Admob RewardedVideoAd sometimes does not show video. For the first time, advertising is always shown. For the second or third time, advertising is not shown. In this case, I get such a log:
03-24 13:08:26.754 4458-4458/net.dailytoys.afterthecrash W/Ads: Could not show rewarded video ad from adapter.

My init method:
private void initAdMob () {
MobileAds.initialize(this, AD_MOB_ID);
mRewardedVideoBonusAd = MobileAds.getRewardedVideoAdInstance(this);
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
mRewardedVideoBonusAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {
@Override
public void onRewardedVideoAdLoaded() {
System.out.println(adLogPrefix + " rewarded (bonus) loaded.");
}
@Override
public void onRewardedVideoAdClosed() {
System.out.println(adLogPrefix + " rewarded (bonus) closed.");
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
}
@Override
public void onRewarded(RewardItem rewardItem) {
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
}
@Override
public void onRewardedVideoAdFailedToLoad(int i) {
actionResolverAndroid.logAnalyticEvent(AnalyticsKeys.AD_ERR_LOADING_REW_VIDEO);
new Handler().postDelayed(
new Runnable() {
@Override
public void run() {
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
}
},
1000 * 15 // 15 seconds
);
System.out.println(adLogPrefix + " error loading rew (bonus).");
}
});
}
I did everything as it is written in the official documentation. What could be the problem?
This is a known issue with AdMob rewarded videos.
Consider removing the request from the Rewarded-Callback and leave it in Closed-Callback, so you don't have both, and they can't interfere with each other.
@Override
public void onRewardedVideoAdClosed() {
System.out.println(adLogPrefix + " rewarded (bonus) closed.");
// REMOVE THIS LINE BELOW
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
}
@Override
public void onRewarded(RewardItem rewardItem) {
mRewardedVideoBonusAd.loadAd(ID_REW_BONUS, new AdRequest.Builder().build());
}
