Find files not accessed in last x days on android

Question

I've an android app that writes files to the disk frequently. I want to write a cleanup module that would find files that are not accessed in last x days and report/clean them up.

Since the filesystem would generally be noatime. I was wondering what would be a nice design to go ahead with this?

Answer 1

I needed something similar, but I found out that android doesnt have implemented "time of last access", so I created database where I save access time when user opens the file. Maybe you can use something similar if user is opening files through your app.

我相信您可以使用stat命令来实现所需的功能-您可以在此处查看示例： Android中任何文件的上次访问时间
