Overview
The
/pps/system/navigator/command object shows the current
display actions of HMI apps. Here's a sample object:
@command
rearview_camera:json:{"action":"pause"}
Note: In the shipped images, the Camera app is the only app for which the display
action is published to this object.
Each line shows an application name, followed by the json data
type, followed by the "action":"value" string
pair. The values for the "action" field can be:
- pause—the app is being told it's in the background, so
it should stop CPU-intensive display tasks (e.g., drawing album cover flows)
- reselect—the app is being told of a special request, so
it should go to its home screen
- resume—the app is being told it's in the foreground, so
it can resume what it was doing before it was paused (e.g., start drawing cover
flows again)
