插頁式獎勵廣告是一種獎勵廣告格式 獎勵 自動在應用程式的自然轉換期間自動切換。有別於獎勵廣告 必須啟用才能觀看插頁式獎勵廣告。本指南說明如何 整合 AdMob 的插頁式獎勵廣告 移至 Flutter 應用程式
必要條件
- Flutter 外掛程式 1.1.0 以上版本。
- 完成開始使用。您的 Flutter 應用程式應該已安裝 Google Mobile Ads Flutter 外掛程式 已匯入。
一律使用測試廣告進行測試
建構及測試應用程式時,請務必使用測試廣告,而非 現場及正式環境廣告否則可能導致帳戶遭到停權。
要載入測試廣告,最簡單的方法是使用我們專屬的測試廣告單元編號。 插頁式獎勵廣告:
Android
ca-app-pub-3940256099942544/5354046379
iOS
ca-app-pub-3940256099942544/6978759866
測試廣告單元會設為針對每個請求傳回測試廣告。 您可以在自己的應用程式中使用這些 API,編寫程式碼、測試及偵錯。 發布前,請確實將這些內容換成自己的廣告單元編號
載入廣告
以下範例會載入插頁式獎勵廣告:
class RewardedInterstitialExampleState extends State<RewardedInterstitialExample> { RewardedInterstitialAd? _rewardeInterstitialdAd; // TODO: replace this test ad unit with your own ad unit. final adUnitId = Platform.isAndroid ? 'ca-app-pub-3940256099942544/5354046379' : 'ca-app-pub-3940256099942544/6978759866'; /// Loads a rewarded ad. void loadAd() { RewardedInterstitialAd.load( adUnitId: adUnitId, adRequest: const AdRequest(), adLoadCallback: RewardedInterstitialAdLoadCallback( // Called when an ad is successfully received. onAdLoaded: (ad) { debugPrint('$ad loaded.'); // Keep a reference to the ad so you can show it later. _rewardedInterstitialAd = ad; }, // Called when an ad request failed. onAdFailedToLoad: (LoadAdError error) { debugPrint('RewardedInterstitialAd failed to load: $error'); }, )); } }
插頁式獎勵廣告事件
使用 FullScreenContentCallback
即可監聽生命週期
事件,例如廣告顯示或關閉時間。組合
RewardedInterstitialAd.fullScreenContentCallback
後,才向以下對象顯示廣告:
接收這些事件的通知。這個範例將實作每個方法
並記錄訊息至控制台
class RewardedInterstitialExampleState extends State<RewardedInterstitialExample> { RewardedInterstitialAd? _rewardedInterstitialAd; // TODO: replace this test ad unit with your own ad unit. final adUnitId = Platform.isAndroid ? 'ca-app-pub-3940256099942544/5354046379' : 'ca-app-pub-3940256099942544/6978759866'; /// Loads a rewarded ad. void loadAd() { RewardedInterstitialAd.load( adUnitId: adUnitId, adRequest: const AdRequest(), adLoadCallback: RewardedInterstitialAdLoadCallback( // Called when an ad is successfully received. onAdLoaded: (ad) { ad.fullScreenContentCallback = FullScreenContentCallback( // Called when the ad showed the full screen content. onAdShowedFullScreenContent: (ad) {}, // Called when an impression occurs on the ad. onAdImpression: (ad) {}, // Called when the ad failed to show full screen content. onAdFailedToShowFullScreenContent: (ad, err) { // Dispose the ad here to free resources. ad.dispose(); }, // Called when the ad dismissed full screen content. onAdDismissedFullScreenContent: (ad) { // Dispose the ad here to free resources. ad.dispose(); }, // Called when a click is recorded for an ad. onAdClicked: (ad) {}); debugPrint('$ad loaded.'); // Keep a reference to the ad so you can show it later. _rewardedInterstitialAd = ad; }, // Called when an ad request failed. onAdFailedToLoad: (LoadAdError error) { debugprint('RewardedInterstitialAd failed to load: $error'); }, )); } }
多媒體廣告
RewardedInterstitialAd
會在所有應用程式內容上方以重疊形式顯示
而且靜態位置因此無法新增至 Flutter 小工具樹狀結構。
您可以呼叫 show()
來選擇廣告的放送時機。
RewardedInterstitialAd.show()
會採用 OnUserEarnedRewardCallback
,並在使用者獲得獎勵時叫用。請務必導入這個功能,並獎勵
觀看廣告的使用者
_rewardedInterstitialAd.show(onUserEarnedReward: (AdWithoutView ad, RewardItem rewardItem) { // Reward the user for watching an ad. });
呼叫 show()
後,就無法移除以這種方式顯示的 Ad
需要使用者輸入內容RewardedInterstitialAd
只能
只會顯示一次後續要顯示的通話會觸發
onAdFailedToShowFullScreenContent
。
不再需要放送的廣告時,必須予以處理。最佳做法
何時該呼叫 dispose()
位於
「FullScreenContentCallback.onAdDismissedFullScreenContent
」和
FullScreenContentCallback.onAdFailedToShowFullScreenContent
回呼。
大功告成!您的應用程式現在可以顯示插頁式獎勵廣告了。
