On Android, it is unfortunately not possible to synchronize the Obsidian vault on NextCloud.
The official Nextcloud client on Android does not allow to choose the download directory. The download directory is an internal directory of the NextCloud client application. Of course, writing in this internal directory is not allowed. It is not possible to create the Obsidian vault in the download directory of the NextCloud application client. The NextCloud client application only allows one-way synchronization (only upload).
On the computer (Linux Ubuntu, Linux Debian, …, Mac or Windows), the NextCloud client allows to choose the download directory and thus to synchronize in both directions.
