this warning is that reflective operations on this class will incorrectly
indicate that it is not an inner class.

遇到这个问题也是困扰了我好久，也在网上看了好多问题总结了几个解决方法：

1).classes.jar冲突，unity编译时默认包含了classes.jar ，所以删除Plugins/Android/libs 下的classes.jar

2).检查 Assets\Plugins\Android 下是否有文件重复

3).AndroidManifest.xml 配置问题,

---

我遇到的问题是Assets\Plugins\Android 有重复的jar包，，因为我前后导入了两个sdk到工程里面，导致了有公用的jar包重复了，所有会报错。

解决办法：找到两个Assets\Plugins\Androidsdk 的jar包所在目录，一一对比看一下有没有重复的，

这个像这种只有日期有区别(有的可能是版本号)，，留下最新的就可以了，，，完美解决问题。心情豁然开朗啊，，，
