How to add calendar events to default calendar, silently without Intent, in android 4?

Question

I want to add calendar events programmatically (directly) in android 4+. Is it this possible to be tested on emulator? I don\'t own an android phone. Some sample code wou

Answer 1

Using this code, you can programmatically add an event to device calendar. I have tested in Marshmallow, and it works fine for me.

private void addToDeviceCalendar(String startDate,String endDate, String title,String description, String location) {

        String stDate = startDate;
        String enDate = endDate;

        GregorianCalendar calDate = new GregorianCalendar();
        //GregorianCalendar calEndDate = new GregorianCalendar();

        SimpleDateFormat originalFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");
        SimpleDateFormat targetFormat = new SimpleDateFormat("yyyy,MM,dd,HH,mm");
        Date date,edate;
        try {
            date = originalFormat.parse(startDate);
            stDate=targetFormat.format(date);

        } catch (ParseException ex) {}

        long startMillis = 0;
        long endMillis = 0;
        String dates[] = stDate.split(",");

        SD_YeaR = dates[0];
        SD_MontH = dates[1];
        SD_DaY = dates[2];
        SD_HouR = dates[3];
        SD_MinutE = dates[4];


        /*Log.e("YeaR ", SD_YeaR);
        Log.e("MontH ",SD_MontH );
        Log.e("DaY ", SD_DaY);
        Log.e(" HouR", SD_HouR);
        Log.e("MinutE ", SD_MinutE);*/

        calDate.set(Integer.parseInt(SD_YeaR), Integer.parseInt(SD_MontH)-1, Integer.parseInt(SD_DaY), Integer.parseInt(SD_HouR), Integer.parseInt(SD_MinutE));
        startMillis = calDate.getTimeInMillis();
/*
        try {
            edate = originalFormat.parse(endDate);
            enDate=targetFormat.format(edate);

        } catch (ParseException ex) {}


        String end_dates[] = endDate.split(",");

        String ED_YeaR = end_dates[0];
        String ED_MontH = end_dates[1];
        String ED_DaY = end_dates[2];

        String ED_HouR = end_dates[3];
        String ED_MinutE = end_dates[4];


        calEndDate.set(Integer.parseInt(ED_YeaR), Integer.parseInt(ED_MontH)-1, Integer.parseInt(ED_DaY), Integer.parseInt(ED_HouR), Integer.parseInt(ED_MinutE));
        endMillis = calEndDate.getTimeInMillis();*/

        try {
            ContentResolver cr = getActivity().getContentResolver();
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Events.DTSTART, startMillis);
            values.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis() + 60 * 60 * 1000);
            values.put(CalendarContract.Events.TITLE, title);
            values.put(CalendarContract.Events.DESCRIPTION, description);
            values.put(CalendarContract.Events.EVENT_LOCATION,location);
            values.put(CalendarContract.Events.HAS_ALARM,1);
            values.put(CalendarContract.Events.CALENDAR_ID, 1);
            values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance()
                    .getTimeZone().getID());
            System.out.println(Calendar.getInstance().getTimeZone().getID());
            if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {

                return;
            }
            Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

            long eventId = Long.parseLong(uri.getLastPathSegment());
            Log.d("Ketan_Event_Id", String.valueOf(eventId));

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
