Android 6.0 - 动态权限管理的解决方案
Android 6.0版本(Api 23)推出了很多新的特性, 大幅提升了用户体验, 同时也为程序员带来新的负担.
动态权限管理就是这样, 一方面让用户更加容易的控制自己的隐私, 一方面需要重新适配应用权限. 时代总是不断发展, 程序总是以人为本, 让我们为应用添加动态权限管理吧! 这里提供了一个非常不错的解决方案, 提供源码, 项目可以直接使用.
Android系统包含默认的授权提示框, 但是我们仍需要设置自己的页面. 原因是系统提供的授权框, 会有不再提示的选项. 如果用户选择, 则无法触发授权提示. 使用自定义的提示页面, 可以给予用户手动修改授权的指导.
本文示例的GitHub下载地址
在Api 23中, 权限需要动态获取, 核心权限必须满足. 标准流程:
如果用户点击, 不再提示, 则系统授权弹窗将不会弹出. 流程变为:
流程就这些, 让我们看看代码吧.
<code class="xml"><span class="hljs-comment" style="color: rgb(136, 0, 0);"><!--危险权限--></span>

危险权限必须要授权, 一般权限不需要.

3. 授权页
授权页, 首先使用系统默认的授权页, 当用户拒绝时, 指导用户手动设置, 当用户再次操作失败后, 返回继续提示. 用户手动退出授权页时, 给使用页发送授权失败的通知.
