Android File Sync Assistant is a small Android app without a user interface. When installed, it is detected and run by an Xtralogic app on startup to copy files from a folder accessible by other Android apps, for example by MDM clients, to the app specific external storage location.
Android File Sync Assistant app declares android.permission.MANAGE_EXTERNAL_STORAGE permission. This permission needs to be assigned using MDM, or the system will interactively ask user for the permission the first time the companion app runs.
If a source folder contains other folders, they are not copied.
