// Create a broadcast receiver to handle the alarm event public class AlarmReceiver : BroadcastReceiver { public override void OnReceive(Context context, Intent intent) { // Handle the alarm event here } } // Create a PendingIntent with the broadcast receiver Intent alarmIntent = new Intent(this, typeof(AlarmReceiver)); PendingIntent pendingIntent = PendingIntent.GetBroadcast(this, 0, alarmIntent, 0); // Set the alarm using the AlarmManager AlarmManager alarmMgr = (AlarmManager)GetSystemService(Context.AlarmService); long triggerTime = SystemClock.ElapsedRealtime() + (10 * 1000); alarmMgr.SetExactAndAllowWhileIdle(AlarmType.ElapsedRealtimeWakeUp, triggerTime, pendingIntent);This code sets an alarm to trigger in 10 seconds and uses the AlarmReceiver class as the broadcast receiver to handle the alarm event. The PendingIntent is created using the GetBroadcast() method with the application context, a unique request code, the Intent for the alarm receiver, and flags for the pending intent. The package library for PendingIntent.GetBroadcast() is Android.Content.
