Hi folks, All along, I anticipated using this with Android (and, ideally, also iOS). The MobileOrg feature set looked great, and the syncing mechanism looked a lot better than sharing Dropbox.
I use git to share my ~/org between two computers (laptop and desktop), using git-remote-gcrypt to store on a server. This makes syncing and resolving conflicts easy (I move between the two throughout the day, so Dropbox is really not a great option here.) Sync integrity -- or at least robust detection of conflicts -- is a must. Encryption is a "very nice to have." Suggestions? Here's what I've found so far: MobileOrg - supports WebDAV storage. Has a robust sync system, integrated with org-mode, in which it seems to be able to write out its changes to a separate file that the computer can integrate. Sounds smart, though I suspect it will require additional hacking to support multiple Android devices. org-mode docs mention encryption for this, but the encryption is not supported by MobileOrg. Also, MobileOrg was last updated 4 years ago and seems to have bitrotted. Orgzly - Supports only Dropbox or local-on-Android storage. The latter is insecure, as it permits any app on the system to read the files. I am really not sure how to integrate this with my workflow. It seems like potentials for conflicts are extremely high. SyncOrg - Shows some promise, but couldn't even test locally due to the folder selection screen not working for the "External/Local Only." Suspect it's trying to do something insecure as well, or doesn't work on Oreo? ssh support seems to actually be ssh+git, which is nice - except that it's unencrypted. doh. The documentation made no mention of resolving conflicts. https://github.com/wizmer/syncorg/wiki/FAQ seems to suggest it uses the old MobileOrg push/pull in org-mode, but I can't see how that possibly works well with Git. I suspect that FAQ to be totally obsolete, because it also talks about a Dropbox synchronizer that SyncOrg doesn't even have. I could use this if I drop git-remote-gcrypt, I hope. MobileOrg-NG - Last updated in 2012. Didn't really look past that.
