Cocos2d-x 调用 Android 代码的后续

我发现简单的调用没有任何问题。 但是只要是调用了UI元素，比如显示个消息框什么的，程序立即就挂了。后来发现还是得上Google（鄙视一下百度同学），在StackOverFlow上面找到了一篇这样的回答

The problem was that when calling back from JNI the application wasn't on UI Thread so the dialog was never shown. To fix it I used a Handler (on Activity):

public final Handler dialogHandler = new Handler(){     
    public void handleMessage(Message msg){
        showDialog(SOME_ID);
    }   
};

So instead of directly call showDialog() I do it by calling dialogHandler.sendMessage().

翻译过来，就是说，当前程序的主线程没有在UI上。所以对话框当然显示不出来。这个时候需要一个Handler和UI线程进行异步通信。具体的机制我也没太明白。但是好歹解决了问题。代码如下

以上是我作的电信计费测试代码。如果通过Handler调用，而不是直接调用，就不会出现死机问题。
