Commented startService and stopService

bindService and unbindService are enough
(service live only during the live of activity - it will be destroyed while destroying activity)
Added 'Start Service', 'Stop Service' buttons

The service is created while first run of activity, and it is exist until
click on 'Stop Service'.
Added ongoing notification for service
Removed toasts in ServiceConnection

... and assign null to mBoundService during unbinding.
Added opening of DbusConnection in LocalService
Added logs
Added Notify button to test Dbus
Added adapters on structures created by dbus-java

I don't want to edit the generated code. Unfortunately members' names of
mentioned code are letters (like a, b, c, d, etc.). It is hard to use
structures with that names of members.
Added example with ListView
