Mark--
I'm binding to the service and then starting it so that I can get
the notification of the propertyUpdate.
As far as dssShow not being assigned to:
in bindService(i, mConnection, Context.BIND_AUTO_CREATE);
mConnection is an instance of a ServiceConnection object that has a
onServiceConnected handler which is supposed to fire when the
connection is made (in my understanding). That code is copy pasted
from the SDK with minor tweeks:
protected ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className,
IBinder service) {
// This is called when the connection with the service has been
// established, giving us the service object we can use to
// interact with the service. Because we have bound to a explicit
// service that we know is running in our own process, we can
// cast its IBinder to a concrete class and directly access it.
dssShow = (DownloadShowsService)
((DownloadShowsService.LocalBinder)service).getService();
}
public void onServiceDisconnected(ComponentName className) {
// This is called when the connection with the service has been
// unexpectedly disconnected -- that is, its process crashed.
// Because it is running in our same process, we should never
// see this happen.
dssShow = null;
}
};

Every 5 minutes you spend writing code in a new language is more
useful than 5 hours reading blog posts about how great the language
is.
