広告用のウェブビュー API を使用すると、
CustomTabSession
コンテンツを提供しているウェブ パブリッシャーの収益性向上に役立つ
広告主をスパムから守ります
仕組み
Google Mobile Ads SDK との通信は、広告の応答としてのみ行われます。 イベントがトリガーされます。
Google Mobile Ads SDK は、postMessage を開いてコミュニケーションを促進します
チャネルを、Android フレームワークによって提供される CustomTabsSession に置き換えます。
前提条件
- 既存の Chrome カスタムタブ 実装する方法を紹介します詳細については、ウォームアップとプリフェッチ: カスタムタブ サービス。
- デジタル アセット リンクを使用して、モバイルアプリをウェブサイトに関連付ける。
- Google Mobile Ads SDK 23.0.0 以降
実装
Chrome カスタムタブの実装で、
onCustomTabsServiceConnected()
呼び出すことができます。newSession() を交換します。
MobileAds.registerCustomTabsSession() の場合。
これにより、postMessage チャネルとの接続を確立して広告タグを拡充します
統合できますpostMessage を接続するには、デジタル アセット リンクが必要です
。必要に応じて、CustomTabsCallback を設定できます。
パラメータを使用して、Chrome のカスタムタブ イベントをリッスンします。
受信した CustomTabsSession からのメッセージは、引き続き送信できるはずです。
ポートは Google Mobile Ads SDK からリクエストされたときに
新しいチャンネルを作成する。
次のコード スニペットは、次のコマンドを使用して CustomTabsSession を登録する方法を示しています。
