Retrieving last added event data from android calendar

Question

I want to extract the data of the last added event from the Android calendar . I use this code to get the 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 just add the 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 that, I simply retrieve the data for 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_calendar = cr.query( Uri.parse("content://com.android.calendar/calendars"), new String[] { "_id", "displayname" }, null, null, null); } else { cursor_calendar = cr.query( Uri.parse("content://calendar/calendars"), new String[] { "_id", "displayname" }, null, null, null); } cursor_calendar.moveToFirst(); String[] CalNamess = new String[cursor_calendar.getCount()]; int[] CalIdss = new int[cursor_calendar.getCount()]; for (int i = 0; i < CalNamess.length; i++) { CalIdss[i] = cursor_calendar.getInt(0); CalNamess[i] = cursor_calendar.getString(1); cursor_calendar.moveToNext(); } cursor_calendar.close(); // ------------------------------------------------------------------------------- Cursor cursor_event; if (Integer.parseInt(Build.VERSION.SDK) >= 8) { cursor_event = cr.query( Uri.parse("content://com.android.calendar/events"), new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null); } else { cursor_event = cr.query(Uri.parse("content://calendar/events"), new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }, null, null, null); } boolean flag = false; String add = null; cursor_event.moveToFirst(); String[] CalNames = new String[cursor_event.getCount()]; int[] CalIds = new int[cursor_event.getCount()]; for (int i = 0; i < CalNames.length; i++) { CalIds[i] = cursor_event.getInt(0); if (ID == CalIds[i]) { flag = true; Toast.makeText(getApplicationContext(), "ID Found : " + CalIds[i], Toast.LENGTH_LONG).show(); CalNames[i] = "Event" + cursor_event.getInt(0) + ": \nTitle: " + cursor_event.getString(1) + "\nDescription: " + cursor_event.getString(2) + "\nStart Date: " + cursor_event.getLong(cursor_event .getColumnIndex("dtstart")) + cursor_event.getLong(cursor_event .getColumnIndex("dtend")) + 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.EndDate = new Date(cursor_event.getLong(4)); temp.StartDate = cursor_event.getLong(cursor_event .getColumnIndex("dtstart")); temp.EndDate = cursor_event.getLong(cursor_event .getColumnIndex("dtend")); temp.Location = cursor_event.getString(5); break; } cursor_event.moveToNext(); } return temp; } 

But I can not get the data of this event. I do not understand where the problem is. Please help me solve this problem.

use this code. his work in my aap

 public long GetMaxID(ContentResolver cr, Uri cal_uri, Context context) { Uri local_uri = cal_uri; if (cal_uri == null) { // local_uri = Uri.parse("content://calendar/calendars/" + // "events"); 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; } public static CalendarData GetEventDetails(String ID, Context context) { CalendarData temp = null; ContentResolver contentResolver = context.getContentResolver(); // Fetch a list of all calendars synced with the device, their display // names and whether the cursor = contentResolver.query( Uri.parse("content://com.android.calendar/calendars"), (new String[] { "_id", "displayName", "selected" }), null, null, null); HashSet<String> calendarIds = new HashSet<String>(); try { System.out.println("Count=" + cursor.getCount()); if (cursor.getCount() > 0) { System.out .println("the control is just inside of the cursor.count loop"); while (cursor.moveToNext()) { String _id = cursor.getString(0); String displayName = cursor.getString(1); Boolean selected = !cursor.getString(2).equals("0"); System.out.println("Id: " + _id + " Display Name: " + displayName + " Selected: " + selected); calendarIds.add(_id); } } } catch (AssertionError ex) { ex.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } // For each calendar, display all the events from the previous week to // the end of next week. // for (String id : calendarIds) for (int id = 0; id <= calendarIds.size(); id++) { Uri.Builder builder = Uri.parse( "content://com.android.calendar/instances/when") .buildUpon(); // Uri.Builder builder = // Uri.parse("content://com.android.calendar/calendars").buildUpon(); long now = new Date().getTime(); ContentUris .appendId(builder, now - DateUtils.DAY_IN_MILLIS * 10000); ContentUris .appendId(builder, now + DateUtils.DAY_IN_MILLIS * 10000); Cursor eventCursor = contentResolver.query(builder.build(), new String[] { "_id", "title", "begin", "end", "allDay" }, "Calendars._id=" + id, null, null); System.out.println(id + " eventCursor count=" + eventCursor.getCount()); if (eventCursor.getCount() > 0) { eventCursor.moveToFirst(); while (eventCursor.moveToNext()) { Object mbeg_date, beg_date, beg_time, end_date, end_time; final String eventID = eventCursor.getString(0); final String title = eventCursor.getString(1); final Date begin = new Date(eventCursor.getLong(2)); final Date end = new Date(eventCursor.getLong(3)); final Boolean allDay = !eventCursor.getString(4) .equals("0"); if (eventID.equals(ID)) { temp = new CalendarData(); temp.Title = eventCursor.getString(1); temp.StartDate = eventCursor.getLong(2); temp.EndDate = eventCursor.getLong(3); break; } } } // break; } return temp; }

I used the following code to retrieve all the data in a calendar, which:

 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 is all you need, as I assume it will make it a little easier to get data for the 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(); } 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(); } System.out.println("My log--------" + all);
