Class OnHMIStatus





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 (HMILevel, AudioStreamingState or SystemContext) for the application

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.

There are no guarantees about the timeliness or latency of the OnHMIStatus notification. Therefore, for example, information such as AudioStreamingState may not indicate that the audio stream became inaudible to the user exactly when the OnHMIStatus notification was received.

Parameter List:

Name Type Description SmartDeviceLink Ver Available
hmiLevel HMILevel The current HMI Level in effect for the application. SmartDeviceLink 1.0
audioStreamingState AudioStreamingState Current state of audio streaming for the application. When this parameter has a value of NOT_AUDIBLE, the application must stop streaming audio to SDL. Informs app whether any currently streaming audio is audible to user (AUDIBLE) or not (NOT_AUDIBLE). A value of NOT_AUDIBLE means that either the application's audio will not be audible to the user, or that the application's audio should not be audible to the user (i.e. some other application on the mobile device may be streaming audio and the application's audio would be blended with that other audio). SmartDeviceLink 1.0
videoStreamingState VideoStreamingState If it is NOT_STREAMABLE, the app must stop streaming video to SDL Core(stop service). SmartDeviceLink 5.0
systemContext SystemContext Indicates that a user-initiated interaction is in-progress (VRSESSION or MENU), or not (MAIN) SmartDeviceLink 1.0
