Answer 1

Here is a class I used for ICS

import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentUris;
import android.content.ContentValues;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.CalendarContract;
import android.provider.CalendarContract.Calendars;
import android.provider.CalendarContract.Events;
import android.provider.CalendarContract.Reminders;
import android.util.Log;

public class IcsCalendarHelper {

//Remember to initialize this activityObj first, by calling initActivityObj(this) from 
//your activity  
private static final String DEBUG_TAG = "CalendarActivity";
private static Activity activityObj;

public static void initActivityObj(Activity obj)
{
        activityObj = obj;
}

public static void IcsMakeNewCalendarEntry(String title,String description,String location,long startTime,long endTime, int allDay,int hasAlarm, int calendarId,int selectedReminderValue) {

        ContentResolver cr = activityObj.getContentResolver();
        ContentValues values = new ContentValues();
        values.put(Events.DTSTART, startTime);
        values.put(Events.DTEND, endTime);
        values.put(Events.TITLE, title);
        values.put(Events.DESCRIPTION, description);
        values.put(Events.CALENDAR_ID, calendarId);

        if (allDay == 1)
        {
            values.put(Events.ALL_DAY, true);
        }

        if (hasAlarm==1)
        {
            values.put(Events.HAS_ALARM, true);
        }

        //Get current timezone
        values.put(Events.EVENT_TIMEZONE,TimeZone.getDefault().getID());
        Log.i(DEBUG_TAG, "Timezone retrieved=>"+TimeZone.getDefault().getID());
        Uri uri = cr.insert(Events.CONTENT_URI, values);
        Log.i(DEBUG_TAG, "Uri returned=>"+uri.toString());
        // get the event ID that is the last element in the Uri
        long eventID = Long.parseLong(uri.getLastPathSegment());

        if (hasAlarm==1)
        {
            ContentValues reminders = new ContentValues();
            reminders.put(Reminders.EVENT_ID, eventID);
            reminders.put(Reminders.METHOD, Reminders.METHOD_ALERT);
            reminders.put(Reminders.MINUTES, selectedReminderValue);

            Uri uri2 = cr.insert(Reminders.CONTENT_URI, reminders);
        }


}

}

If your app is targeting Android 6.0 and above, the class below contains helper functions to request for READ/WRITE calendar permissions during runtime.

Hi use the following code to add the event programmatically to the calendar.

        Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
        ContentResolver cr = getContentResolver();
        ContentValues values = new ContentValues();
        values.put("calendar_id", id);
        values.put("title", tasktitle);
        values.put("allDay", 0);
        values.put("dtstart", settime); 
        values.put("dtend", cal.getTimeInMillis()+60*60*1000); 
        values.put("description", description);
        values.put("visibility", 0);
        values.put("transparency", 0);
        values.put("hasAttendeeData", 1);
        values.put("hasAlarm", 0);
        event = cr.insert(EVENT_URI, values);
        event1=event; 
        dat1 = event.toString();
        long id=-1;
        if (event != null)
        {
             id = Long.parseLong(event.getLastPathSegment());
             ContentValues values1 = new ContentValues();
             values1.put("event_id", id);
             values1.put("method", 1); //METHOD_ALERT

            Uri reminder = Uri.parse(getCalendarUriBase(this) + "reminders");
            this.getContentResolver().insert(reminder, values1);


                 ContentValues attendees = new ContentValues();
                 attendees.put("event_id", id);
                 attendees.put("attendeeEmail", partmail1);
                 attendees.put("attendeeRelationship", 2);//RELATIONSHIP_ATTENDEE
                 attendees.put("attendeeStatus", 3); //ATTENDEE_STATUS_INVITED       
                 attendees.put("attendeeType", 1); //TYPE_REQUIRED

                id1=(int)id;
                alarmid = (int) id;
                Uri attendeesUri = null;
                if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
                {
                         attendeesUri = Uri.parse("content://com.android.calendar/attendees");
                }
                else if(Integer.parseInt(Build.VERSION.SDK) < 8)
                {
                        attendeesUri = Uri.parse("content://calendar/attendees");
                }
                this.getContentResolver().insert(attendeesUri, attendees);

                Toast.makeText(this, "Task Scheduled Successfully", Toast.LENGTH_SHORT).show();
            }



        // reminder insert
        Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
        values = new ContentValues();
        values.put( "event_id", id);
        values.put( "method", 1 );
        values.put( "minutes", 0 );
        cr.insert( REMINDERS_URI, values );
