title: Trying to use google play services ad feature in unity3D i don't have any errors but i can't see my ads
body: <p>I'm trying to add google-play-services's "com.google.androind.gms.ads" to my unity project to load ads i feel like i have come quite far as i no longer have any errors from calling the java classes. However i am now kind of stuck as i have no errors and no ads. </p>
  
  <p>Here´s the code in my unity c# class.</p>
  
  <pre><code>    Debug.Log("Instantiate STARTED");
      unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
      currActivityUnity = unityPlayer.GetStatic&lt;AndroidJavaObject&gt;("currentActivity");
      admobPluginClassAdSize = new AndroidJavaClass("com.google.android.gms.ads.AdSize");
      AndroidJavaObject adSize = admobPluginClassAdSize.GetStatic&lt;AndroidJavaObject&gt;("FULL_BANNER");
      admobPluginClassAdView = new AndroidJavaObject("com.google.android.gms.ads.AdView",
      currActivityUnity);
      admobPluginClassAdListener = new AndroidJavaClass("com.google.android.gms.ads.AdListener");
      admobPluginClassAdRequestBuilder = new AndroidJavaObject("com.google.android.gms.ads.AdRequest$Builder");
      admobPluginClassAdView.Call("setAdSize", adSize);
      admobPluginClassAdView.Call("setAdUnitId", pubID);
      admobPluginClassAdRequestBuilder = admobPluginClassAdRequestBuilder.Call&lt;AndroidJavaObject&gt;("addTestDevice", testDeviceId);
      admobPluginClassAdRequest = admobPluginClassAdRequestBuilder.Call&lt;AndroidJavaObject&gt;("build");
      currActivityUnity.Call("runOnUiThread", new AndroidJavaRunnable(() =&gt;
          {
              admobPluginClassAdView.Call("loadAd", admobPluginClassAdRequest);
          }));
      Debug.Log("Instantiate FINISHED");
