Introduction

This article shows you how to set your own song to clock alarm and play when the alarm expires. Most of the code are common and are taken from the Wiki, but the extra thing that is being added is setting own audio file to the alarm server. This code has been tested on 5th edition and S^3 devices, but also expected to work on 3rd edition too.

MMP

LIBRARY        centralrepository.lib alarmclient.lib alarmshared.lib apgrfx.lib
CAPABILITY	  WriteDeviceData

Header Files

If the header files are not in the SDK , then get it from API Plug-in

#include <clockdomaincrkeys.h>
#include <centralrepository.h> // Headers Used for CRepository
#include <ASShdDefs.h>
#include <calendarinternalcrkeys.h>
//check clock alarm
#include <almconst.h>
#include <ASCliSession.h>    // For RASCliSession.
#include <ASShdAlarm.h>      // For TASShdAlarm.
// System Includes
#include <apgcli.h> // for RApaLsSession
#include <apacmdln.h> // for CApaCommandLine
class CRepository;
class RASCliSession;
 
const TInt KWakeupAlarmFlagIndex = 0;   // wakeup alarm	
            CRepository* iRepository;// = CRepository::NewL( KCRUidClockApp );
	    TInt iErrCode;
	    TInt iVal;  
	    TBuf<200> iDispVal;
             RASCliSession iCliSession;
	     TASShdAlarm alarm;

ConstructL()

          iCliSession.Connect();
	  iRepository = CRepository::NewL( KCRUidClockApp );// alarm clock

Destructor

if(iRepository)
		{
	delete iRepository;
	iRepository =NULL;
 
		}
 
	iCliSession.Close();

Check Alarm Type

check the alarm type with the UID because it could be a clock or a calendar alarm

RArray<TAlarmId> ids;
	// Get List of all alarm
	iCliSession.GetAlarmIdListL(ids);
	TASShdAlarm alarm;
	for (TInt i = 0; i < ids.Count(); i++)
		{
		TInt err(KErrNone);
		err = iCliSession.GetAlarmDetails(ids[i], alarm);
		if ((!err))
			{
			if (alarm.Category().iUid == KAlarmClockOne.iUid)
				{
				CEikonEnv::InfoWinL(_L("Clock Alarm"), alarm.Message());
				}
			else
				{
				CEikonEnv::InfoWinL(_L("Not Clock Alarm"), alarm.Message());
				}
			}
		}

Check Active Song of the Alarm

you can check the song that is being set in the alarm server

iErrCode = iRepository->Get(KClockAppSoundFile, iDispVal);
			if (iErrCode == KErrNone)
				{
			iEikonEnv->AlertWin(_L("Song: "), iDispVal);
				}
			else
				{
				iDispVal.Num(iErrCode);
				iEikonEnv->AlertWin(_L("error"), iDispVal);
				}

Set Own song to Alarm

This code helps you to add your own audio file to the alarm server.

_LIT(KSampleAudio,"C:\\system\\E829D5AB\\sample.wav");
iErrCode = iRepository->Get(KClockAppSoundFile, iDispVal);
			if (iErrCode == KErrNone)
				{
				iRepository->Set(KClockAppSoundFile, KSampleAudio);
				}
			else
				{
				iDispVal.Num(iErrCode);
				iEikonEnv->AlertWin(_L("error"), iDispVal);
				}

Add Aalrm to the Alarm Server

Now add alarm to the alarm server and this is a wakeup alarm.

TAlarmCategory alarmCategory = KAlarmClockOne;//KASCliCategoryClock;
	alarm.Category()=alarmCategory;
	_LIT(KAlarmMessage, "RingingAlarm");
	alarm.Message() = KAlarmMessage;
 
	alarm.RepeatDefinition() = EAlarmRepeatDefintionRepeatDaily; // alarm daily
	alarm.ClientFlags().Set(KWakeupAlarmFlagIndex);// wake up alarm
	alarm.NextDueTime().HomeTime();
	//EAlarmRepeatDefintionRepeatDailyOnGivenDays
	alarm.NextDueTime() += TTimeIntervalMinutes(1);//Seconds(61);
	iCliSession.AlarmAdd(alarm);

Update alarm time

We have updated the alarm time but need to find Alarm Message in the alarm server. This is to be done so that we don't delete any other alarm of same or different type from the server.

RArray<TAlarmId> ids;
		// Get List of all alarm
		iCliSession.GetAlarmIdListL(ids);
		TASShdAlarm alarm;
		for (TInt i = 0; i < ids.Count(); i++)
			{
			TInt err(KErrNone);
			err = iCliSession.GetAlarmDetails(ids[i], alarm);
			if ((!err))
				{
				if (alarm.Category().iUid == KAlarmClockOne.iUid)
					{
				iCliSession.AlarmDeleteByCategory(alarm.Category(),EAllAlarms);
					//CEikonEnv::InfoWinL(_L("Clock Alarm"), alarm.Message());
					if(alarm.Message().Compare(_L("RingingAlarm"))==0)
						{
 
				         	//iCliSession.AlarmDeleteByCategory(alarm.Category(),EAllAlarms);
				         	iCliSession.AlarmDelete(alarm.Id()); // delete clock alarm by its ID
				         	CEikonEnv::InfoWinL(_L("Clock Alarm"),_L("Set"));
						}
					}
				else
					{
 
					//CEikonEnv::InfoWinL(_L("Not Clock Alarm"), alarm.Message());
				//iCliSession.AlarmDeleteByCategory(alarm.Category(),EAllAlarms);  //delete other alarm
					}
				}
			}
