Question

我想在我的Android应用程序上实现奖励视频，我第一次点击显示视频，工作得很好，但在那之后第二次或第三次点击再次显示它，它不起作用，并抛出日志：

    super.onPause();
}

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

你能帮忙弄清楚出了什么问题吗？感谢

Answer 1

<强>解

我遇到同样的问题并期待official example我发现他们没有打电话

RewardedVideoAd.destroy(Context)

虽然他们告诉他们在official tutorial中打电话。所以在删除后，它就可以了。

Answer 2

关于manual，您似乎需要重新加载视频：覆盖此方法

onRewardedVideoAdClosed() {
loadRewardedVideoAd();
}

Answer 3

如果您要求从admob获取广告，当您已经获得另一个关于从admob获取广告的视频请求时，您提出的第一个请求将返回广告并且您决定显示（）广告，您是获取无法显示来自适配器的奖励视频广告。错误。

我认为这是关于单身的某种方式。您提出的第二个请求会在第一个请求中中断。这会让人感到困惑，因为您可以创建com.google.android.gms.ads.reward.RewardedVideoAdListener()的多个实例。在我的情况下，如果您已经等待第一个请求，我们必须阻止第二个请求才能使用。

Answer 4

我遇到了完全相同的问题，经过几天的调查后我找到了解决方案。

您必须非常小心RewardedVideoAd生命周期。就我而言，我将活动生命周期与此对象联系起来。但是我明白，向onResume()对象调用RewardedVideoAd将会重新启动＆＃34;重新启动＆＃34;它，所以即使您之前加载了广告，也需要重新加载一个广告。

正如您可能在其他主题中找到的那样，即使SDK允许，也不要尝试同时加载广告。如果没有预先加载广告，或者刚刚调用onResume() RewardedVideoAd对象，请确保在您的广告系列中加载广告。

不要犹豫，记录您的RewardedVideoAd回调方法，以帮助您了解和优化广告加载流程。

Answer 5

我正在放置一个admob视频，当你进入活动时执行该视频，我在第二次进入活动时遇到了同样的问题。在我的情况下，我放了一个可执行循环来启动视频已经加载。

if (mRewardedVideoAd.isLoaded()) {
        mRewardedVideoAd.show();
    }else{
        loadRewardedVideoAd();
    }

这是我所有代码的一部分

private boolean started = false;
private Handler handler = new Handler();

private void initializeAdMob() {
    mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
    mRewardedVideoAd.setRewardedVideoAdListener(this);
    loadRewardedVideoAd();
}

private void loadRewardedVideoAd() {
    if (!mRewardedVideoAd.isLoaded()) {
        mRewardedVideoAd.loadAd(getString(R.string.id_block_activity), new AdRequest.Builder().build());
    }
}

private void showRewardedVideoAd() {
    if (BaseInteractor.isNetworkAvailable(this)) {
        showProgressBar(true);
        start();
    }
}

private Runnable runnable = new Runnable() {
    @Override
    public void run() {
        if (mRewardedVideoAd.isLoaded()) {
            mRewardedVideoAd.show();
        }else{
            loadRewardedVideoAd();
        }
        if (started) {
            start();
        }
    }
};

public void stop() {
    started = false;
    handler.removeCallbacks(runnable);
}

public void start() {
    started = true;
    handler.postDelayed(runnable, 2000);
}

最后我在

中停止了runnable

@Override
public void onRewardedVideoAdOpened() {
    showProgressBar(false);
    stop();
}

我希望这会对你有所帮助。

根据Google文档(link)获取新的奖励视频广告。

RewardedAd是一次性使用的对象。这意味着，一旦显示了奖励广告，该对象就无法用于加载其他广告。要请求另一个奖励广告，您需要创建一个新的RewardedAd对象。

因此，如果您需要第二个广告，则需要处理现有的rewardedAd对象并创建一个新对象。您可以这样做：

rewardedAd=null;
rewardedAd = new RewardedAd(this,"ca-app-pub-3940256099942544/5224354917");
