super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
}
fun addCalendarEvent(view: View) {
val calendarEvent: Calendar = Calendar.getInstance()
val intent = Intent(Intent.ACTION_EDIT)
intent.type = "vnd.android.cursor.item/event"
intent.putExtra("beginTime", calendarEvent.timeInMillis)
intent.putExtra("allDay", true)
import android.content.Intent
import android.os.Bundle
import android.view.View
import androidx.appcompat.app.AppCompatActivity
import java.util.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
title = "KotlinApp"
}
fun addCalendarEvent(view: View) {
val calendarEvent: Calendar = Calendar.getInstance()
val intent = Intent(Intent.ACTION_EDIT)
intent.type = "vnd.android.cursor.item/event"
intent.putExtra("beginTime", calendarEvent.timeInMillis)
intent.putExtra("allDay", true)
intent.putExtra("rule", "FREQ=YEARLY")
intent.putExtra("endTime", calendarEvent.timeInMillis + 60 * 60 * 1000)

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon
from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
