Android6.0新引进了全新的权限管理方式，不了解的可以先去查看

Android 6.0 新特性之 RunTime Permissions ：http://blog.csdn.net/u011068996/article/details/50517869

本文主要讲解在android6.0中的动态权限管理的解决方案。

在6.0中需要动态获取权限，而在动态获取权限的时候，默认提示框包含不在提示按钮，一旦用户勾选了不在提示，那么默认的系统提示框就不会再出现，因此我们需要自定义系统提示框。

在Api 23中, 权限需要动态获取, 核心权限必须满足. 标准流程: 



下面我们以读取文件权限为例，演示对动态权限获取的解决方案.

1 、 权限检测工具
