Reklamlar için web görünümü API'leri, uygulama sinyallerini CustomTabSession'inizdeki etiketlere sunar. Böylece, içeriği sağlayan web yayıncıları için para kazanmayı iyileştirir ve reklamverenleri spam'den korur.
İşleyiş şekli
Google Mobile Ads SDK'sı ile iletişim yalnızca aşağıdakilerden herhangi biri tarafından tetiklenen reklam etkinliklerine yanıt olarak gerçekleşir:
Google Mobile Ads SDK'sı, Android çerçevesi tarafından sağlanan CustomTabsSession ile bir postMessage kanalı açarak iletişimi kolaylaştırır.
Ön koşullar
- Google Mobile Ads SDK'sı 23.0.0 veya üstü.
- Mobil uygulamanızda mevcut bir Chrome özel sekmeleri uygulaması. Isınma ve ön getirme: Özel Sekmeler Hizmeti'ni kullanma başlıklı makaleyi inceleyin.
- Mobil uygulamanızı Digital Asset Links ile bir web sitesiyle ilişkilendirin.

Uygulama
Chrome özel sekmeleri uygulamanızda, onCustomTabsServiceConnected() geri çağırma işlevindeki kodu değiştirin. newSession() yerine MobileAds.registerCustomTabsSession() yazın. Bu işlem, reklam etiketlerini SDK sinyalleriyle zenginleştirmek için postMessage kanalı ile bağlantı oluşturur. postMessage kanalını bağlamak için bir Digital Asset Link gerekir. İsteğe bağlı olarak, CustomTabsCallback parametresini Chrome Özel Sekme etkinliklerini dinleyecek şekilde ayarlayabilirsiniz.
Google Mobile Ads SDK'sından alınan CustomTabsSession üzerinden mesaj göndermeye devam edebilirsiniz ancak SDK mevcut kanalı geçersiz kılan yeni bir kanal istediğinde bağlantı noktası değişebilir.
Aşağıdaki kod snippet'inde, Google Mobile Ads SDK'sı kullanılarak CustomTabsSession kaydının nasıl yapılacağı gösterilmektedir:
