GKS Phone and Tablet
Add the CarTrader marketplace app to GKS Phone, GKS Tablet or both. The integration registers the app automatically; no separate app resource is needed.
Select the integrations
In jg-usedvehicles/config/config.lua, leave both settings on auto to detect started resources, or select GKS explicitly:
Config.Phone = "gksphone"
Config.Tablet = "gks-tablet"Set either option to "none" if you do not use that device.
Start the resources
Start GKS Phone or GKS Tablet before jg-usedvehicles. Restart jg-usedvehicles after updating the integration files. The app also registers again when a selected GKS resource restarts.
Open CarTrader
Open the app from your phone or tablet. It uses your configured marketplace name and icon. GKS Phone also includes a marketplace home-screen widget.
Phone numbers, calls and notifications use GKS Phone. Both devices support importing photos from the current device's gallery. GKS Tablet does not support taking a new photo from inside CarTrader; use an existing gallery photo instead.
Troubleshooting
If the app is missing, check that the resource names are exactly gksphone and gks-tablet, and that they are started. Keep the supplied marketplace-apps/gksphone/ and marketplace-apps/gks-tablet/ folders when updating Used Vehicles. App registration errors appear in the client console.
The integration files are editable if your GKS installation uses customised exports or gallery tables.
