(getApplicationContext(), here your app id will come );

这是您的广告 ID，两者不同，只需更改上面的代码并输入应用程序 ID 而不是您的广告单元 ID。

这是您的广告单元 ID

ca-app-pub-3940256099942544/6300978111

希望这会起作用。干杯!
