אופטימיזציה של כרטיסיות בהתאמה אישית (בטא)

ממשקי ה-API של תצוגות אינטרנט עבור מודעות הופכים את אותות האפליקציה לזמינים לתגים CustomTabSession עזרה בשיפור המונטיזציה לבעלי אתרים שסיפקו את התוכן וכדי להגן על המפרסמים מפני ספאם.

איך זה עובד

התקשורת עם Google Mobile Ads SDK מתבצעת רק בתגובה למודעה אירועים שהופעלו על ידי אחד או יותר מהגורמים הבאים:

Google Mobile Ads SDK מאפשר תקשורת על ידי פתיחת postMessage ערוץ עם CustomTabsSession שסופקה על ידי מסגרת Android.

דרישות מוקדמות

הטמעה

בהטמעה של הכרטיסיות המותאמות אישית ב-Chrome, משנים את הקוד onCustomTabsServiceConnected() קריאה חוזרת. מחליפים את newSession() עם MobileAds.registerCustomTabsSession(). כך נוצר חיבור עם ערוץ postMessage כדי להעשיר את תגי המודעות עם אותות SDK. נדרש קישור לנכס דיגיטלי כדי לחבר את ה-postMessage . אפשר גם להגדיר את CustomTabsCallback להאזנה לאירועים בכרטיסייה המותאמת אישית ב-Chrome.

עדיין יש לך אפשרות לשלוח הודעות מאפליקציית CustomTabsSession שהתקבלו מ-Google Mobile Ads SDK, אבל היציאה עשויה להשתנות כשה-SDK מבקש ערוץ חדש שיחליף את הערוץ הקיים.

קטע הקוד הבא מראה איך לרשום CustomTabsSession באמצעות SDK של מודעות Google לנייד:
