New Features

App Launching and Querying

To enable querying and launching of applications from a server endpoint defined by SDL Core and updatable by the policy table, SDL has made the following changes

  • SDL saves state information about connected applications (foreground and inactive) received from a connected application and sent via OnHmiStatus notifications
  • SDL sends an OnSystemRequest with requestType = QUERY_APPS to an application supporting protocol V4 or higher after a successful register app interface if the application is in the foreground
  • SDL sends an OnSystemRequest notification with requestType = QUERY_APPS to applications supporting protocol V4 or higher running on different devices after a successful register app interface if the application is in the foreground
  • SDL does not send OnSystemRequest (QUERY_APPS) to applications in the inactive state
  • Applications which are received by the SystemRequest (QUERY_APPS) are stored and sent to the HMI via UpdateAppList RPC
  • SDL validates the JSON received from the OnSystemRequest(QUERY_APPS) according to the following structure defined by the sdl server
  • When sending UpdateAppList RPCs, applications which are not registered have a greyOut value of true if there is no foregrounded application on the device and false if there is
  • When SDL receives an ActivateApp from the HMI for an application which has not registered, SDL sends an OnSystemRequest(LAUNCH_APP) to an application which is in the foreground
  • SDL defines a timeout for which to wait to receive a register app interface from the requested appId associated with a LAUNCH_APP command
  • If an app does not register within the defined timeout, SDL sends an ActivateApp Response with APPLICATION_NOT_REGISTERED error
  • If SDL receives an OnFindApplications from the HMI, and SDL is connected to an application using protocol V4 or greater, SDL will send an OnSystemRequest with requestType QUERY_APPS
