Banner Werbung mit Xamarin.Forms

Question

Ich möchte nur über die Banner-Werbung mit Xamarin.Forms ohne Patch oder Lücke zu unterstützen. Gibt es einen Anbieter, der seine SDKs mit den Xamarin.Forms bereitstellt?

Vielen Dank im Voraus.

Es gibt sowohl SDK als auch Schritt-für-Schritt-Beispiele für Google AdMob für Xamarin.Android. Sie werden die Xamarin.GooglePlaySerives.Ads nugget benötigen.

Ich verwende es, um Anzeigen in meiner Xamarin.Forms App zu zeigen, die bei Google Play veröffentlicht wurde.

Hier ist der Beispielcode für den Android-Teil Ihrer Anwendung:

using System; 

using Android.App; 
using Android.Content; 
using Android.Runtime; 
using Android.Views; 
using Android.Widget; 
using Android.OS; 
using Android.Support.V7.App; 
using Android.Gms.Ads; 
using Android; 

namespace AdMobExample 
{ 
    [Activity (Label = "@string/app_name", MainLauncher = true)] 
    public class MainActivity : AppCompatActivity 
    { 
     protected AdView mAdView; 
     protected InterstitialAd mInterstitialAd; 
     protected Button mLoadInterstitialButton; 

     protected override void OnCreate (Bundle savedInstanceState) 
     { 
      base.OnCreate (savedInstanceState); 
      SetContentView (Resource.Layout.activity_main); 

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

      mInterstitialAd = new InterstitialAd (this); 
      mInterstitialAd.AdUnitId = GetString (Resource.String.test_interstitial_ad_unit_id); 

      mInterstitialAd.AdListener = new AdListener (this); 

      mLoadInterstitialButton = FindViewById<Button> (Resource.Id.load_interstitial_button); 
      mLoadInterstitialButton.SetOnClickListener (new OnClickListener (this)); 
     } 

     protected void RequestNewInterstitial() 
     { 
      var adRequest = new AdRequest.Builder().Build(); 
      mInterstitialAd.LoadAd (adRequest); 
     } 

     protected void BeginSecondActivity() 
     { 
      var intent = new Intent (this, typeof(SecondActivity)); 
      StartActivity (intent); 
     } 

     protected override void OnPause() 
     { 
      if (mAdView != null) { 
       mAdView.Pause(); 
      } 
      base.OnPause(); 
     } 

     protected override void OnResume() 
     { 
      base.OnResume(); 
      if (mAdView != null) { 
       mAdView.Resume(); 
      } 
      if (!mInterstitialAd.IsLoaded) { 
       RequestNewInterstitial(); 
      } 
     } 

     protected override void OnDestroy() 
     { 
      if (mAdView != null) { 
       mAdView.Destroy(); 
      } 
      base.OnDestroy(); 
     } 

     class AdListener : Android.Gms.Ads.AdListener 
     { 
      MainActivity that; 

      public AdListener (MainActivity t) 
      { 
       that = t; 
      } 

      public override void OnAdClosed() 
      { 
       that.RequestNewInterstitial(); 
       that.BeginSecondActivity(); 
      } 
     } 

     class OnClickListener : Java.Lang.Object, View.IOnClickListener 
     { 
      MainActivity that; 

      public OnClickListener (MainActivity t) 
      { 
       that = t; 
      } 

      public void OnClick (View v) 
      { 
       if (that.mInterstitialAd.IsLoaded) { 
        that.mInterstitialAd.Show(); 
       } else { 
        that.BeginSecondActivity(); 
       } 
      } 
     } 
    } 
} 

Es gibt auch eine ste-für-Schritt-Anleitung für AdMob-Anzeigen für Xamarin.iOS:

using Google.MobileAds; 
... 

const string intersitialId = "<Get your ID at google.com/ads/admob>"; 

Interstitial adInterstitial; 

public override void ViewDidLoad() 
{ 
    base.ViewDidLoad(); 

    CreateAndRequestInterstitial(); 
} 

public void AfterSomeTime() 
{ 
    if (adInterstitial.IsReady) 
     adInterstitial.PresentFromRootViewController (navController); 
} 

void CreateAndRequestInterstitial() 
{ 
    adInterstitial = new Interstitial (intersitialId); 
    adInterstitial.ScreenDismissed += (sender, e) => { 
     // Interstitial is a one time use object. That means once an interstitial is shown, HasBeenUsed 
     // returns true and the interstitial can't be used to load another ad. 
     // To request another interstitial, you'll need to create a new Interstitial object. 
     adInterstitial.Dispose(); 
     adInterstitial = null; 
     CreateAndRequestInterstitial(); 
    }; 

    var request = Request.GetDefaultRequest(); 
    // Requests test ads on devices you specify. Your test device ID is printed to the console when 
    // an ad request is made. GADBannerView automatically returns test ads when running on a 
    // simulator. After you get your device ID, add it here 
    request.TestDevices = new [] { Request.SimulatorId.ToString() }; 

    adInterstitial.LoadRequest (request); 
}
