Question

上周我遇到了一个错误，请更好地帮助我。我通过RewardedVideo实现了Admob，但是却得到了error 3和一段时间error 0。当我同时尝试test ads和{{1}时，这两个错误都面临着我}。

我的代码在下面。

real ads

我对 build.gradle 的依赖是

private RewardedVideoAd mRewardedVideoAd;
Button adsShow;
private static final String TAG = "MainActivity";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    MobileAds.initialize(this, "ca-app-pub-3940256099942544/5224354917");
    mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
    mRewardedVideoAd.setRewardedVideoAdListener(this);

    loadRewardedVideoAd();
    adsShow=(Button)findViewById(R.id.mainidads);
    adsShow.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mRewardedVideoAd.isLoaded()){
                mRewardedVideoAd.show();
            }
        }
    });

}
private void loadRewardedVideoAd() {

    if(!mRewardedVideoAd.isLoaded()) {

        mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
                new AdRequest.Builder().build());

    }
}

@Override
public void onRewardedVideoAdLoaded() {
    Toast.makeText(this, "onRewardedVideoAdLoaded", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdOpened() {
    Toast.makeText(this, "onRewardedVideoAdOpened", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoStarted() {
    Toast.makeText(this, "onRewardedVideoStarted", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdClosed() {
    loadRewardedVideoAd();
    Toast.makeText(this, "onRewardedVideoAdClosed", Toast.LENGTH_SHORT).show();
}

@Override
public void onRewarded(RewardItem rewardItem) {
    Toast.makeText(this, "onRewarded! currency: " + rewardItem.getType() + "  amount: " +
            rewardItem.getAmount(), Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdLeftApplication() {
    Toast.makeText(this, "onRewardedVideoAdLeftApplication",
            Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoAdFailedToLoad(int i) {
    Toast.makeText(this, "onRewardedVideoAdFailedToLoad "+i, Toast.LENGTH_SHORT).show();
}

@Override
public void onRewardedVideoCompleted() {

}

请帮助我。

Answer 1

出现错误的原因之一是您使用添加单元ID而不是应用ID来初始化广告。

// Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
        MobileAds.initialize(this, "YOUR_ADMOB_APP_ID");

参考-https://developers.google.com/admob/android/quick-start#initialize_mobileads

更改代码以反映位于（Admob控制台-> App-> App设置-> App ID）中的正确app_id

    setContentView(R.layout.activity_main);
    MobileAds.initialize(this, "ca-app-pub-3940256099942544/5224354917");
    mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
    mRewardedVideoAd.setRewardedVideoAdListener(this);

如果这不能解决您的问题，请使用错误日志更新您的问题

未显示测试广告，并且未添加用于Android的Admob奖励视频
