我正在尝试在片段中实施 admob 广告，但已经一个月了，我仍然收到错误 3（没有广告可填充）。
我已尝试使用新 ID，但仍然出现相同的错误，测试广告工作正常。日志猫：

我正在片段中实现广告，所以在上下文中我传递了 getActivity() ：
MobileAds.initialize(getActivity(), "xxxxxxxxxxxxxxxxxxx");
mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(getActivity());
mRewardedVideoAd.setRewardedVideoAdListener(rewardAdListener);
loadRewardedAdVideo();
奖励视频广告监听器
RewardedVideoAdListener rewardAdListener = new RewardedVideoAdListener() {
@Override
public void onRewardedVideoAdLoaded() {
Toast.makeText(getActivity(),"ad is loaded",Toast.LENGTH_SHORT).show();
Log.d("ADS_SHOW","loaded");
}
@Override
public void onRewardedVideoAdOpened() {
}
@Override
public void onRewardedVideoStarted() {
}
@Override
public void onRewardedVideoAdClosed() {
loadRewardedAdVideo();
}
@Override
public void onRewarded(RewardItem rewardItem) {
int rewardPoints = rewardItem.getAmount();
int userPoints = getActivity().getSharedPreferences(PREFERENCE,0).getInt(POINTS,0) - rewardPoints;
userRef.child(POINTS).setValue(userPoints);
getActivity().getSharedPreferences(PREFERENCE,0).edit().putInt(POINTS,userPoints).commit();
}
@Override
public void onRewardedVideoAdLeftApplication() {
}
@Override
public void onRewardedVideoAdFailedToLoad(int i) {
Toast.makeText(getActivity(),"No ads to show "+i,Toast.LENGTH_SHORT).show();
}
@Override
public void onRewardedVideoCompleted() {
}
};
private void loadRewardedAdVideo(){
if(! mRewardedVideoAd.isLoaded()){
mRewardedVideoAd.loadAd("ca-app-pub-xxxxxxxxx", new AdRequest.Builder().build());
}
}
