Scheduling local notifications in Android apps involves using the NotificationManager and AlarmManager classes. Here's a breakdown of the process:
Create a PendingIntent: This is crucial. A PendingIntent acts as a proxy for an Intent, allowing the system to trigger it at a later time. You'll create an Intent that points to a BroadcastReceiver (or an Activity, but BroadcastReceiver is generally preferred for background tasks). This Intent will contain any data needed by the notification (title, message, etc.). The PendingIntent is then created using PendingIntent.getBroadcast().
Set the Alarm: The AlarmManager is used to schedule the PendingIntent. You'll use methods like setExactAndAllowWhileIdle() or setExact() to specify the exact time or a time window for the notification. The choice depends on the level of precision required and Android version compatibility.
Create the Notification: Use NotificationCompat.Builder to construct the notification. This includes setting the title, text, icon, and other visual elements. NotificationChannel is necessary for Android Oreo (API 26) and above.
Trigger the Notification: When the AlarmManager triggers the PendingIntent, it fires the BroadcastReceiver. The BroadcastReceiver then uses the NotificationManager to display the notification.
Code Example (Kotlin):
val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val intent = Intent(this, NotificationReceiver::class.java).apply {
putExtra("notificationTitle", "My Notification")
putExtra("notificationBody", "This is a test notification")
}
val pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT)
val alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
val triggerTime = System.currentTimeMillis() + 60000 // 1 minute from now
alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, triggerTime, pendingIntent)
