在死线程Google Admob Rewarded视频上向处理程序发送消息

Question

在完成整个视频后,我从Google Admob的奖励视频屏幕回到我的活动时得到了这个堆栈跟踪.它只是警告,而不是崩溃. onRewardedVideoAdClosed()观看视频后调用方法,但onRewarded()不调用.任何帮助？

Answer 1

最近我正在研究 Google AdMob Reward 视频。显示奖励视频后，我的应用程序崩溃了。实际原因是，“onVideoClosed”回调是从后台线程调用的，并且从后台线程我错误地更新了 UI 元素，这必须通过主线程完成。

因此，请检查是否有任何 UI 元素通过后台线程以任何方式更新。
