Adding event with reminders to calendar with 'Intent.putExtra()' way of doing

I'm trying to add events to calendar with the following code :

public Intent calPopulation()
Intent calIntent = new Intent(Intent.ACTION_INSERT);
calIntent.putExtra(CalendarContract.Events.TITLE, this._title);

GregorianCalendar calDate = new GregorianCalendar(this._year,this._month, this._day, this._hour, this._minute);
calIntent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, calDate.getTimeInMillis());
calIntent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, calDate.getTimeInMillis()+60*60*1000);
calIntent.putExtra(CalendarContract.Events.HAS_ALARM, true);
calIntent.putExtra(CalendarContract.Reminders.EVENT_ID, CalendarContract.Events._ID);
calIntent.putExtra(CalendarContract.Events.ALLOWED_REMINDERS, "METHOD_DEFAULT");
calIntent.putExtra(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);

return calIntent;

And then launch the action with :

I don't have any issue, the calendar app event launched with the correct information I entered into my app, except that it does not fill in the event the reminder I would like to add.

Do you have any clues? I tried to search within many threads using this method (I mean the intent.putExtra) but never find anything interesting.

Other point, is there a way to directly save the event + reminder into the calendar without opening calendar App and requesting for user action?

Thanks in advance.

No answer according to the method I pointed out, but another way I found to add event with reminders to the calendar.

Hereunder methods are working fine for me :

// Add an event to the calendar of the user.
    public void addEvent(Context context) {
        GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);

        try {
            ContentResolver cr = context.getContentResolver();
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
            values.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);
            values.put(CalendarContract.Events.TITLE, this._title);
            values.put(CalendarContract.Events.CALENDAR_ID, 1);
            values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance()
            Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

            // Save the eventId into the Task object for possible future delete.
            this._eventId = Long.parseLong(uri.getLastPathSegment());
            // Add a 5 minute, 1 hour and 1 day reminders (3 reminders)
            setReminder(cr, this._eventId, 5);
            setReminder(cr, this._eventId, 60);
            setReminder(cr, this._eventId, 1440);

        } catch (Exception e) {

    // routine to add reminders with the event
    public void setReminder(ContentResolver cr, long eventID, int timeBefore) {
        try {
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Reminders.MINUTES, timeBefore);
            values.put(CalendarContract.Reminders.EVENT_ID, eventID);
            values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
            Uri uri = cr.insert(CalendarContract.Reminders.CONTENT_URI, values);
            Cursor c = CalendarContract.Reminders.query(cr, eventID,
                    new String[]{CalendarContract.Reminders.MINUTES});
            if (c.moveToFirst()) {
                        + c.getInt(c.getColumnIndex(CalendarContract.Reminders.MINUTES)));
        } catch (Exception e) {

    // function to remove an event from the calendar using the eventId stored within the Task object.
    public void removeEvent(Context context) {
        ContentResolver cr = context.getContentResolver();

        int iNumRowsDeleted = 0;

        Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
        Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);
        iNumRowsDeleted = cr.delete(eventUri, null, null);

        Log.i(DEBUG_TAG, "Deleted " + iNumRowsDeleted + " calendar entry.");

    public int updateEvent(Context context) {
        int iNumRowsUpdated = 0;
        GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);

        ContentValues event = new ContentValues();

        event.put(CalendarContract.Events.TITLE, this._title);
        event.put("hasAlarm", 1); // 0 for false, 1 for true
        event.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
        event.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);

        Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
        Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);

        iNumRowsUpdated = context.getContentResolver().update(eventUri, event, null,

        // TODO put text into strings.xml
        Log.i(DEBUG_TAG, "Updated " + iNumRowsUpdated + " calendar entry.");

        return iNumRowsUpdated;

Hope this could help others that encountered the same problem I had :).
