Overview
This snippet demonstrates how to obtain the number of available sensors on your device (for example, two on the Nokia N95 8GB: accelerometer sensor and rotation sensor).
Note: In order to use the code, you need to install the sensor plugin for your SDK.
MMP file
The following libraries are required:
LIBRARY RRSensorApi.lib
Source file
#include <RRSensorApi.h>RArray<TRRSensorInfo> sensorList;
CleanupClosePushL(sensorList);
// Retrieve list of available sensors
CRRSensorApi::FindSensorsL(sensorList);
// Get number of sensors available
TInt sensorCount = sensorList.Count();
CleanupStack::PopAndDestroy(); // sensorList
Postconditions
The number of available sensors is obtained.
