Why does my alarm not cancel after setting it with thesame request code

Question

I set my alarm this way:

  val broadcastReceiverIntent = Intent(context, AlarmReceiver::class.java)
  broadcastReceiverIntent.putExtra(Constants.ALARM_INTENT_TIME, alarm.time)
  broadcastReceiverIntent.putExtra(Constants.ALARM_INTENT_ID, alarm.id)
  broadcastReceiverIntent.action = System.currentTimeMillis().toString()
  val newPendingIntent = PendingIntent.getBroadcast(
        context,
        alarm.id?:0,
        broadcastReceiverIntent,
        PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT
  )
 //schedule alarm
 val alarmClockInfo = AlarmManager.AlarmClockInfo(calendar.timeInMillis, null)
 alarmManager.setAlarmClock(alarmClockInfo, newPendingIntent)

Then I cancel this way:

val broadcastReceiverIntent = Intent(context, AlarmReceiver::class.java)
val newPendingIntent = PendingIntent.getBroadcast(
        context,
        alarm.id?:0,
        broadcastReceiverIntent,
        PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT
    )

alarmManager.cancel(newPendingIntent)

The alarm still fires off, even when I cancel it. The request code I used to set the alarm is thesame as the one I am using to cancel it.

What could be the cause?

Answer 1

The problem was from:

 broadcastReceiverIntent.action = System.currentTimeMillis().toString()

when setting that alarm.

It appears that that same action is required to cancel the alarm.

Removing that line solved the problem.
