Error displaying ads - Android C # Xamarin

I am trying to display AdMob ads in my application, but I am getting an error. I added Google Play Services and all my code is tested, I also use my own AdMob ID for testing, and all the code from the AdMod tutorial. Is there anything I might have missed?

Main Activity Announcement Code:

 protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            //AdMob
            mAdView = (AdView)FindViewById<AdView>(Resource.Id.adView);
            AdRequest adRequest = new AdRequest.Builder().Build();
            mAdView.LoadAd(adRequest);
            //AdMob

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
            ActionBar.Hide();

      

Adsense ad code for Main.axml:

 <com.google.android.gms.ads.AdView
          xmlns:ads="http://schemas.android.com/apk/res-auto"
          android:id="@+id/adView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerHorizontal="true"
          android:layout_alignParentBottom="true"
          ads:adSize="BANNER"
          ads:adUnitId="HERE_MY_UNIT_ID">
  </com.google.android.gms.ads.AdView>

      

Error message:

Change the order. Your object mAdView

is Null because you didn't specify a contentView for the Activity.



protected override void OnCreate(Bundle bundle)
{
        base.OnCreate(bundle);
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);
        ActionBar.Hide();

        //AdMob
        mAdView = (AdView)FindViewById<AdView>(Resource.Id.adView);
        AdRequest adRequest = new AdRequest.Builder().Build();
        mAdView.LoadAd(adRequest);
        //AdMob
}
