AdMob

The code below was designed to be used by a Unity plugin that I have written. It's incomplete, only shoing the important bits. The C# files on Unity's end basically use AndroidJavaObject to interface with this java code. The code can't be copy-pasted as a whole to run, but it may shed some light on how to utilize the new AdMob.

 public void StartAd(final boolean testing, final String deviceID, final boolean positionAtTop)  
   {  
     Log.d("AdsPlugin", "StartAd was called");  
     activity = UnityPlayer.currentActivity;  
     activity.runOnUiThread(new Runnable()  
     {  
       @Override  
       public void run()  
       {  
         Log.d("AdsPlugin", "runOnUiThread started");  
         layout = new LinearLayout(activity.getApplicationContext());  
         layout.setGravity(((positionAtTop) ? Gravity.TOP : Gravity.BOTTOM) | Gravity.CENTER_HORIZONTAL);  
         activity.addContentView(layout, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));  
         adView = new AdView(activity);  
         adView.setAdUnitId(pubID);  
         adView.setAdSize(adSize);  
         adView.setAdListener(new AdListener()  
         {  
           @Override  
           public void onAdLoaded()  
           {  
             if (callbackHandlerName != null)  
             {  
               UnityPlayer.UnitySendMessage(callbackHandlerName, "onAdLoaded", "");  
             }  
           }  
           @Override  
           public void onAdFailedToLoad (int errorCode)  
           {  
             if (callbackHandlerName != null)  
             {  
               UnityPlayer.UnitySendMessage(callbackHandlerName, "onAdFailedToLoad", Integer.toString(errorCode));  
             }  
           }  
         });  
         if (testing)  
         {  
           adView.loadAd(new AdRequest.Builder().addTestDevice(deviceID).build());  
         }  
         else  
         {  
           adView.loadAd(new AdRequest.Builder().build());  
         }  
       }  
     });  
   }  
   public void ShowAd(String unused)  
   {  
     activity.runOnUiThread(new Runnable()  
     {  
       @Override  
       public void run()  
       {  
         layout.addView(adView, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));  
         layout.invalidate();  
         layout.requestLayout();  
       }  
     });  
   }  
   public void HideAd(String unused)  
   {  
     activity.runOnUiThread(new Runnable()  
     {  
       @Override  
       public void run()  
       {  
         layout.removeView(adView);  
         layout.invalidate();  
         layout.requestLayout();  
       }  
     });  
   }  
 }
