SystemRequest
- Type
- Function
- Sender
- SDL
- Purpose
- Provide the path to a system file that SDL has received from the mobile application
SDL sends SystemRequest to the HMI when SDL receives the SystemRequest RPC from a mobile application.
Behavior
Must
Notify any relevant modules about the location of the file which was transferred.
Note
If the HMI does not respond to SDL's request within a specified timeout period (default of 10 seconds), SDL will return GENERIC_ERROR to the corresponding mobile apps request.
Note
SDL validates all SystemRequests sent from the mobile app and returns DISALLOWED if the app's system request contains a RequestType that is not allowed via Policies.
SDL sends the list of RequestTypes allowed by Policies via OnAppPermissionChanged, UpdateAppList, or OnSystemRequest RPCs.
If the HMI sends OnSystemRequest with a RequestType which is disallowed by the current policy table, SDL will ignore the notification.
If SDL sends a SystemRequest with requestSubType parameter to an older system, it would be rejected by the system with a response of INVALID_DATA.
