Can I add event to calendar without letting user know in android?

Issue

I want to add event to my native calendar using the below code. and it is working fine.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd HH:mm");
                final Calendar cal = Calendar.getInstance();
                try {
                    cal.setTime(formatter.parse(datetime));
                    eventdate = cal.get(Calendar.YEAR)+"/"+cal.get(Calendar.MONTH)+"/"+cal.get(Calendar.DAY_OF_MONTH)+" "+cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE);
                    Log.e("event date",eventdate);
                } 
                catch (ParseException e) {
                    e.printStackTrace();
                }
                Intent intent = new Intent(Intent.ACTION_EDIT);
                intent.setType("vnd.android.cursor.item/event");
                intent.putExtra("beginTime", cal.getTimeInMillis());
                intent.putExtra("allDay", true);
                intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
                intent.putExtra("title", title);
                intent.putExtra("description",desc);
                c.startActivity(intent);

This opens up a screen where it asks me to save event. and when I click on save, it saves my event to calendar.

Now, what I want is to add event directly to the native calendar, without showing the above screen. Is there any way to do that?

Solution

You can refer below code to add events in calender.

String GLOBAL_DATE_FORMAT = "yyyy-MM-dd HH:mm:ss";
String gameDate="2015-07-12 01:10:00";
        Date startDate = DateConstants.getDateFromString(
                gameDate,GLOBAL_DATE_FORMAT);
        long endDate = startDate.getTime()
                + (PTGConstantMethod.validateInteger(game
                        .getGame_duration()) * 1000);

        ContentValues event = new ContentValues();
        event.put("calendar_id", 1);
        event.put("title", "Game#" + game.getId());
        event.put("description", game.getLocation());
        event.put("eventLocation", game.getLocation());
        event.put("eventTimezone", TimeZone.getDefault().getID());
        event.put("dtstart", startDate.getTime());
        event.put("dtend", endDate);

        event.put("allDay", 0); // 0 for false, 1 for true
        event.put("eventStatus", 1);
        event.put("hasAlarm", 1); // 0 for false, 1 for true

        String eventUriString = "content://com.android.calendar/events";
        Uri eventUri = context.getApplicationContext()
                .getContentResolver()
                .insert(Uri.parse(eventUriString), event);
        long eventID = Long.parseLong(eventUri.getLastPathSegment());

// if reminder need to set


            int minutes=120;


            // add reminder for the event
            ContentValues reminders = new ContentValues();
            reminders.put("event_id", eventID);
            reminders.put("method", "1");
            reminders.put("minutes", minutes);

            String reminderUriString = "content://com.android.calendar/reminders";
            context.getApplicationContext().getContentResolver()
            .insert(Uri.parse(reminderUriString), reminders);
