android - Admob 奖励视频 - 广告未加载

Question

我必须在当前项目的 android studio 中实现 Admob Reward Video。我已经尝试过一切，比如.. Youtube 教程、Admob 官方教程和脚本，但没有任何东西对我有用。请帮忙。期待有一个示例 android studio 项目，其中奖励视频被实施和工作。

这是我使用的代码：

package easyload.android.el.com.easyloadpk;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.reward.RewardItem;
import com.google.android.gms.ads.reward.RewardedVideoAd;
import com.google.android.gms.ads.reward.RewardedVideoAdListener;

public class OurSurvey extends AppCompatActivity implements RewardedVideoAdListener
{
    private RewardedVideoAd rvd;
    Button                  btn;
    private AdView          mAdView;
    TextView                txt;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_our_survey);

        btn     = (Button) findViewById(R.id.btnad);
        mAdView = findViewById(R.id.adView);
        txt     = (TextView) findViewById(R.id.textView);

     //...............................................................................
     //   AdRequest adRequest = new AdRequest.Builder().build();
     //   mAdView.loadAd(adRequest);
     //...............................................................................

        MobileAds.initialize(this,"ca-app-pub-3940256099942544~3347511713");
        rvd = MobileAds.getRewardedVideoAdInstance(this);
        rvd.setRewardedVideoAdListener(this);
      //................................................................................
        loadad();
      //  AdView adView = new AdView(this);
       // adView.setAdSize(AdSize.BANNER);
      //  adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
       //...............................................................................

        btn.setOnClickListener(new View.OnClickListener()
        {
          @Override
          public void onClick(View v)
          {
            if(rvd.isLoaded()){
                rvd.show();
            }
            else{
                txt.setText("cnt");
            }
          }
        });
    }

    private void loadad()
    {
      rvd.loadAd("ca-app-pub-3940256099942544/5224354917",new AdRequest.Builder().build());
    }

    @Override
    public void onRewardedVideoAdLoaded()
    {
      txt.setText("holalalala");
    }

    @Override
    public void onRewardedVideoAdOpened() {

    }

    @Override
    public void onRewardedVideoStarted() {

    }

    @Override
    public void onRewardedVideoAdClosed() {

    }

    @Override
    public void onRewarded(RewardItem rewardItem) {

    }

    @Override
    public void onRewardedVideoAdLeftApplication() {

    }

    @Override
    public void onRewardedVideoAdFailedToLoad(int i) {

    }

    @Override
    public void onRewardedVideoCompleted() {

    }

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

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

谢谢你
