The mobile application needs access to a file directory on
a server162 to interact with Emacs. Pass its location through
the org-mobile-directory
variable. If you can mount that directory
locally just set the variable to point to that directory:
(setq org-mobile-directory "~/orgmobile/")
Alternatively, by using TRAMP (see TRAMP User Manual),
org-mobile-directory
may point to a remote directory accessible
through, for example, SSH, SCP, or DAVS:
(setq org-mobile-directory "/davs:user@remote.host:/org/webdav/")
With a public server, consider encrypting the files. Org also
requires OpenSSL installed on the local computer. To turn on
encryption, set the same password in the mobile application and in
Emacs. Set the password in the variable
org-mobile-use-encryption
163. Note that even after the mobile application encrypts the
file contents, the file name remains visible on the file systems of
the local computer, the server, and the mobile device.
