Print the Service's state into the given stream. This gets invoked if you run "adb shell dumpsys activity service <yourservicename>" (note that for this command to work, the service must be running, and you must specify a fully-qualified service name). This is distinct from "dumpsys <servicename>", which only works for named system services and which invokes the Android.OS.BinderConsts.dump(java.io.FileDescriptor, java.lang.String[]) method on the Android.OS.BinderConsts interface registered with ServiceManager.
