閱讀一些客戶成功案例: 個案研究 1, 個案研究 2。本指南說明如何將獎勵廣告整合至 Unity 應用程式。
必要條件
- 完成入門指南。
一律使用測試廣告進行測試
以下程式碼範例包含廣告單元 ID,供您請求 測試廣告該功能已設定為傳回測試廣告,而不是 導入及導入廣告,以備不時之需。
不過,在 AdMob 網頁介面中註冊應用程式,並建立要用於應用程式的廣告單元 ID 後,請在開發期間明確將裝置設為測試裝置。
Android
ca-app-pub-3940256099942544/5224354917
iOS
ca-app-pub-3940256099942544/1712485313
初始化 Mobile Ads SDK
在載入廣告之前,請讓應用程式呼叫 MobileAds.Initialize()
,初始化 Mobile Ads SDK。這項操作只需進行一次,最好在應用程式啟動時。
using GoogleMobileAds;
using GoogleMobileAds.Api;
public class GoogleMobileAdsDemoScript : MonoBehaviour
{
public void Start()
{
// Initialize the Google Mobile Ads SDK.
MobileAds.Initialize((InitializationStatus initStatus) =>
{
// This callback is called once the MobileAds SDK is initialized.
});
}
}
如果您使用中介服務,請等待回呼發生後再載入廣告,這樣可確保所有中介服務轉接程式都已初始化。
導入作業
整合獎勵廣告的主要步驟如下:
- 載入獎勵廣告
- [選用] 驗證伺服器端驗證 (SSV) 回呼
- 顯示獎勵廣告與獎勵回呼
- 監聽獎勵廣告事件
- 清理獎勵廣告
- 預先載入下一個獎勵廣告
載入獎勵廣告
系統會使用靜態 Load()
方法,完成載入獎勵廣告
RewardedAd
類別。系統會在完成處理常式中,將已載入的 RewardedAd
物件做為參數提供。以下範例說明如何載入
RewardedAd
。
// These ad units are configured to always serve test ads.
#if UNITY_ANDROID
private string _adUnitId = "ca-app-pub-3940256099942544/5224354917";
#elif UNITY_IPHONE
private string _adUnitId = "ca-app-pub-3940256099942544/1712485313";
#else
private string _adUnitId = "unused";
#endif
private RewardedAd _rewardedAd;
/// <summary>
/// Loads the rewarded ad.
/// </summary>
public void LoadRewardedAd()
{
// Clean up the old ad before loading a new one.
if (_rewardedAd != null)
{
_rewardedAd.Destroy();
_rewardedAd = null;
}
Debug.Log("Loading the rewarded ad.");
// create our request used to load the ad.
var adRequest = new AdRequest();
// send the request to load the ad.
RewardedAd.Load(_adUnitId, adRequest,
(RewardedAd ad, LoadAdError error) =>
{
// if error is not null, the load request failed.
if (error != null || ad == null)
{
Debug.LogError("Rewarded ad failed to load an ad " +
"with error : " + error);
return;
}
Debug.Log("Rewarded ad loaded with response : "
+ ad.GetResponseInfo());
_rewardedAd = ad;
});
}
[選用] 驗證伺服器端驗證 (SSV) 回呼
需要在伺服器端驗證作業中使用額外資料的應用程式
回呼應使用獎勵廣告的自訂資料功能。
在獎勵廣告物件上設定的任何字串值都會傳遞至 custom_data
SSV 回呼的查詢參數。如果未設定自訂資料值,
custom_data
查詢參數值不會顯示在 SSV 回呼中。
以下程式碼範例示範如何在 已載入獎勵廣告。
// send the request to load the ad.
RewardedAd.Load(_adUnitId, adRequest, (RewardedAd ad, LoadAdError error) =>
{
// If the operation failed, an error is returned.
if (error != null || ad == null)
{
Debug.LogError("Rewarded ad failed to load an ad with error : " + error);
return;
}
// If the operation completed successfully, no error is returned.
Debug.Log("Rewarded ad loaded with response : " + ad.GetResponseInfo());
// Create and pass the SSV options to the rewarded ad.
var options = new ServerSideVerificationOptions
.Builder()
.SetCustomData("SAMPLE_CUSTOM_DATA_STRING")
.Build()
ad.SetServerSideVerificationOptions(options);
});
如要設定自訂獎勵字串,就必須在顯示 廣告。
顯示獎勵廣告與獎勵回呼
顯示廣告時,您必須提供回呼來處理
使用者。廣告每次載入時只能顯示一次。使用 CanShowAd()
方法
確認廣告已經準備好可以放送。
以下程式碼是顯示獎勵廣告的最佳方法。
public void ShowRewardedAd()
{
const string rewardMsg =
"Rewarded ad rewarded the user. Type: {0}, amount: {1}.";
if (rewardedAd != null && rewardedAd.CanShowAd())
{
rewardedAd.Show((Reward reward) =>
{
// TODO: Reward the user.
Debug.Log(String.Format(rewardMsg, reward.Type, reward.Amount));
});
}
}
監聽獎勵廣告事件
如要進一步自訂廣告行為,您可以連結至 事件中的事件 (例如開啟和關閉等等)。如要監聽這些事件,請註冊委派函,如以下所示。
private void RegisterEventHandlers(RewardedAd ad)
{
// Raised when the ad is estimated to have earned money.
ad.OnAdPaid += (AdValue adValue) =>
{
Debug.Log(String.Format("Rewarded ad paid {0} {1}.",
adValue.Value,
adValue.CurrencyCode));
};
// Raised when an impression is recorded for an ad.
ad.OnAdImpressionRecorded += () =>
{
Debug.Log("Rewarded ad recorded an impression.");
};
// Raised when a click is recorded for an ad.
ad.OnAdClicked += () =>
{
Debug.Log("Rewarded ad was clicked.");
};
// Raised when an ad opened full screen content.
ad.OnAdFullScreenContentOpened += () =>
{
Debug.Log("Rewarded ad full screen content opened.");
};
// Raised when the ad closed full screen content.
ad.OnAdFullScreenContentClosed += () =>
{
Debug.Log("Rewarded ad full screen content closed.");
};
// Raised when the ad failed to open full screen content.
ad.OnAdFullScreenContentFailed += (AdError error) =>
{
Debug.LogError("Rewarded ad failed to open full screen content " +
"with error : " + error);
};
}
清理獎勵廣告
使用 RewardedAd
完成後,請務必先呼叫 Destroy()
方法,再放棄對該方法的參照:
_rewardedAd.Destroy();
這會通知外掛程式,說明該物件已不再使用,以及該物件的記憶體 可收回這些物件。無法呼叫此方法會導致記憶體流失。
預先載入下一個獎勵廣告
RewardedAd
是一次性的物件。也就是說,獎勵廣告顯示後
以再次使用物件如要請求其他獎勵廣告
您必須建立新的 RewardedAd
物件。
如要為下一個曝光商機準備獎勵廣告,請預先載入
OnAdFullScreenContentClosed
或
會引發 OnAdFullScreenContentFailed
個廣告事件。
private void RegisterReloadHandler(RewardedAd ad)
{
// Raised when the ad closed full screen content.
ad.OnAdFullScreenContentClosed += () =>
{
Debug.Log("Rewarded Ad full screen content closed.");
// Reload the ad so that we can show another as soon as possible.
LoadRewardedAd();
};
// Raised when the ad failed to open full screen content.
ad.OnAdFullScreenContentFailed += (AdError error) =>
{
Debug.LogError("Rewarded ad failed to open full screen content " +
"with error : " + error);
// Reload the ad so that we can show another as soon as possible.
LoadRewardedAd();
};
}
