I'm developing native widget application in Tizen.
I want to update a widget application from UI application.
So, I find widget_service_trigger_update() API to update native widget.
But widget_service_trigger_update() return WIDGET_ERROR_PERMISSION_DENIED error.
Tell me what I did something wrong please.
I found out a something important.
The widget application and UI application should be packaged together.
When UI application which are not packaged with widget application use widget_service_trigger_update(), API return 'WIDGET_ERROR_PERMISSION_DENIED'.
I verified to work well in same package. :)
Good Luck.
