Use this API in your code.. It will help u to insert event, event with reminder and event with meeting can be enabled... This api works for platform 2.1 and above Those who uses less then 2.1 instead of content://com.android.calendar/events use content://calendar/events

public static long pushAppointmentsToCalender(Activity curActivity, String title, String addInfo, String place, int status, long startDate, boolean needReminder, boolean needMailService) {
/***************** Event: note(without alert) *******************/

String eventUriString = "content://com.android.calendar/events";
ContentValues eventValues = new ContentValues();

eventValues.put("calendar_id", 1); // id, We need to choose from
                                    // our mobile for primary
                                    // its 1
eventValues.put("title", title);
eventValues.put("description", addInfo);
eventValues.put("eventLocation", place);

long endDate = startDate + 1000 * 60 * 60; // For next 1hr

eventValues.put("dtstart", startDate);
eventValues.put("dtend", endDate);

// values.put("allDay", 1); //If it is bithday alarm or such
// kind (which should remind me for whole day) 0 for false, 1
// for true
eventValues.put("eventStatus", status); // This information is
// sufficient for most
// entries tentative (0),
// confirmed (1) or canceled
// (2):
eventValues.put("eventTimezone", "UTC/GMT +2:00");

/*Comment below visibility and transparency column to avoid java.lang.IllegalArgumentException column visibility is invalid error */

/*eventValues.put("visibility", 3); // visibility to default (0),
                                    // confidential (1), private
                                    // (2), or public (3):
eventValues.put("transparency", 0); // You can control whether
                                    // an event consumes time
                                    // opaque (0) or transparent
                                    // (1).
  */
eventValues.put("hasAlarm", 1); // 0 for false, 1 for true

Uri eventUri = curActivity.getApplicationContext().getContentResolver().insert(Uri.parse(eventUriString), eventValues);
long eventID = Long.parseLong(eventUri.getLastPathSegment());

if (needReminder) {
    /***************** Event: Reminder(with alert) Adding reminder to event *******************/

    String reminderUriString = "content://com.android.calendar/reminders";

    ContentValues reminderValues = new ContentValues();

    reminderValues.put("event_id", eventID);
    reminderValues.put("minutes", 5); // Default value of the
                                        // system. Minutes is a
                                        // integer
    reminderValues.put("method", 1); // Alert Methods: Default(0),
                                        // Alert(1), Email(2),
                                        // SMS(3)

    Uri reminderUri = curActivity.getApplicationContext().getContentResolver().insert(Uri.parse(reminderUriString), reminderValues);
}
