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
