我已经通过AdColony的中介实施了Admob的奖励视频广告。广告可以很好地加载，但是当我更改设备方向或退出应用并返回时，广告无法加载，错误代码3，这是没有填充错误。由于我使用的是测试广告，因此不会发生此错误。每次我重新安装该应用程序或从“最近浏览”屏幕中将其刷除后打开它时，广告都会加载。
我在日志输出中得到以下信息：

上面的堆栈跟踪中提到的行是这样的：
@Override
public void onResume() {
mRewardedVideoAd.resume(DrawerAndFragmentActivity.this);
super.onResume();
}
我该怎么办才能解决这个问题？
最佳答案
请尝试更新到最新的AdColony SDK v3.3.5。 （https://github.com/AdColony/AdColony-Android-SDK-3）如果您使用的是AdMob中介，请使用最新的AdMob AdColony适配器v3.3.5.1。 （https://bintray.com/google/mobile-ads-adapters-android/com.google.ads.mediation.adcolony/3.3.5.1）另外，我建议使用
您build.gradle中的“ com.google.android.gms：play-services-ads：15.0.1”。
