Question

I have problem with adding events to Android Calendar.
My minimum SDK version is 7. I use Intent to add event, but problems is with various API.
I use this:

             String eventUriString;
    if (Build.VERSION.SDK_INT > 7)
     eventUriString = "content://com.android.calendar/events";
    else  eventUriString = "content://calendar/events";

    ContentValues eventValues = new ContentValues();

    eventValues.put("calendar_id", 1); 
    eventValues.put("title", "title");
    eventValues.put("description", desc);
    eventValues.put("eventLocation", "");

    long endDate = startDate + 1000 * 60 * 60; 

    eventValues.put("dtstart", MyClass.getDate());
    eventValues.put("dtend", endDate);

    eventValues.put("eventStatus", 0); 
    eventValues.put("visibility", 2); 
    eventValues.put("transparency", 0); 

    eventValues.put("hasAlarm", 0); 

    Uri eventUri = context.getContentResolver().insert(Uri.parse(eventUriString), eventValues);
    long eventID = Long.parseLong(eventUri.getLastPathSegment());

to Edit some events I use:

String calendarUriBase = null;
            long id = MyEvents.getID(p);  //something ID from my another class
        Uri calendars = Uri.parse("content://calendar/calendars");
        Cursor managedCursor = null;
        try {
            managedCursor = managedQuery(calendars, null, null, null, null);
        } catch (Exception e) {
            // eat
        }

        if (managedCursor != null) {
            calendarUriBase = "content://calendar/";
        } else {
            calendars = Uri.parse("content://com.android.calendar/calendars");
            try {
                managedCursor = managedQuery(calendars, null, null, null, null);
            } catch (Exception e) {
                // eat
            }

            if (managedCursor != null) {
                calendarUriBase = "content://com.android.calendar/";
            }

        }

        ContentValues event = new ContentValues();

        event.put("title", "new Title");

        Uri eventsUri = Uri.parse(calendarUriBase+"events");
        Uri eventUri = ContentUris.withAppendedId(eventsUri, id);

        getContentResolver().update(eventUri, event, null, null);

and it work on my phone (SE X8 with Android 2.3.7) but doesn’t work on SDK 14.

Is anywhere universal code, which I can use to add events to Calendar Android works on every various SDK? I have no idea how it make. I must use API 7 because my manager want. Have you any ideas how do that?

In ICS a new Calendar API is introduced so your code will not work in ICS.
New Public APIs in ICS

In order to support adding events to all calendars you can change your code like this –

if (Build.VERSION.SDK_INT >= 14) {
                saveCalendarEventICS();
            }
            else {
                int cal_id = getCalendar_ID();
                if(cal_id != 0){
                    saveCalendarEvent(cal_id);
                }
            }

private int getCalendar_ID() {
            // TODO Auto-generated method stub
            int calendar_id         = 0;
            String[] projection     = new String[] { "_id", "name" };
            String selection        = "selected=1";
            String path             = "calendars";
            Cursor calendarCursor   = getCalendarCursor(projection, selection, path);

            if (calendarCursor != null && calendarCursor.moveToFirst()) {
                int nameColumn      = calendarCursor.getColumnIndex("name");
                int idColumn        = calendarCursor.getColumnIndex("_id");
                do {
                    String calName  = calendarCursor.getString(nameColumn);
                    String calId    = calendarCursor.getString(idColumn);
                    if (calName != null /*&& calName.contains("Test")*/) {
                        calendar_id = Integer.parseInt(calId);
                    }
                } while (calendarCursor.moveToNext());
            }
            return calendar_id;
        }

private void saveCalendarEventICS() {

            Intent intent = new Intent(Intent.ACTION_INSERT)
             .setType("vnd.android.cursor.item/event")
             .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, frsttime)
             .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, sncdtime)
             .putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY , false) // just included for completeness
             .putExtra(Events.TITLE, vl_hldr[0])
             .putExtra(Events.DESCRIPTION, vl_hldr[2])
             .putExtra(Events.EVENT_LOCATION, vl_hldr[1])
             .putExtra(Events.RRULE, "FREQ=DAILY;COUNT=10") 
             .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
             .putExtra(Events.ACCESS_LEVEL, Events.ACCESS_PRIVATE)
             .putExtra(Events.ALLOWED_REMINDERS, "METHOD_DEFAULT")
             .putExtra(Intent.EXTRA_EMAIL, "");
            startActivity(intent);
        }


private void saveCalendarEvent(int calid) {
            // TODO Auto-generated method stub

//Create the event here -----------


                Uri newEvent;
                if (Build.VERSION.SDK_INT >= 8) {
                    //newEvent = Uri.parse("content://com.android.calendar/events");
                    newEvent = ctx.getContentResolver().insert(Uri.parse("content://com.android.calendar/events"), event);

                    if (newEvent != null) {
                        long id = Long.parseLong( newEvent.getLastPathSegment() );
                        ContentValues values = new ContentValues();
                        values.put( "event_id", id );
                        values.put( "method", 1 );
                        values.put( "minutes", 15 ); // 15 minuti

                        getContentResolver().insert( Uri.parse( "content://com.android.calendar/reminders" ), values );

                    if (newEvent != null) {
                        long id = Long.parseLong( newEvent.getLastPathSegment() );
                        ContentValues values = new ContentValues();
                        values.put( "event_id", id );

                        values.put( "minutes", 15 ); // 15 minuti

                        getContentResolver().insert( Uri.parse( "content://calendar/reminders" ), values );
                    }
                }

            }catch(Exception ee){}
