这个是在加载本地方法的时候，应该是没有加载这个lib包，

未发现原因是，有很多so的包，其他的功能都是MFW的jar包里面封装好了，就是剩下两个没有封装进去，所以需要自己手动加载，加载后就有了

java.lang.UnsatisfiedLinkError:

No implementation found for void com.polycom.mfw.contentsend.ContentSendJNI.setContentType(int)

这个是找到方法，但是没有实现

现在来说，已经成功加载so，但是调用方法的时候并没有按照相应的位置去放置调用类，JNI有很严格的标准，方法名和返回值
