/**
* <p>Notifies an application that HMI conditions have changed for the application. This indicates whether the application
* can speak phrases, display text, perform interactions, receive button presses and events, stream audio, etc. This
* notification will be sent to the application when there has been a change in any one or several of the indicated
* states ({@linkplain HMILevel}, {@linkplain AudioStreamingState} or {@linkplain SystemContext}) for the application</p>
* <p>All three values are, in principle, independent of each other (though there may be some relationships). A value for
* one parameter should not be interpreted from the value of another parameter.</p>
* <p>There are no guarantees about the timeliness or latency of the OnHMIStatus notification. Therefore, for example,
* information such as {@linkplain AudioStreamingState} may not indicate that the audio stream became inaudible to the user
* exactly when the OnHMIStatus notification was received.</p>
