permissionmanager's Introduction

android6.0之前,当我们需要使用到存储权限时(如创建目录,保存图片等操作),我们只需要在AndroidManifest.xml中申明权限即可

但是在android6.0之后除了在AndroidManifest.xml中申明权限之外,我们还需要在代码中动态申请权限,让用户确认才可以

这对于刚刚接触android6.0的开发者来说就是一个坑

有时候在之前的手机上正常运行的应用,在新手机上就出现各种莫名其妙的问题,因此为了不让更多人掉坑里,我这里分享一下我权限申请的步骤。

这里面的工具相关的代码也是参考之前github上别人分享的,不过他的代码太过复杂,所以我这里抽取出来并且以实际demo的形式来演示如何动态申请权限,供大家参考。

导入包:

implementation 'com.zengyu:permission:1.0.0'

使用步骤:

  1. 定义PermissionHelper变量。
  2. 在需要检查权限的地方调用doPermissionCheck()方法。
  3. 实现OnPermissionCallback回调接口。
  4. 在实现的回调方法里面做各自的事情。具体可以看注释。也可以通过添加日志的方式来观察。
