Overview

It provides function of creating shortcut. Developers can use the "shortcut_add_to_home" API to create their shortcut to a home screen.

Related Features

This API is related with the following features:

http://tizen.org/feature/shortcut

It is recommended to design feature related codes in your application for reliability.
You can check if a device supports the related features for this API by using System Information, thereby controlling the procedure of your application.
To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.
More details on featuring your application can be found from Feature Element.
