Flutter google_mobile_ads 在 Android 模拟器中工作但不在发布应用程序中

Question

我对 google_mobile_ads 有疑问。 https://pub.dev/packages/google_mobile_ads

他们在 Android 模拟器、iOS 模拟器和 iOS 发布应用中工作，但不在发布应用中。

我将展示我的代码......即使我读到如果广告出现在模拟器中，它们也应该在发布应用程序中工作。

home.dart

 static List<String> adKeywords = [
    "keyword1",
    "keyword2",

  ];

  @override
  void initState() {
    super.initState();

    MobileAds.instance.initialize().then((InitializationStatus status) {
      print('Initialization done: ${status.adapterStatuses}');
      MobileAds.instance
          .updateRequestConfiguration(RequestConfiguration(
              tagForChildDirectedTreatment:
                  TagForChildDirectedTreatment.unspecified))
          .then((void value) {
        createInterstitialAd();
      });
    });
  }

  void createInterstitialAd() {
    _interstitialAd ??= InterstitialAd(
      adUnitId: InterstitialAd.testAdUnitId,
      // adUnitId: AdHelper.bannerAdUnitId, //this uses ad_helper.dart. code below
      request: AdRequest(
        // testDevices: <String>["kGADSimulatorID"],
        keywords: adKeywords,
        // contentUrl: 'http://example.com/bar.html',
        nonPersonalizedAds: true,
      ),
      listener: AdListener(
        onAdLoaded: (Ad ad) {
          print('${ad.runtimeType} loaded.');
          _interstitialReady = true;
        },
        onAdFailedToLoad: (Ad ad, LoadAdError error) {
          print('${ad.runtimeType} failed to load: $error.');
          ad.dispose();
          _interstitialAd = null;
          createInterstitialAd();
        },
        onAdOpened: (Ad ad) => print('${ad.runtimeType} onAdOpened.'),
        onAdClosed: (Ad ad) {
          Helpers().showToast("Refer 5 users to turn ads off.");
          print('${ad.runtimeType} closed.');
          ad.dispose();
          createInterstitialAd();
        },
        onApplicationExit: (Ad ad) =>
            print('${ad.runtimeType} onApplicationExit.'),
      ),
    )..load();
  }

ad_helper.dart

import 'dart:io';

class AdHelper {
  static String get bannerAdUnitId {
    if (Platform.isAndroid) {
      return "ca-app-pub-...";
    } else if (Platform.isIOS) {
      return "ca-app-pub-...";
    } else {
      throw new UnsupportedError("Unsupported platform");
    }
  }
}

AndroidManifest.xml - 从 Android 应用设置中添加 AppID

<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-..."/>

我也在终端中看到了这些错误：

绝对没问题。 当您达到 10-20 个活跃用户时，广告将自动开始展示。 ?
