[tamnv110]

Hi everybody!
I'm making app play file .wav. But i don't listen evething when it run. I was try resolution it, but i don't succses. Help me, please!
I using class CMdaAudioPlayerUtility;
File AudioPlayer.h:

#ifndef AUDIOPLAYER_H_
#define AUDIOPLAYER_H_

#include <e32std.h>
#include <mdaaudiosampleplayer.h>

class CAudioPlayer : public CBase, public MMdaAudioPlayerCallback
	{
public:
	static CAudioPlayer* NewL(const TDesC& aFileName);
	static CAudioPlayer* NewLC(const TDesC& aFileName);
public:
	CAudioPlayer();
	void ConstructL(const TDesC& aFileName);
	virtual ~CAudioPlayer();
public:
	void Play();
	void Stop();
	void Pause();
public:
	void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds& aDuration);
	void MapcPlayComplete(TInt aError);
private:
	CMdaAudioPlayerUtility* iPlay;
	};

File AudioPlayer.cpp:

#include "AudioPlayer.h"
#include <MdaAudioTonePlayer.h>
#include <eikmenup.h>

CAudioPlayer* CAudioPlayer::NewL(const TDesC& aFileName)
	{
	CAudioPlayer* self = NewLC(aFileName);
	CleanupStack::Pop(self);
	return self;
	}

CAudioPlayer* CAudioPlayer::NewLC(const TDesC& aFileName)
	{
	CAudioPlayer* self = new (ELeave) CAudioPlayer();
	CleanupStack::PushL(self);
	self->ConstructL(aFileName);
	return self;
	}
CAudioPlayer::CAudioPlayer()
	{
	// TODO Auto-generated constructor stub

	}

CAudioPlayer::~CAudioPlayer()
	{
	// TODO Auto-generated destructor stub
	if(iPlay)
		{
		iPlay->Stop();
		iPlay->Close();
		}
	delete iPlay;
	}

void
CAudioPlayer::ConstructL(const TDesC &aFileName)
	{
	iPlay = CMdaAudioPlayerUtility::NewFilePlayerL(aFileName, *this);
	}

void CAudioPlayer::Play()
	{
	
	iPlay->Play();
	}

void CAudioPlayer::Pause()
	{
	iPlay->Pause();
	}

void CAudioPlayer::Stop()
	{
	iPlay->Stop();
	}

void
CAudioPlayer::MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds& aDuration)
	{
	if(aError == KErrNone)
		{
		iPlay->SetVolume(iPlay->MaxVolume());
		}
	}

void
CAudioPlayer::MapcPlayComplete(TInt /*aError*/)
	{
	
	}

in file PlayAudioWav.h, i define CAudioPlayer* iPlay;

and in file PlayAudioWav.cpp, i define link file wav:
_LIT(KMusicFile,"VanHoa.wav");
File VanHoa.wav i copied it in C:\S60\devices\S60_3rd_FP2_SDK_v1.1\epoc32\winscw\c\private\E3A12752

void PlayAudioWav::ConstructL(const TRect& aRect)
	{
	// Create a window for this application view
	CreateWindowL();
	SetRect(aRect);
	iPlay = CAudioPlayer::NewL(KMusicFile);
	iPlay->Play();
	ActivateL();
	}

_LIT(KMusicFile,"VanHoa.wav");
File VanHoa.wav i copied it in C:\S60\devices\S60_3rd_FP2_SDK_v1.1\epoc32\winscw\c\private\E3A12752

A clue: that is c:\ of the emulator.
So KMusicFile has to be "c:\\private\\E3A12752\\VanHoa.wav".

I try "c:\\private\\E3A12752\\VanHoa.wav", but it not succses

What happens?
You should check the value of aError in MapcInitComplete, for example in the debugger.

The emulator run, but i don't listen everthing. I try draw image in the screen, it succses, but sounds not play. Sorry, i don't good english.

Sorry, i want display logs like qDebug() in symbian^3 or AppLog in bada, what do i use?

Hi,

There's at least one clear issue in the code:

	iPlay = CAudioPlayer::NewL(KMusicFile);
	iPlay->Play();

You're calling iPlay->Play() right away after instantiating the CAudioPlayer. The CMdaAudioPlayerUtility instance created in CAudioPlayer::ConstructL will not yet be ready for use at this point, you should wait for MapcInitComplete callback before trying to play sounds.

Sorry, i want display logs like qDebug() in symbian^3 or AppLog in bada, what do i use?

Try RDebug::Print:

Thank TongMuan very much. I think symbian c++ verry diffirent.

[tamnv110]

I try call iPlay->Play() in MapcInitComplete, but it not play file audio. I need an example full, can you help me.
