搭配使用 Google Mobile Ads SDK 和 Open Measurement

Open Measurement 是 IAB 標準，可讓發布商使用第三方可視度評估服務供應商，驗證曝光和點擊評估資料。Google Mobile Ads SDK 從 18.1.0 版開始支援開放式評估。這個版本和後續版本的 Google Mobile Ads SDK
會與 Open Measurement (OM) SDK 整合，
以便進行第三方可視度評估。
Google Mobile Ads SDK 支援 OM SDK 1.4 版。
必要條件
* Google Mobile Ads SDK
18.1.0
以上版本。
導入 Open Measurement
Google Mobile Ads SDK 會自動導入公開評估功能，並將「Google」做為公開評估合作夥伴名稱，用於透過 Google Mobile Ads SDK 放送的所有廣告。
如要使用第三方可視度評估服務供應商，請在 AdMob 使用者介面中設定，並將委刊項設為使用該可視度評估服務供應商。詳情請參閱「設定行動應用程式可視度評估服務供應商」。
確認透明重疊畫面不會遮擋內容
如要避免廣告遭到封鎖，遮蔽廣告的檢視區塊必須符合下列其中一項設定：
visibility = View.GONE 或 visibility = View.INVISIBLE
遮蔽檢視區塊的背景是否透明並不重要，檢視區塊的 Alpha 和可見度值會決定檢視區塊是否會遮蔽廣告。
如果 Open Measurement SDK 偵測到廣告遭到遮蔽，可視度供應商可能會因此判定曝光無法觀看。如要修正這個問題，請將檢視區塊的 Alpha 值設為 0，或將顯示設定設為 View.GONE 或 View.INVISIBLE。
疑難排解
導入 Open Measurement 時，請注意下列事項：
請務必向中介服務合作夥伴確認，他們是否支援所放送廣告的開放式評估功能。
如果廣告遭到重疊的檢視畫面遮蓋，可能無法註冊可視度評估。詳情請參閱「確保透明重疊畫面不會遮擋內容」。
在測試裝置 (包括 Android 模擬器) 上，系統會偵測到「測試廣告」標籤不會遮蔽廣告檢視區塊。

To fix this,\nset your view's alpha to `0` or\n\nset the visibility to `View.GONE` or `View.INVISIBLE`.\n\n\nTroubleshooting\n---------------\n\nBe aware of the following when implementing Open Measurement:\n\n- No support for [AdMob campaigns](//support.google.com/admob/answer/6162747).\n\n\u003c!-- --\u003e\n\n- You must check with the mediation partner to learn if they support Open\n Measurement for ads they render.\n\n- Ads that are obscured by overlaying views might not register viewability\n measurements.
