To create a wake-up program in mcdvoice Kotlin for Android, follow these steps:

  1. Create a BroadcastReceiver to handle notifications.

  2. Use AlarmManager to schedule notifications at specific times.

  3. Schedule repeating alarms to run daily.

  4. Handle notification messages to display to the user.

Here’s a sample code to get you started:

Kotlin

// AlarmReceiver.kt
class AlarmReceiver : BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        // Send notification to user
    }
}

// MainActivity.kt
fun setAlarms(context: Context) {
    val alarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
    val times = arrayOf("07:00", "12:00", "15:00", "18:00", "21:00")
    
    for (time in times) {
        val components = time.split(":")
        val hour = components[0].toInt()
        val minute = components[1].toInt()
        
        val calendar = Calendar.getInstance()
        calendar.set(Calendar.HOUR_OF_DAY, hour)
        calendar.set(Calendar.MINUTE, minute)
        
        val intent = Intent(context, AlarmReceiver::class.java)
        val pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0)
        
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.timeInMillis, AlarmManager.INTERVAL_DAY, pendingIntent)
    }
}

Remember to register AlarmReceiver in AndroidManifest.xml and implement notification logic in onReceive.
