android - 将 AdColony 与中介集成时无法第二次加载广告

Question

我已经通过 AdColony 的中介实现了 Admob 的奖励视频广告。广告加载正常，但当我更改设备方向或退出应用程序并返回时，广告无法加载，错误代码为 3，这是一个无填充错误。由于我使用的是测试广告，因此应该不会出现此错误。每次我重新安装该应用程序或在将其从最近的屏幕上滑出后打开它时，广告都会加载。

我在我的日志输出中得到以下内容:

上面堆栈跟踪中提到的行是这样的:

 @Override
public void onResume() {
    mRewardedVideoAd.resume(DrawerAndFragmentActivity.this);
    super.onResume();
}

我该怎么做才能解决这个问题？

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 build.gradle 中的“com.google.android.gms:play-services-ads:15.0.1”。
