|
The Haptic API provides functions to control vibration.
Required Header
#include <device/haptic.h>
Overview
The Haptic API provides the way to control vibration functionality of a device. It allows the management of the device's vibrator parameters, such as the vibration count and level.
Related Features
This API is related with the following features:
- http://tizen.org/feature/feedback.vibration
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 description.
