Android Installation - openhab/org.openhab.ui.habmin GitHub Wiki

The release also contains an Android package (apk file) - this can be downloaded to an Android device - no further installation is required in openhab (other than the JAR files mentioned above). When the app starts, it should ask you for server and login credentials.

I'm still trying to get the reconnection sorted, so it's possible that you may need to log out, and log on to get the connect back when you start again. Please feel free to open an issue and report your findings.
