אופטימיזציה של כרטיסיות בהתאמה אישית

ממשקי ה-API של תצוגת האינטרנט למודעות מאפשרים לתגים ב-CustomTabSession לגשת לאותות מהאפליקציה, וכך לשפר את המונטיזציה של בעלי האתרים שסיפקו את התוכן ולהגן על המפרסמים מפני ספאם.

איך זה עובד

התקשורת עם GMA Next Gen SDK מתבצעת רק בתגובה לאירועים שקשורים למודעות, שמופעלים על ידי כל אחד מהגורמים הבאים:

‫GMA Next Gen SDK מאפשר תקשורת על ידי פתיחת ערוץ postMessage עם CustomTabsSession שסופק על ידי מסגרת Android.

דרישות מוקדמות

העברת מזהה האפליקציה אל ה-SDK

אם כבר יש לכם מזהה אפליקציה ב-AdMob, אתחלו את GMA Next Gen SDK עם מזהה האפליקציה הקיים.

אם אין לכם מזהה אפליקציה ב-AdMob, צריך להעביר את הערך InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID כמזהה האפליקציה כשמפעילים את GMA Next Gen SDK:

Kotlin

MobileAds.initialize(
    this@MainActivity,
    // Use this application ID to initialize the GMA Next Gen SDK if
    // you don't have an AdMob application ID.
    InitializationConfig.Builder(InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID)
        .build(),
  ) {
    // Adapter initialization complete.
  }

Java

MobileAds.initialize(
    this,
    // Use this application ID to initialize the GMA Next Gen SDK if
    // you don't have an AdMob application ID.
    new InitializationConfig.Builder(InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID)
        .build(),
        initializationStatus -> {
          // Adapter initialization is complete.
          });

הטמעה

במסגרת ההטמעה של כרטיסיות מותאמות ב-Chrome, משנים את הקוד ב-callback של onCustomTabsServiceConnected(). מחליפים את newSession() ב-MobileAds.registerCustomTabsSession(). הפעולה הזו יוצרת חיבור לערוץ postMessage כדי להוסיף אותות SDK לתגי המודעות. כדי לקשר את ערוץ postMessage צריך Digital Asset Link. אופציונלי, אפשר להגדיר את הפרמטר CustomTabsCallback כדי להאזין לאירועים של כרטיסיות מותאמות אישית ב-Chrome.

עדיין אמורה להיות לכם אפשרות לשלוח הודעות מ-CustomTabsSession שהתקבלו מ-GMA Next Gen SDK, אבל יכול להיות שהיציאה תשתנה כשה-SDK יבקש ערוץ חדש שיחליף את הערוץ הקיים.

קטע הקוד הבא מראה איך לרשום CustomTabsSession באמצעות GMA Next Gen SDK:

Kotlin

import com.google.android.libraries.ads.mobile.sdk.MobileAds

class MainActivity : ComponentActivity() {
  private var customTabsClient: CustomTabsClient? = null
  private var customTabsSession: CustomTabsSession? = null

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Get the default browser package name, this will be null if
    // the default browser does not provide a CustomTabsService.
    val packageName = CustomTabsClient.getPackageName(applicationContext, null);
    if (packageName == null) {
      // Do nothing as service connection is not supported.
      return
    }

    CustomTabsClient.bindCustomTabsService(
      applicationContext,

            customTabsClient?.warmup(0L)
            // Create a new browser session using the GMA Next Gen SDK.
            customTabsSession = MobileAds.INSTANCE.registerCustomTabsSession(
              client,

              ORIGIN,
