Since this is the case, you don't need any of the initializations below.
base::TimeDelta defaults to zero.

You could consider passing the default NetworkChangeParams() in the base-class
constructor above with this comment.

+  params.ip_address_online_delay_ = base::TimeDelta::FromMilliseconds(0);
+  params.connection_type_offline_delay_ = base::TimeDelta::FromMilliseconds(0);
+  params.connection_type_online_delay_ = base::TimeDelta::FromMilliseconds(0);
+  return params;
+}

 void NetworkChangeNotifierAndroid::SetConnectionType(int connection_type) {
   base::AutoLock auto_lock(lock_);
   connection_type_ = connection_type;
