Some versions (don't ask which one) of com.google.android.gms.ads.reward.RewardedVideoAdListener requires onRewardedVideoCompleted function. RNAdMobRewardedVideoAdModule class implements that class.
If you don't want to manage gms versions you can just create an empty function. I can't find any javascript call to that method anyway.
RNAdMobRewardedVideoAdModule.java
#Override
public void onRewardedVideoCompleted(){
}
If your version of react-native-admob has onRewardedVideoCompleted function and you are getting 'method doesnt override' error, then remove the #override annotation from method.
Kindly refer this link for the answer https://github.com/sbugert/react-native-admob/issues/316
