One of the reason you are getting error is you are initializing your ad with add unit ID instead of app ID.

// Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
MobileAds.initialize(this, "YOUR_ADMOB_APP_ID");


reference - https://developers.google.com/admob/android/quick-start#initialize_mobileads

Change code to reflect correct app_id which is located in ( Admob Console -> App->App Settings->App ID )

setContentView(R.layout.activity_main);
MobileAds.initialize(this, "ca-app-pub-3940256099942544/5224354917");
mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
mRewardedVideoAd.setRewardedVideoAdListener(this);
