git-annex is now available for Android. This includes the git-annex assistant, for easy syncing between your Android and other devices. You do not need to root your Android to use git-annex.
Android installation instructions
When you run the git-annex Android app, two windows will open. The first is a terminal window, and the second is a web browser showing the git-annex webapp.
closing and reopening the webapp
The webapp does not need to be left open after you've set up your
repository. As long as the terminal window is left open, git-annex will
remain running and sync your files. To re-open the webapp after closing it,
use the 
icon in the terminal window.
starting git-annex
The app is not currently automatically started on boot, so you will need to manually open it to keep your files in sync. You do not need to leave the app running all the time, though. It will sync back up automatically when started.
stopping git-annex
Simply close the terminal window to stop git-annex from running.
using the command line
If you prefer to use git-annex at the command line, you can do so using the
terminal. A fairly full set of tools is provided, including git, ssh,
rsync, and gpg.
To prevent the webapp from being automatically started
when a terminal window opens, go into the terminal preferences, to "Initial
Command", and clear out the default git annex webapp setting.
Or, if you'd like to run the assistant automatically, but not open the
webapp, change the "Initial Command" to: git annex assistant --autostart
using from adb shell
To set up the git-annex environment from within adb shell, run:
/data/data/ga.androidterm/runshell
This will launch a shell that has git-annex, git, etc in PATH.
@frioux the webapp has a "ssh server" option that will set up a ssh key and use it for passwordless data transfer to a ssh server.
The openssh included in the git-annex app fully supports everything you can usually do with ssh keys, so you can also set this up by hand.
If you are experiencing a problem using git-annex on Android, please examine the list of bugs and add a new, detailed bug report if no-one has reported the problem. If you are not sure if you have a bug, or need help in filing a good bug report, ask for help in the forum.
I have moved to oldcomments a lot of old comments about problems that may be fixed or not (hard to tell without a bug report!) " This page cannot scale to handle every bug report that someone wants to paste into it.
Hallo,
how can I use the app with public/private keys for SSH. Where can I add them?
Thanks
Mebus
@mebus : You can put your SSH keys here :
/sdcard/git-annex.home/.ssh/id_rsa
/sdcard/git-annex.home/.ssh/id_rsa.pub
How is this designed to work in the contact of Androids crap permissions?
I generated an rsa keypair and added them to /sd/ga-h/.ssh, yet they were overwritten. I couldn't access my annexes located on github. I couldn't login to google talk, as instructed by the web app.
Thanks for letting me know about gitlab supporting git-annex.
Hello, I have installed the APK on Android N. However, the assistant doesn't launch, gives an error on terminal: "Cannot link executive git-annex."
What is causing this? Please help.
The same here on Android 8.1.0. likely because .app was build for 5, but there is nothing newer offered on Android downloads. So the Android Port is abandoned overall?
