I got this stacktrace while I came back to my activity from Google Admob's rewarded video screen after completing whole video. Its just warning, not crash. onRewardedVideoAdClosed() method is called after watching video, but onRewarded() does not called. Any help??

Recently I was working with Google AdMob Reward video. My app was crashing after reward video was displayed. The actual reason was, the "onVideoClosed" callback gets invoked from the background thread and from the background thread I was mistakenly updating an UI element, which must be done via Main thread.

So, please check if there are any UI elements being updated by any means from background thread.

i got the same error when i was using ad reward in 2 activities. I searched and found http://qaru.site/questions/1677496/admob-android-rewarded-video-not-showing-sometimes

the easy way out is not using 

 mRewardedVideoAd.destroy(this);
or 
 mRewardedVideoAd.destroy(getApplicationContext());

in onDestroy() even if in the official documentation it is written that you have to....
