加载多个 AdMob 视频

Question

出于演示目的，该应用有一个 Activity 仅提供以下功能：

你点击一个按钮，观看一个奖励视频，你就会得到任何奖励。

问题

如何加载视频？据我所知，您只能致电mAd.loadAd() 一次。有 3 个视频，每个视频都有自己的广告单元 ID。每个广告单元都可以有自己的监听器，但只加载一个视频，所以没关系...

尝试加载多个视频时

例如：

mAd1.loadAd("AD_UNIT_1", new AdRequest.Builder().build());
mAd2.loadAd("AD_UNIT_2", new AdRequest.Builder().build());
mAd3.loadAd("AD_UNIT_3", new AdRequest.Builder().build());

只加载最后一个视频，并记录在日志中：

W/Ads: Loading already in progress, saving this object for future refreshes.

onCreate()

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

    mAd1 = MobileAds.getRewardedVideoAdInstance(this);
    mAd2 = MobileAds.getRewardedVideoAdInstance(this);
    mAd3 = MobileAds.getRewardedVideoAdInstance(this);

    listeners...

    mAd1.loadAd() etc
}

感谢您的帮助

编辑：很明显我认为这个问题是错误的。我有 5 个以上的广告区，每个广告区都会播放一个奖励视频并提供不同的奖励（例如，一个提供硬币，一个提供升级，等等..）。没有理由加载 5 个视频。我应该在onCreate()中加载一个，以便在需要时准备好，然后在奖励项目后再次加载，以便下次准备。

所以问题仍然存在，如果只有一个视频，因此只有一个广告区正在加载onCreate()，那么我如何跟踪要给予什么奖励？

这是一个简单的解决方案...

MainActivity.java

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

    mAd = MobileAds.getRewardedVideoAdInstance(this);

    mAd.setRewardedVideoAdListener(new RewardedVideoAdListener() {

        @Override
        public void onRewarded(RewardItem rewardItem) {
            switch(Constants.currentAd) {
                case("REWARD1"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD2"):
                    //do something
                    Constants.currentAd = "";
                    break;

                case("REWARD3"):
                    //do something
                    Constants.currentAd = "";
                    break;
            }
        }
    });

   mAd.loadAd("REWARDED_VIDEO_UNIT_ID", new AdRequest.Builder().build());
}

public void showRewardedVideo() {
        if (mAd.isLoaded()) {
            mAd.show();
        }
    }

Constants.java

public class Constants {
    public static String currentAd = "";
}

点击按钮后显示广告

rewardButton1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Constants.currentAd = "REWARD1";
                dismiss();
                ((MainActivity) getActivity()).showRewardedVideo();
            }
        });

REWARDED_VIDEO_UNIT_ID 是 AdMob 中奖励视频的一个广告单元...删除其余的。无需其他单元，您可以在侦听器中跟踪您喜欢的任何内容。

        mAd.loadAd(adId, new AdRequest.Builder().build());
    }

    public void showVideo(){

        if (mAd.isLoaded()) {
            mAd.show();
        } else {

    MobileAds.initialize ( this, "ca-app-pub-4761500786576152~8215465788" );

    RewardedVideoAd mAd = MobileAds.getRewardedVideoAdInstance(this);
    mAd.setRewardedVideoAdListener(Video_Ad.this);

}

@Override
public void onRewardedVideoAdLoaded() {

}

@Override

}

@Override
