java - 如何使用 admob 在 android 中集成奖励视频广告？

Question

我想使用 admob 在我的 android 项目中添加奖励视频广告，我通过奖励视频将我的 android 应用程序货币化。我点击了这个链接 integrate rewarded video ad

这是mainActivity代码:

public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener {
private RewardedVideoAd mAd;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mAd = MobileAds.getRewardedVideoAdInstance(this);
    mAd.setRewardedVideoAdListener(this);

}

private void loadRewardedVideoAd() {
 mAd.loadAd(String.valueOf(R.string.ad_key), new AdRequest.Builder().addTestDevice("device id").build());
    Toast.makeText(this, "called", Toast.LENGTH_SHORT).show();

}
public void load(View view){
    loadRewardedVideoAd();
}


@Override
public void onRewardedVideoAdLoaded() {
    if (mAd.isLoaded()) {
        Toast.makeText(this, "is Loaded", Toast.LENGTH_SHORT).show();
        mAd.show();
    }else{
        Toast.makeText(this, "failed", Toast.LENGTH_SHORT).show();

    }
    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() {
    Toast.makeText(this, "onRewardedVideoAdClosed", Toast.LENGTH_SHORT).show();
}

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

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

@Override
public void onRewardedVideoAdFailedToLoad(int i) {

}
@Override
public void onResume() {
    mAd.resume(this);
    super.onResume();
}

@Override
public void onPause() {
    mAd.pause(this);
    super.onPause();
}

@Override
public void onDestroy() {
    mAd.destroy(this);
    super.onDestroy();
}
}

这是我的权限:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

当我运行我的代码时它显示

02-28 18:30:19.573 21418-21429/mainscreen.udeveloper.com.rewardedvideo W/Ads: There was a problem getting an ad response. ErrorCode: 1

02-28 18:30:19.583 21418-21418/mainscreen.udeveloper.com.rewardedvideo W/Ads: Failed to load ad: 1

我在谷歌上搜索了很多奖励视频广告教程，但我没有找到任何教程，请帮助我。 如果我应该使用另一个奖励视频广告网络，请指导我好的教程。
