Tizen Developers

Hi,

In Tizen an application can be launched by the user from the Launcher or by another application.

An application can be launched by the user from the launcher or by another application through the application control.
The application control launch request describes either an action to be performed by other applications, or the results
of that action.
See link https://developer.tizen.org/ko/development/guides/native-application/application-management/application-controls?langredirect=1
for "Launch Types".

See some previous post also for insight
https://developer.tizen.org/zh-hans/forums/native-application-development/it-possible-make-custom-launcher-application-on-tizen-2.3?langswitch=zh-hans

Hope it will help.
