建議您使用數種最佳做法，確保使用 Android 版 IMA SDK 時，您的應用程式能在 Android TV 上正常運作。
請先熟悉開發 Android 版的 TV 應用程式。具體來說，請按照入門指南所述，確認您已為電視設定活動。此外，還建議您處理 TV 導覽功能，確保使用者能在 Android TV 上順暢瀏覽您的應用程式。
處理可略過的廣告
SDK 會針對類似電視的裝置最佳化可略過格式，例如移除與「瞭解詳情」按鈕互動的功能。根據預設，當可略過廣告可以使用時，SDK 會將焦點移至略過按鈕，以便在 Android TV 上略過廣告。因此，您無須額外進行設定即可支援可略過的廣告。
您可以透過呼叫 AdsRenderingSettings.setFocusSkipButtonWhenAvailable() 進行設定。
如要進一步瞭解支援的廣告，請參閱相容性矩陣。
處理 VAST 圖示備用廣告圖片
IMA SDK 會偵測、呈現及處理使用者與 VAST 圖示備用圖片的互動。應用程式應監聽 ICON_TAPPED 和 ICON_FALLBACK_IMAGE_CLOSED 事件，針對使用「為什麼會顯示這則廣告」(WTA) 的廣告處理廣告播放作業。
新增布林值即可追蹤 VAST 圖示備用廣告圖片是否顯示。然後，監聽 ICON_TAPPED 和 ICON_FALLBACK_IMAGE_CLOSED，以處理 VAST 圖示備用廣告圖片周圍的廣告播放。請參閱下列程式碼片段範例，瞭解進階範例中如何處理這項功能。
