Log.e("dbCal Alarm","first"+dbcal.getTime());
if(!dbcal.getTime().before(currentcal.getTime())){
    uniqueno++;
    alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(SampledateActivity.this,AlarmReceiver.class);
    PendingIntent pi = PendingIntent.getBroadcast(SampledateActivity.this, uniqueno, intent, 0);
    alarmManager.set(AlarmManager.RTC_WAKEUP, dbcal.getTimeInMillis(), pi);
}
for(int k = 1 ; k <= time ;k++){
   Log.e("Entered to alarm","yes");
   dbcal.add(Calendar.HOUR, -24);

Create the PendingIntent with same requestCode that you used to create the PendingInent to start the Alarm.

Intent intentlocal = new Intent(SampledateActivity.this,AlarmReceiver.class);
PendingIntent pilocal = PendingIntent.getBroadcast(SampledateActivity.this,
                                                       uniqueno, intentlocal, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(pilocal);
pilocal.cancel();

I got the solution to my problem. Every time i have refresh my activity. i.e.., when i click on the set alarm button in that i have refresh my activity. so before setting alarms are deleted and newly entered alarms are created.
