I've built it for Android and currently looking for changes that need to be done to the wrapper. Meanwhilst, I did upgrade the command line using the non-two-dash commands and set STHOMEDIR=... instead of using the --"--home=" parameter which is no longer supported on the commands the wrapper used before.

Feedback:

1. Could the "device-id" please respect the STHOMEDIR variable? I see in the log it is accessing the wrong path on android despite STHOMEDIR being set. This can be reproduced from shell.

2. What is the equivalent to "reset-database"?
   "serve", "--reset-database", "--logflags=0" does not work.

public static final String INDEX_DB_FOLDER = "index-v0.14.0.db";

Does this need to be changed? Also it seems the database is not a seperate directory anymore.

Thanks, I'll note this for review during my next dev session :-).

Update: used in SyncthingService/importConfig, exportConfig

Not sure what these files are, but they also seem to contain the old database path. They also seem to be related to the backup feature.

Folder stopped with filesystemType empty error:
I’ve fixed this by ensuring the wrapper always writes “filesystemType” = “basic” into the config.xml for “folder” tags.
