android - Admob 奖励视频测试广告未加载

Question

我已经在我的应用程序中实现了 Admob。我正在使用测试广告进行测试。 横幅和Interstitial TestAds运行良好，但奖励视频广告失败并出现代码 3

我不知道，这是怎么回事。两者都运行良好，但激励视频广告未加载。

在 Gradle 中使用 compile 'com.google.android.gms:play-services-ads:11.8.0'。

我的代码:

mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
mRewardedVideoAd.setRewardedVideoAdListener(this);
mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
                 new AdRequest.Builder().addTestDevice(getResources().getString(R.string.MyTestDevice)).build());

我完全使用了您的代码并且工作正常。你可以看看:

public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener{
    private RewardedVideoAd mRewardedVideoAd;
    Button btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn = findViewById(R.id.btn_ad);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (mRewardedVideoAd.isLoaded()) {
                    mRewardedVideoAd.show();
                }
            }
        });
        mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
        mRewardedVideoAd.setRewardedVideoAdListener(this);
        mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
            new AdRequest.Builder().build());
    }

    @Override
    public void onRewardedVideoAdLoaded() {

    }

    @Override
    public void onRewardedVideoAdOpened() {

    }

    @Override
    public void onRewardedVideoStarted() {

    }

    @Override
    public void onRewardedVideoAdClosed() {
        mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
            new AdRequest.Builder().build());
    }

    @Override
    public void onRewarded(RewardItem rewardItem) {
        mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
            new AdRequest.Builder().build());
    }

    @Override
    public void onRewardedVideoAdLeftApplication() {

    }

    @Override
    public void onRewardedVideoAdFailedToLoad(int i) {
        mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
            new AdRequest.Builder().build());
    }
}
