NOTE: If you are new to AlarmManager, you might want to refer to Android AlarmManager: Setup Repeating Alarm (Daily Reminder).
For multiple alarms, use different requestCode for PendingIntent.getBroadcast.
For parameters passing, use Intent.putExtra.
class ReminderReceiver : BroadcastReceiver() { companion object { private const val PARAM_NAME = "name" private const val REQUEST_TIMER1 = 1 private const val REQUEST_TIMER2 = 2 fun getIntent(context: Context, requestCode: Int, name: String? = null): PendingIntent? { val intent = Intent(context, ReminderReceiver::class.java) intent.putExtra(PARAM_NAME, name) return PendingIntent.getBroadcast(context, requestCode, intent, PendingIntent.FLAG_CANCEL_CURRENT) } fun startAlarm1(context: Context) { Timber.d("startAlarm1") val pendingIntent = getIntent(context, REQUEST_TIMER1, "Timer 01") val alarm = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager // start immediately, the once every 2 minutes val intervalMillis = 2L * 60L * 1_000L val triggerAtMillis = System.currentTimeMillis() alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, triggerAtMillis, intervalMillis, pendingIntent) } fun startAlarm2(context: Context) { Timber.d("startAlarm2") val pendingIntent = getIntent(context, REQUEST_TIMER2, "Timer 02") val alarm = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager // start once every 1 minute val intervalMillis = 1L * 60L * 1_000L val triggerAtMillis = System.currentTimeMillis() + intervalMillis alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, triggerAtMillis, intervalMillis, pendingIntent) } fun cancelAlarm(context: Context) { Timber.d("stopAlarm1+2") val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager getIntent(context, REQUEST_TIMER1).apply { alarmManager.cancel(this) } getIntent(context, REQUEST_TIMER2).apply { alarmManager.cancel(this) } } } override fun onReceive(context: Context, intent: Intent) { val name = intent.getStringExtra(PARAM_NAME) Timber.d("onReceive, name=$name") Toast.makeText(context, name, Toast.LENGTH_LONG).show() }}Usage
