Description

Native Android binaries of the Unison File Synchronizer - a powerful cross-platform file synchronization tool.

This app only deploys the Android binaries of Unison, Dropbear SSH and OpenSSH; and displays a quick howto.
Unison must be used manually from the command line, and root is required.

(For an Android GUI for Unison, check UnisonSync on GooglePlay.)

BACKGROUND
Unison is a powerful cross-platform file synchronization tool available on Linux, OS X, Windows, etc. Unison takes two roots, that can be on different machines and can be modified separately, and brings them up to date by smartly propagating the changes between the roots.

The key features of Unison are:
- Synchronization between different platforms
- Handles simultaneous updates to both roots
- Smart and safe: Unison resolves most simultaneous changes on both roots automatically, and prompts the user for input if it cannot determine the copy to propagate
- Synchronization to a server over SSH: any machine with an SSH server and Unison can act as server
- Resilient: handles interruptions, network disconnections, etc.
- Bandwidth efficient: the data is transfered by a compressed protocol similar to rsync, and only modified files (or parts of files) are transferred.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

User's Reivew

5 ★The "Lost connection with the server" error means unison is having trouble using ssh to contact the server. In my case I had my own ssh executable I was trying to use, and SELinux was preventing applications installed in /data (including unison) from running system apps. Moving the unison executables into /system/xbin fixed it. Configuring SELinux to let unison run ssh also would have worked, and so would using socket mode with a unison server. The lost connection error is very generic - it just means something went wrong using ssh to run unison on the server. I diagnosed it by setting unison's sshcmd to a script I wrote to run env and echo $*. The idea was to see the environment variables and command line parameters ssh was seeing, duplicate it manually, and where it failed. But my script wasn't called, which pointed to SELinux being the problem. Now that it's fixed, unison is working very well.
2 ★Too dated. Does not work on newer versions of Android.
1 ★Simply doesn't work. I get the unhelpful lost connection message every time, with no clue how to fix it.
1 ★Pfff. No help from the developer. Any other 2-way sync software to sync a large home?
5 ★Works just as well as the computer version: perfectly. Every bit as fast and efficient.
5 ★I so appreciate being able to sync with my laptop.
5 ★Thank you for making this app :)
5 ★Excellent job.
5 ★Just the app I was always looking for.
1 ★Tool doesn't give information on which port unison s listening and which user I have to make use when connecting.
1 ★This doesn't do anything but take you to the paid app download page.
1 ★Requires root
