Migrating to v6
onAdEvent Removed
onAdEvent had two problems:
- Only one listener could be registered to an ad instance. Attempting to register a second listener replaced previous listeners
- There were type conflicts around the event payload because typescript didn't know which event was sent to the listener
In order to resolve these problems, onAdEvent is replaced by addAdEventListener and addAdEventsListener.
addAdEventListener
With each call to addAdEventListener, you add a listener for one specific event type. The event type to listen for is the first argument and your event handler is the second argument. The type event payload type for the handler is automatically inferred from the event type you passed.
import {
AdEventType,
RewardedAd,
RewardedAdEventType
} from 'react-native-google-mobile-ads';
const rewardedAd = RewardedAd.createForAdRequest('...');
-rewardedAd.onAdEvent((type, error, reward) => {
- if (type === RewardedAdEventType.LOADED) {
- console.log('Ad has loaded');
- }
- if (type === RewardedAdEventType.EARNED_REWARD) {
- console.log('User earned reward of ', reward);
- }
- if (type === AdEventType.ERROR) {
- console.log('Ad failed to load with error: ', error);
- }
-}
+rewardedAd.addAdEventListener(RewardedAdEventType.LOADED, () => {
+ console.log('Ad has loaded');
+});
+rewardedAd.addAdEventListener(RewardedAdEventType.EARNED_REWARD, (reward) => {
+ console.log('User earned reward of ', reward);
+});
+rewardedAd.addAdEventListener(AdEventType.ERROR, (error) => {
+ console.log('Ad failed to load with error: ', error);
+});
To unsubscribe from an event, call the function returned from addAdEventListener.
const unsubscribe = interstitialAd.addAdEventListener(AdEventType.LOADED, () => {
console.log('Ad has loaded');
});
// Sometime later...
unsubscribe();
addAdEventsListener
With addAdEventsListener, you can listen for all of event types as legacy onAdEvent did. The handler now passes an object with event type and payload. You have to cast the payload to a corresponding type in order to use in typescript.
import {
AdEventType,
RewardedAd,
RewardedAdEventType,
RewardedAdReward
} from 'react-native-google-mobile-ads';
const rewardedAd = RewardedAd.createForAdRequest('...');
-rewardedAd.onAdEvent((type, error, reward) => {
+rewardedAd.addAdEventsListener(({ type, payload }) => {
if (type === RewardedAdEventType.LOADED) {
console.log('Ad has loaded');
}
if (type === RewardedAdEventType.EARNED_REWARD) {
+ const reward = payload as RewardedAdReward;
console.log(`User earned reward, name: ${reward.name}, amount: ${reward.amount}`);
}
if (type === AdEventType.ERROR) {
+ const error = payload as Error;
console.log('Ad failed to load with error: ', error.message);
}
}
To unsubscribe from events, call the function returned from addAdEventsListener.
const unsubscribe = interstitialAd.addAdEventsListener(({ type, payload }) => {
console.log('Ad event: ', type, payload);
});
// Sometime later...
unsubscribe();
removeAllListeners
You can remove all listeners registered with addAdEventListener and addAdEventsListener by calling removeAllListeners method.
interstitialAd.addAdEventListener(AdEventType.LOADED, () => {
console.log('Ad has loaded');
});
interstitialAd.addAdEventsListener(({ type, payload }) => {
console.log('Ad event: ', type, payload);
});
// Sometime later...
interstitialAd.removeAllListeners();
