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);             }
