测试插页式广告正在我的模拟器上运行。但它们在我的真实设备上不起作用。

获取广告响应时出现问题。 ErrorCode: 0

W/Ads: Failed to load ad: 0

我打电话mInterstitialAd.show();的onNavigationItemSelected

这是我的主要活动代码

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener, OddsConversionFragment.OnFragmentInteractionListener,
    KellyCalculatorFragment.OnFragmentInteractionListener, PoissonCalculatorFragment.OnFragmentInteractionListener,
    TrixieFragment.OnFragmentInteractionListener{

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setupDrawerToolbar();
    createAndAddFragment();
    // Obtain the shared Tracker instance.
    AnalyticsApplication application = (AnalyticsApplication) getApplication();
    mTracker = application.getDefaultTracker();

    //Ads
    mInterstitialAd = new InterstitialAd(this);
    mInterstitialAd.setAdUnitId("ca-app-pub-82304873078*******"); //My Ad ID

    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
            requestNewInterstitial();
        }

    requestNewInterstitial();

任何帮助将不胜感激。

解决方案

今天我发现了问题所在。

我没有在我的onCreate方法上设置我的 App ID 代码。这里是：MobileAds.initialize(getApplicationContext(), "your AppID");

您可以在 AdMob 帐户中找到您的 AppID。

现在测试和真实广告都在工作！谷歌的肠道指南错过了它。他们只在横幅教程中写过……我就是这样发现的。
