Mit den WebView-APIs für Anzeigen werden App-Signale für die Tags in Ihrem CustomTabSession verfügbar gemacht. So können Webpublisher, die die Inhalte bereitgestellt haben, ihren Umsatz steigern und Werbetreibende werden vor Spam geschützt.
Funktionsweise
Die Kommunikation mit dem Google Mobile Ads SDK (Beta) erfolgt nur als Reaktion auf Anzeigenereignisse, die durch Folgendes ausgelöst werden:
Das Google Mobile Ads SDK (Beta) erleichtert die Kommunikation, indem ein postMessage-Channel mit dem CustomTabsSession des Android-Frameworks geöffnet wird.
Vorbereitung
- Google Mobile Ads SDK (Beta) 0.6.0-alpha01 oder höher
- Eine vorhandene Implementierung von benutzerdefinierten Chrome-Tabs in Ihrer mobilen App. Weitere Informationen finden Sie unter Aufwärmen und Vorabruf: Verwenden des Custom Tabs Service.
- Verknüpfen Sie Ihre mobile App mit einer Website über Digital Asset Links. Eine Anleitung finden Sie unter PostMessage für TWA.
App-ID an das SDK übergeben
Wenn Sie bereits eine Ad Manager-Anwendungs-ID haben, initialisieren Sie das Google Mobile Ads SDK (Beta) mit Ihrer vorhandenen Anwendungs-ID.
Wenn Sie keine Ad Manager-Anwendungs-ID haben, übergeben Sie InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID als Anwendungs-ID, wenn Sie das Google Mobile Ads SDK (Beta) initialisieren:
Kotlin
MobileAds.initialize(
this@MainActivity,
// Use this application ID to initialize the Google Mobile Ads SDK (beta) if
// you don't have an Ad Manager 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 Google Mobile Ads SDK (beta) if
// you don't have an Ad Manager application ID.
new InitializationConfig.Builder(InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID)
.build(),
initializationStatus -> {
// Adapter initialization is complete.
});
Implementierung
Ändern Sie in Ihrer Implementierung von benutzerdefinierten Chrome-Tabs den Code im onCustomTabsServiceConnected()-Callback. Ersetzen Sie newSession() durch MobileAds.registerCustomTabsSession(). Dadurch wird eine Verbindung zum postMessage-Channel hergestellt, um die Anzeigen-Tags mit SDK-Signalen anzureichern. Zum Verbinden des postMessage-Channels ist ein Digital Asset Link erforderlich. Optional können Sie den Parameter CustomTabsCallback festlegen, um auf Ereignisse von benutzerdefinierten Chrome-Tabs zu warten.
Sie sollten weiterhin Nachrichten über den CustomTabsSession senden können, der vom Google Mobile Ads SDK (Beta) empfangen wurde. Der Port kann sich jedoch ändern, wenn das SDK einen neuen Channel anfordert, der den vorhandenen überschreibt.
Das folgende Code-Snippet zeigt, wie Sie ein CustomTabsSession-Objekt mit dem Google Mobile Ads SDK (Beta) registrieren:
Kotlin
import com.google.android.libraries.ads.mobile.sdk.MobileAds
class MainActivity : ComponentActivity() {
private var customTabsClient: CustomTabsClient? = null

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,
packageName,
object : CustomTabsServiceConnection() {
override fun onCustomTabsServiceConnected(
name: ComponentName, client: CustomTabsClient,

customTabsClient = client
// Warm up the browser process.

// Create a new browser session using the Google Mobile Ads SDK (beta).
customTabsSession = MobileAds.INSTANCE.registerCustomTabsSession(
client,
// Checks the "Digital Asset Link" to connect the postMessage channel.

customTabsCallback

// unable to create one.

customTabsSession = client.newSession(customTabsCallback)
}
// Pass the custom tabs session into the intent.
val customTabsIntent = CustomTabsIntent.Builder(customTabsSession).build()
customTabsIntent.launchUrl(this@MainActivity,
Uri.parse("YOUR_URL"))
}
