AudioPlayerUtility beginner issue

[archerabi]

Hello,
I am writing a simple media player and i've used the audioplayerutility classes as shown here
http://wiki.forum.nokia.com/index.ph...ng_audio_files

My main class is

_LIT(KFile,"C:/astand.wav");
//  Global Variables

LOCAL_D CConsoleBase* console; // write all messages to this


//  Local Functions

LOCAL_C void MainL()
	{
	//
	// add your program code here, example code below
	//
	
	CPlayerUtility *player;
	player=  CPlayerUtility::NewL(KFile);
	console->Write(_L("Hello, world!\n"));
	
	}

The MapcInitComplete function isn't called at all.
Any ideas?

Abhi.

CPlayerUtility *player; is local for the function, so you should actually make a class, that derives from CBase and from the interface required for the player, and have the player as a member variable for the class.

@symbianyucca
i guess that's what i did ,didn't i?

The playerutility class inherits from CBASE and the interface and has the CMdaAudioUtilityPLayer as its class variable.
Also is the path to the file correct...is it C:/astand.wav or C:\astand.wav or C:\\astand.wav.

[symbianyucca]

you have CPlayerUtility *player; declared in a MainL() function, so it is not as you are now descriping it, either you have mis understood something, or your code
sample with first post is incorrect.

When i played in console it didn't work but when i played it in a GUI app it worked!
