Multiple Repeating Alarm using Alarm Manager

Question

I'm working on a small project, which is a pill reminder app.

in my Setting Preference i have code like this

SettingsPreference.kt

.....

override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
        setPreferencesFromResource(R.xml.setting_preference, rootKey) 

.....

notificationPreference?.setOnPreferenceChangeListener { preference, newValue ->
            alarmReceiver = AlarmReceiver()
            newValue?.let {
                when (it as Boolean) {
                    true -> {
                        alarmReceiver.setMedicineScheduleAlarm(requireContext(), "21:42", "Test1")
                        alarmReceiver.setMedicineScheduleAlarm(requireContext(), "21:43", "Test2")
                    }
                    false -> {
                        //Cancel Alarm
                    }
                }
            }
            true
        }

}

and in my AlarmReceiver.kt

class AlarmReceiver : BroadcastReceiver() {

.....

    override fun onReceive(context: Context, intent: Intent) {
        val medicineName = intent.getStringExtra(EXTRA_MEDICINE_NAME)
        val notifId = NOTIF_ID

        if (medicineName != null) {
            showAlarmNotification(context, notifId)
        }
    }

    fun setMedicineScheduleAlarm(
        context: Context,
        time: String,
        medicineName: String
    ) {
        val timeArray = time.split(":".toRegex()).dropLastWhile { it.isEmpty() }.toTypedArray()
        val alarmID =
            Integer.parseInt(timeArray[0]) + Integer.parseInt(timeArray[0]) + System.currentTimeMillis()
                .toInt()

        val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
        val intent = Intent(context, AlarmReceiver::class.java)
        intent.putExtra(EXTRA_MEDICINE_NAME, medicineName)


        val calendar = Calendar.getInstance()
        calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(timeArray[0]))
        calendar.set(Calendar.MINUTE, Integer.parseInt(timeArray[1]))
        calendar.set(Calendar.SECOND, 0)

        val pendingIntent =
            PendingIntent.getBroadcast(
                context,
                alarmID,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT
            )
        alarmManager.setRepeating(
            AlarmManager.RTC_WAKEUP,
            calendar.timeInMillis,
            AlarmManager.INTERVAL_DAY,
            pendingIntent
        )
        Log.d("STATUS", "ALARM SET")
    }

    private fun showAlarmNotification(
        context: Context,
        notifId: Int
    ) {
        val channelId = "Channel_1"
        val channelName = "AlarmManagerChannel"

        val notificationManager =
            context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
        val alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
        val builder = NotificationCompat.Builder(context, channelId)
            .setSmallIcon(R.drawable.ic_notification_secondary_solid)
            .setContentTitle("time to take medicine")
            .setContentText("Don't forget to take your medicine")
            .setColor(ContextCompat.getColor(context, android.R.color.transparent))
            .setVibrate(longArrayOf(1000, 1000, 1000, 1000, 1000))
            .setSound(alarmSound)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val channel = NotificationChannel(
                channelId,
                channelName,
                NotificationManager.IMPORTANCE_DEFAULT
            )
            channel.enableVibration(true)
            channel.vibrationPattern = longArrayOf(1000, 1000, 1000, 1000, 1000)
            builder.setChannelId(channelId)
            notificationManager.createNotificationChannel(channel)
        }

        val notification = builder.build()
        notificationManager.notify(notifId, notification)
    }
}

the above code runs normally but, only the last alarm works and runs the notification. what is wrong with my code? even the requestCode for pending intent is different for each alarm

thanks in advance
