Attaching my Bash script for illustrative and inspirative purposes.
Note that I am not particularly good at Linux scripting, so it is surely
possible to write in in more elegant or more powerful way. I have just
written it recently, so updates are expected.

Note also if one installs termux, a very good Linux terminal emulator, one
can write wget or curl based Bash scripts for direct download to the final
Android placement, optionally skipping downloads if no update is available,
or if local files are not older than chosen threshold.
Note that it is by default sandboxed, must be explicitly configured to have
access to Android storage.
I use it for BRouter RD5 file updates and Mapsforge compatible maps for
LocusMap.(OpenAndroMaps globally, or osm.paws.cz for middle Europe.), using
iteration overthe script arguments, where each argument is a code for
particular downloadm defined withing tge script.
E.g. argument 0 means an update of my Brouter "homegrid" 5x5deg RD5 file to
be downloaded to
~/storage/shared/Brouter/segments4
