I am trying to make a file manager using B4A
From version 10 of Android, access to the Android memory directories is very limited, for non-rooted devices
However, I see that several file managers found on the Play Store are able to view the contents of many Android program / data directories, even those 'external' to the app that is running
The question is: how to make the B4A app read/write access to all directories/files of the operating system?
If this is not possible for non-root devices, what permissions do you need to have access to as many directories/files as possible?
