Cannot Read Calendar Event with Recurrence Rule

I created an event with repeat rule "FREQ=MONTHLY;BYMONTHDAY=16;COUNT=10". I saw the event on my two Android Calendars apps, and also on Google Calendar web site. I can read all other events from my app, but I do not see this event. Only difference is that this event has repeat rule. Here is my code for reading.
public static MyEvents readCalendarMyEvent(Context context,Date date1, Date date2, int calendarID)
{
try
{
Calendar calendar1 = Calendar.getInstance();
calendar1.setTime(date1);
Calendar calendar2 = Calendar.getInstance();
calendar2.setTime(date2);
Uri l_eventUri;
if (Build.VERSION.SDK_INT >= 8) {
l_eventUri = Uri.parse("content://com.android.calendar/events");
} else {
l_eventUri = Uri.parse("content://calendar/events");
}
ContentResolver contentResolver = context.getContentResolver();
String dtstart = "dtstart";
String dtend = "dtend";
String[] l_projection = new String[] { CalendarContract.Events.CALENDAR_ID,
CalendarContract.Events.TITLE, //1
CalendarContract.Events.DESCRIPTION,
CalendarContract.Events.DTSTART,
CalendarContract.Events.DTEND,
CalendarContract.Events.EVENT_LOCATION,
CalendarContract.Events.EVENT_TIMEZONE,//6
CalendarContract.Events.HAS_ALARM,
CalendarContract.Events.RRULE,
CalendarContract.Events.RDATE,
CalendarContract.Events.ORGANIZER,
CalendarContract.Events.SELF_ATTENDEE_STATUS,//11

CalendarContract.Events.ALL_DAY,
CalendarContract.Events.DELETED,

CalendarContract.Events.GUESTS_CAN_SEE_GUESTS,
CalendarContract.Events.ALL_DAY,
CalendarContract.Events.ACCESS_LEVEL,
CalendarContract.Events.AVAILABILITY,
CalendarContract.Events.EXRULE,
CalendarContract.Events.EXDATE
};
String where = "(" + dtstart + ">"
+ calendar1.getTimeInMillis() + " and "
+ dtend + "<" + calendar2.getTimeInMillis() + " and "+
CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";
Cursor cursor= contentResolver.query(l_eventUri, l_projection, where, null,
"dtstart ASC");
cursor.moveToFirst();
// fetching calendars id
String str="";
MyEvents myEvents = new MyEvents();
for (int i = 0; i < cursor.getCount(); i++) {
int delete = cursor.getInt(15);
if( delete == 1)
{
cursor.moveToNext();
continue;
}
MyEvent myEvent = new MyEvent();
myEvent.ID = cursor.getInt(0);
myEvent.TITLE = cursor.getString(1);
myEvent.Note = cursor.getString(2);
str = cursor.getString(3);
if(str != null || str.length() <1)
{
myEvent.START_DATE = MillisecondsToDateTime(Long.parseLong(str));
myEvent.StartDate = getDate(Long.parseLong(str));
}
else
{
cursor.moveToNext();
continue;
}
str = cursor.getString(4);
if(str != null || str.length() <1)
myEvent.END_DATE = MillisecondsToDateTime(Long.parseLong(str));
myEvent.EVENT_LOCATION =cursor.getString(5);
myEvent.EVENT_TIMEZONE =cursor.getString(6);
myEvent.HAS_ALARM = cursor.getInt(7);
myEvent.RRULE = cursor.getString(8);
myEvent.RDATE = cursor.getString(9);
myEvent.ORGANIZER =cursor.getString(10);
myEvent.SELF_ATTENDEE_STATUS = cursor.getInt(11);
myEvent.GUESTS_CAN_MODIFY = cursor.getInt(12);
myEvent.EVENT_ID = cursor.getInt(13);
myEvent.ALL_DAY = cursor.getInt(14);
myEvent.GUESTS_CAN_INVITE_OTHERS= cursor.getInt(16);
myEvent.GUESTS_CAN_SEE_GUESTS= cursor.getInt(17);
myEvent.ALL_DAY= cursor.getInt(18);
myEvent.ACCESS_LEVEL= cursor.getInt(19);
myEvent.AVAILABILITY= cursor.getInt(20);
myEvent.EXRULE = cursor.getString(21);
myEvent.EXDATE = cursor.getString(22);
myEvents.Add(myEvent);
cursor.moveToNext();
}
return myEvents;
}
catch(Exception ex)
{
ex.printStackTrace();
}
return new MyEvents();
}

The problem was resolved. I made a mistake in the where clause. The following is correct on
String where = "(" + dtstart + ">"
+ calendar1.getTimeInMillis() + " and "
+ dtstart + "<" + calendar2.getTimeInMillis() + " and "+
CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";

Getting attendees details from Calendar Content Provider

I am trying to create a app which will fetch details of Events and Attendeesfrom Calendar app.
I am facing the problems which are"
1). In many of the events Title and their attendees does not match.
2). In many of the events I am getting 0 attendees

Retrieving Data of last added event from android calendar

I want to retrive the data of last added event from android calendar. I am using this code to get last id.
public static long getNewEventId(ContentResolver cr, Uri cal_uri)
{
Uri local_uri = cal_uri;
if (cal_uri == null)
{
local_uri = Uri.parse("content://com.android.calendar/events");
}
Cursor cursor = cr.query(local_uri,
new String[] { "MAX(_id) as max_id" }, null, null, "_id");
cursor.moveToFirst();
long max_val = cursor.getLong(cursor.getColumnIndex("max_id"));
return max_val + 1;
}
And then I simply add an event using this code:
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", SelectedDate);
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FsREQ=DAILY");
intent.putExtra("endTime", SelectedDate + 60 * 60 * 1000);
intent.putExtra("title", "Advance Scheduler Event");
startActivity(intent);
After this I simply retrieve the data of this event using this code:
public CalendarData EventDetails(int ID)
{
CalendarData temp = null;
// -------------------------------------------------------------------------------
ContentResolver cr = getContentResolver();
Cursor cursor_calendar;
if (Integer.parseInt(Build.VERSION.SDK) >= 8)

+ cursor_event.getString(5);
temp = new CalendarData();
temp.Title = cursor_event.getString(1);
temp.Description = cursor_event.getString(2);
// temp.StartDate = new Date(cursor_event.getLong(3));

temp.Location = cursor_event.getString(5);
break;
}
cursor_event.moveToNext();
}

}
But I can't get the data of this event. I am not getting where is the problem. Please, help me to solve this.

use this code. its working in my aap

I used the following code to retrieve all the data on the Calendar which is:
cr = getApplicationContext().getContentResolver();
caluri=CalendarContract.Events.CONTENT_URI;
atteuri=CalendarContract.Attendees.CONTENT_URI;
try
{
cur1 = cr.query(caluri, new String[]{Events.CALENDAR_ID,Events._ID, Events.TITLE, Events.DESCRIPTION,Events.DTSTART, Events.DTEND, Events.EVENT_LOCATION }, null, null, null);
if(cur1!=null){
while(cur1.moveToNext()){
cal_ID=cur1.getString(cur1.getColumnIndex(Events.CALENDAR_ID));
event_ID=cur1.getString(cur1.getColumnIndex(Events._ID));
cur2=cr.query(atteuri,new String[]{Attendees.ATTENDEE_NAME,Attendees.ATTENDEE_EMAIL}, Attendees.EVENT_ID +"=" +event_ID, null, null);
if(cur2!=null){
while(cur2.moveToNext()){
event_Title=cur1.getString(cur1.getColumnIndex(Events.TITLE));
event_Desc=cur1.getString(cur1.getColumnIndexOrThrow(Events.DESCRIPTION));
event_Start=new Date(cur1.getLong(cur1.getColumnIndex(Events.DTSTART)));
event_end=new Date(cur1.getLong(cur1.getColumnIndex(Events.DTEND)));
event_loc=cur1.getString(cur1.getColumnIndex(Events.EVENT_LOCATION));
attendee_name=cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_NAME));
attendee_Email=cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_EMAIL));
all_attendee +="\n"+attendee_name;
all_Emails +="\n"+attendee_Email;
}
cur2.close();
}
all +="Event title: " + event_Title + "\n" + "Event Description: " + event_Desc + "\n" +"Event Start: " + event_Start + "\n" + "Events End: " + event_end + "\n" + "Event Location: " + event_loc + "\n" + "Attendees: " + "\n" + all_attendee + "\n" + "Emails: "+ "\n" + all_Emails + "\n";
}
cur1.close();
}
}
catch(Exception e)
{
e.printStackTrace();
}
SO all what you need as I guess is to adjust it little bit get data for last event.

ContentResolver cr = getContentResolver();
Uri caluri = CalendarContract.Events.CONTENT_URI;
Uri atteuri = CalendarContract.Attendees.CONTENT_URI;
Cursor cur1, cur2;
String all = null;
try
{
cur1 = cr.query(caluri
, new String[]{ Events.CALENDAR_ID, Events._ID, Events.TITLE, Events.DESCRIPTION, Events.DTSTART, Events.DTEND, Events.EVENT_LOCATION }
, null, null, null);
if (cur1 != null)
{
while (cur1.moveToNext())
{
String event_Title = cur1.getString(cur1.getColumnIndex(Events.TITLE));
String event_Desc = cur1.getString(cur1.getColumnIndexOrThrow(Events.DESCRIPTION));
Date event_Start = new Date(cur1.getLong(cur1.getColumnIndex(Events.DTSTART)));
Date event_end = new Date(cur1.getLong(cur1.getColumnIndex(Events.DTEND)));
String event_loc = cur1.getString(cur1.getColumnIndex(Events.EVENT_LOCATION));
String all_attendee = null;
String all_Emails = null;
String cal_ID = cur1.getString(cur1.getColumnIndex(Events.CALENDAR_ID));
String event_ID = cur1.getString(cur1.getColumnIndex(Events._ID));
cur2 = cr.query(atteuri, new String[]{ Attendees.ATTENDEE_NAME, Attendees.ATTENDEE_EMAIL }
, Attendees.EVENT_ID + "=" + event_ID, null, null);
if (cur2 != null)
{
while (cur2.moveToNext())
{
String attendee_name = cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_NAME));
String attendee_Email = cur2.getString(cur2.getColumnIndex(Attendees.ATTENDEE_EMAIL));
all_attendee += "\n" + attendee_name;
all_Emails += "\n" + attendee_Email;
}
cur2.close();
}

how to get calendar event update on android device
