Android+阿里大鱼+java/beans/Introspector，进来看看吧兄弟

发现网上很多这个问题，但就是没什么正确的解决方案，决定和阿里的技术支持聊聊天

跟客服聊了一阵，印象最深就是下面这话，心理十万个草泥马奔腾而过。



但也只是瞬间经过而已，依赖javase的那肯定能在android上运行。只是他封装那个jar包不支持而已。

(大概浏览了一下jar包代码，真不懂写那么复杂是为啥~)

解决思路就是找回阿里巴巴旗下的APIjava版代码例子，然后去模拟请求

　　以上亲测可用。其中我只修改了SendMsg和CallAPI，其他那些函数都是官网上有现成的，别以为全是我自己写的。。。That‘s all 希望能帮到大家。
