Apps create apk to edit system files

[pannam]

Hi,
the flashable zips usually replace some system files. I want to create an apk that can do exactly what those zips do, without booting into recovery.

any pointers ?

For a non-rooted phone? You can't. The apk has only the permissions a regular user has, and that doesn't include changing system files.
