I've tried to follow this Stack Overflow post for setting a notification for future dates but something isn't working as the notification never comes. Let me know if more information is needed
class AddReminderActivity : AppCompatActivity() {
val saveButton: Button = findViewById(R.id.reminder_save_button)
saveButton.setOnClickListener {
val editText: EditText = findViewById(R.id.reminder_title)
val reminderTitle = editText.text.toString()
val intent = Intent(this, Receiver::class.java)
intent.putExtra("reminderTitle", reminderTitle)
val pendingIntent = PendingIntent.getBroadcast(this, 1, intent, PendingIntent.FLAG_IMMUTABLE)
val am: AlarmManager = getSystemService(ALARM_SERVICE) as AlarmManager
am.set(AlarmManager.RTC_WAKEUP, combinedCal.timeInMillis, pendingIntent)
}
}
class Receiver : Service() {
lateinit var reminderTitle: String
override fun onBind(intent: Intent): IBinder? {
return null
}
override fun onCreate() {
val intent = Intent(this, AddReminderActivity::class.java)
val pattern = longArrayOf(0, 300, 0)
val pi = PendingIntent.getActivity(this, 1234, intent, PendingIntent.FLAG_IMMUTABLE)
reminderTitle = intent.getStringExtra("reminderTitle").toString()
val builder = NotificationCompat.Builder(this)
.setContentTitle(reminderTitle)
.setVibrate(pattern).setAutoCancel(true)
builder.setContentIntent(pi)
builder.setDefaults(Notification.DEFAULT_SOUND)
builder.setAutoCancel(true)
val notificationManager =
this.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(1234, builder.build())
}
}
