实施Google Reward Video时遇到一个奇怪的问题。在测试模式（带有google ad-id）下，第一次完美运行，但第二次不加载视频。在生产中（带有我的ID）完全不加载视频。这是我的代码：

我仔细检查了我的ID，并且正确无误。也可能是我的代码，因为它完全可以正常工作。我会提供任何帮助或想法。

@Override
public void onRewardedVideoAdClosed() {
// Load the next rewarded video ad.
loadRewardedVideoAd();
}
第一个关闭后，我们需要重新加载。
由于相同，我的应用程序正常运行。希望有帮助。
