RE: StateChanged device

["Jos Collin-ERS,HCLTech" <joscollin hcl com>]

Dan,

Thanks for the suggestion. I have decided to monitor the device's signals for state.  I have found that there is a org.freedesktop.NetworkManager.Device.Statechanged signal and I have written a handler for it. 

But there is a related issue. As you can see the Device.java is inside the package org.freedesktop.NetworkManager. When I include the stub in my code, Device.java shows an error "The package org.freedesktop.NetworkManager collides with a type". The reason is there is a NetworkManager.java in the same directory of org.thales.NetworkManager package. 

If I change the package name or the class name then the signal reception won't work. I cannot even change the package name from NetworkManager to networkmanager. If I do that, I won't get the signals. So please suggest a solution.

Thanks,
Jos Collin

The StateChanged signal is an "global" signal that emits the core NM
state.  That state is a composite of the state of all device managed by
NM.  The best approach here is probably to just query NM for the device
you care about, and monitor the device's signals for state.  Or, you can
listed for the global StateChanged signal, then ask NM for each device
object and each device's state.  If you end goal is simply to figure out
whether a specific network interface is 'connected'  or not, I'd go for
the first option: listen for state on the device(s) you care about.  The
"global" bits are more for email/chat/web clients that just want to know
"am I online".

http://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/python

has some python examples, including 'nm-state.py' which explicitly
queries each device's state.  You'd basically do that when you get the
StateChanged signal.
