I don't know if this is the best way but I've done it so:
1. "Daemon" is basically a QCoreApplication which has dbus-interface
2. It's invoked by sending first dbus message to it (I use session for this)
3. It does not have systemd dependecy so it needs to take care of it's
own living. I use a ShMem block so I need to make sure that block is
available when this daemon wakes up
4. UI application is just a QML/C++ app that has interface to dbus
In a nutshell you need
1. app based on QCoreApplication
2. dbus service and interface definition
3. take care of the "daemon's" lifecycle

Hi,
I'm trying to run one of my harmattan apps using Sailfish SDK. My app consists
of a daemon and a UI app which communicate with each other. I couldn't find any
info on how to create daemons on Sailfish/nemo. Any pointers?
In general daemons are run using systemd. We use systemd user sessions.
This typically makes writing a daemon easier as it does not need to worry about
forking or respawning.
Lots of detail here:
