Native Anzeige nicht in Flutter -App geladen trotz der korrekten Fabrik -ID -Registrierung ⇐ Android

[Anonymous]

Ich integriere Admob in meine Flutter -App mit dem Plugin von Google_Mobile_Ads. Belohnte Anzeigen funktionieren gut, aber meine native Anzeige lädt nicht. Ich habe überprüft, ob die AD -IDs korrekt sind und dass die Werks -ID "AdfactoryExample" zwischen meinem Fluttercode und dem nativen Android -Code übereinstimmt. Unten finden Sie die relevanten Codesegmente: < /p>

class _HomeScreenState extends State {
RewardedAd? _rewardedAd;
bool _isRewardedAdReady = false;

// Native ad fields.
NativeAd? _nativeAd;
bool _isNativeAdLoaded = false;

@override
void initState() {
super.initState();
_loadRewardedAd();
_loadNativeAd(); // Load the native ad on initialization.
}

void _loadRewardedAd() {
RewardedAd.load(
adUnitId: 'ca-app-pub-rewardId', // Replace with your rewarded ad unit ID.
request: const AdRequest(),
rewardedAdLoadCallback: RewardedAdLoadCallback(
onAdLoaded: (RewardedAd ad) {
_rewardedAd = ad;
setState(() {
_isRewardedAdReady = true;
});
},
onAdFailedToLoad: (LoadAdError error) {
print('RewardedAd failed to load: $error');
setState(() {
_isRewardedAdReady = false;
});
},
),
);
}

// New method to load the native ad.
void _loadNativeAd() {
_nativeAd = NativeAd(
adUnitId: 'ca-app-pub-nativeId', // Replace with your native ad unit ID.
factoryId: 'adFactoryExample', // Must match the native side.
request: const AdRequest(),
listener: NativeAdListener(
onAdLoaded: (ad) {
setState(() {
_isNativeAdLoaded = true;
});
print('Native ad loaded.');
},
onAdFailedToLoad: (ad, error) {
ad.dispose();
print('Native ad failed to load: $error');
setState(() {
_isNativeAdLoaded = false;

_nativeAd!.load();
}

if (_isRewardedAdReady && _rewardedAd != null) {
_rewardedAd!.show(

Ich habe doppelt überprüft, dass die Werks-ID "AdfactoryExample" zwischen meinem Flattern und meinem nativen Code konsistent ist. Belohnte Anzeigen laden und werden korrekt angezeigt, aber die native Anzeige erscheint nie. Hat jemand irgendwelche Vorschläge darüber, was möglicherweise dazu führt, dass die native Anzeige nicht laden oder angezeigt wird?>
