加载多个 AdMob 视频

Question

出于演示目的，该应用程序有一个 activity 仅提供以下内容：

你点击一个按钮，观看一个奖励视频，你会得到任何奖励。

问题

如何加载视频？据我所见，您只能调用 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());

导致仅加载最后一个视频并在日志中显示：

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：很明显我对这个问题的思考是错误的。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给予不同的奖励（例如，一个给予金币，一个给予升级，等等）。没有理由加载5个视频。我应该在 onCreate() 中载入一个，以便在需要时准备就绪，然后在物品获得奖励后再次载入，以便下次使用。

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的奖励？

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...删除其余部分。不需要其他单元，你可以在监听器中跟踪任何你喜欢的东西。

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

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