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?

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.

For my use, going back and tracking every file would be difficult. Besides I'm looking for a solution on cleaning up already exising files. – atuljangra Feb 06 '17 at 20:50

I believe you can achieve what you need using the stat command - you can look here for an example: Last Accessed Time of any file in Android

I think that doesn't work on filesystems where no access time is stored. – atuljangra Feb 06 '17 at 20:50
