IPv6Droid is an Android client for IPv6 tunnels, in order to bring IPv6 support to Android mobile devices on networks that do not support IPv6 (specifically, all mobile networks in Germany at the time of writing).
The project has moved to github.com.
Mikrodroid lets you to manage MikroTik routers from an Android device. It is primarily aimed at power users who are used to doing things from the command line.
The application is currently in Alpha.
The initial goal is have to complete read-only access to all the menus and values on a typical MikroTik router.
In order to use the application you have to download the source code and get it working. I use Eclipse.
If you have any problems with the application please log a ticket.
