Listener for onAdAboutToExpire on Android

Overview

A set of two callback methods are introduced under NativeAdEventListener API to notify the publisher when an ad is about to expire and when an ad is actually expired. When an ad is expired then the impression doesn't get counted for that ad. Additionally, if ad impression is logged before expiry then both the callback methods are invalidated.

Once onAdLoaded method is called, the user needs to set the NativeAdEventListener to get following callback methods:

• public void onAdAboutToExpire();

  This callback method is used to notify the publisher when an ad is about to expire.

• public void onAdExpired();

  This callback method is used to notify that an ad is expired.

The time interval for about to expire of an ad can be set using the variable Settings.NATIVE_AD_ABOUT_TO_EXPIRE_INTERVAL. The default value of about to expire time interval is 60*1000 milliseconds. This interval denotes the time period in milliseconds on the basis of which onAdAboutToExpire() callback is triggered. This method gets triggered at the number of milliseconds prior to actual expiry interval of the ad. Apart from the callbacks, an additional API has been exposed to register the NativeAdEventListener known as registerNativeAdEventListener.

For example:

Settings.NATIVE_AD_ABOUT_TO_EXPIRE_INTERVAL = <time in ms>; // Example: 2 * 60 * 1000

Methods

The following methods are supported in this feature:

Register with NativeAdEventListener

Registering the NativeAdEventListener is achieved using overloaded methods of NativeAdSDK.registerTracking().

final NativeAdEventListener nativeAdEventListener = new NativeAdEventListener() {
    @Override
    public void onAdWasClicked() {
    }
 
    @Override
    public void onAdWillLeaveApplication() {
    }
 
    @Override
    public void onAdWasClicked(String clickUrl, String fallbackURL) {
    }
 
    @Override
    public void onAdImpression() {
    }
 
    @Override
    public void onAdAboutToExpire() {
    }
 
    @Override
    public void onAdExpired() {
    }
}; 
NativeAdSDK.registerTracking(response, nativeContainer, nativeAdEventListener);

registerNativeAdEventListener

/**
 * Register the NativeAdResponse to listen to Native Ad events
 *
 * @param response  that contains the meta data of native ad
 * @param listener  called when Ad event happens, can be null
 */
public static void registerNativeAdEventListener(final NativeAdResponse response, final NativeAdEventListener listener);
NativeAdSDK.registerNativeAdEventListener(response, nativeAdEventListener);
