二、解决方案

在 Android 11 之后 , 不能使用 File 进行文件操作 , 需要使用 MediaStore 进行文件操作 ,

MediaStore 的如下内部类 Files , Images , Downloads , Audio , Video , 负责相应目录的文件操作 , 分别对应外置存储中的 Document , Pictures , Download , Music , Movies 目录 ;

对应格式的文件 , 只能放在特定的目录中 ;

文件存储类型限制 : 文件一旦放错位置 , 就会抛异常 ;

  • 专门存储 图片文件 的目录 Pictures , 只能存放图片 , 不能存放其它类型文件 ,
  • 专门存储 视频文件 的目录 Movies , 只能存视频文件 ;
  • 专门存储音频文件的目录 Music , 只能存储音频文件 ;
  • 专门存储文档文件的目录 Document , 只能存储文档相关文件 ;
  • Download 目录可以放置任何类型的文件 ;
