Admob插页广告的添加

在cocos2dx中加入Admob插页广告，不能用JNI直接调用

if (interstitial.isLoaded()) 
{
    interstitial.show();
                      
 }

显示插页广告的函数必须在mainUIThread中调用。

否则会报错：

IllegalStateException: XXXX must be called on the main UI thread.

所以要通过android handler传递消息来调用广告:

 private static Handler handler;
   private final static int HANDLER_GOTO_ADMOB = 1;
______________________________________________
 handler = new Handler() {

            public void handleMessage(Message msg) {
            switch (msg.what) {

            case HANDLER_GOTO_ADMOB:

        //    显示广告
                if (interstitial.isLoaded()) {
                      interstitial.show();
                      
                   }
                else
                {
                    AdRequest adRequest = new AdRequest.Builder().build();
                    interstitial.loadAd(adRequest);
                }
            break;

            case HANDLER_GOTO_OTHER:

        //    隐藏广告
                
            break;

            }

            }
        };

________________________________________________
  public static void displayInterstitial() {
        
    
        Message msg = new Message();
        msg.what = HANDLER_GOTO_ADMOB;
        handler.sendMessage(msg);
       
      }
