I am looking to block a few URLs from an android device... however, I would like to take an extra level of security and password protect the hosts file.
I think I can do that with ES File Explorer by the looks of it? https://www.howtogeek.com/221582/19-things-you-didnt-know-androids-es-file-explorer-can-do/amp/
I'm wondering, if I encrypt the hosts file but then uninstall ES File Explorer, will the hosts file stay encrypted?
Or if not, is there another way to achieve this?
