+ * clients may supply a {@link ServiceListener}, which is informed when the ServiceMonitor connects
+ * and disconnects from a service. This allows clients to bring a bound service back into a known
+ * state on connection, and then run binder operations from there. In order to help clients
+ * accomplish this, ServiceMonitor guarantees that {@link BinderOperation}s and the
+ * {@link ServiceListener} will always be run on the same thread, so that strong ordering guarantees
+ * can be established between them.
+ *
+ * There is never any guarantee of whether a ServiceMonitor is currently connected to a service, and
+ * whether any particular {@link BinderOperation} will succeed. Clients must ensure they do not rely
+ * on this, and instead use {@link ServiceListener} notifications as necessary to recover from
