Overview

Implementing the camera snap sound in a S60 device.

Description

The most effective way to play the snap sound is to use the CAknKeySoundSystem class. The following code example explains how to implement the feature in your own application:

// myapp.h
#include <aknsoundsystem.h>
const TInt KSnapSoundId = 2;
class MyClass
{
...
private:
CAknKeySoundSystem* iCameraSound;
};
void MyClass::ConstructL()
{
...
iCameraSound =
static_cast<CAknAppUi*>(CEikonEnv::Static()->AppUi())->KeySounds();
if (iCameraSound)
{
TRAPD(error, iCameraSound->AddAppSoundInfoListL(
R_CAMERA_SNAP_SOUND));
if ((error != KErrAlreadyExists) && (error != KErrNone))
{
User::LeaveIfError(error);
}
}
}
void MyClass::PlaySnapSound()
{
iCameraSound->PlaySound(KSnapSoundId);
}
Also add the following code into your application's resource .rss
#define KcameraSoundFile
"Z:\\system\\sounds\\digital\\Camera1a_2_8kHz.wav"
#define KSnapSoundId 2
RESOURCE AVKON_SOUND_INFO_LIST r_camera_snap_sound
{
list =
{
AVKON_SOUND_INFO
{
sid = KSnapSoundId;
priority = 45;
preference = EAknAudioPrefCamera; // defined in avkon.hrh
file = KCameraSoundFile;
}
};
}
