   多看源码：
   public interface JSCallback {
     /**
      * invoke javascript callback method, this method will destoryed after invoke.
      * @param data
      */
     void invoke(Object data);
   
     /**
      * invoke javascript callback method and keep callback alive for later use.
      * @param data
      */
     void invokeAndKeepAlive(Object data);
   }
