if add event in calender use below code , that work in my calender.

// this code for add event in calender.

    ContentResolver cr = getContentResolver();
    ContentValues values = new ContentValues();
    values.put(Events.ALL_DAY, Events.ALL_DAY_VALUE);
    values.put(Events.DTSTART, startTimeInMilli);
    values.put(Events.DTEND, endTimeInMilli);
    values.put(Events.TITLE, strTaskName);
    values.put(Events.DESCRIPTION, strDescription);
    values.put(Events.CALENDAR_ID, 0);
    values.put(Events.VISIBILITY, Events.VISIBILITY_VALUE);

    Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
    Uri uri = cr.insert(EVENTS_URI, values);
    long eventID = Long.parseLong(uri.getLastPathSegment());

// this function call upper code.

 private String getCalendarUriBase(Activity act) {

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

// other static class for event constants.

 public class Events {

public static String ALL_DAY = "allDay";
public static String DTSTART = "dtstart";
public static String DTEND = "dtend";
public static String TITLE = "title";
public static String DESCRIPTION = "description";
public static String CALENDAR_ID = "calendar_id";
public static String EVENT_TIMEZONE = "eventTimezone";

public static String VISIBILITY = "visibility";
public static String HASALARM = "hasAlarm";

public static int VISIBILITY_VALUE = 0;
public static int HASALARM_VALUE = 1;
public static int ALL_DAY_VALUE = 0;

}

You need to pass calendar id of your app in your intent putExtra.

calIntent.putExtra(Events.CALENDAR_ID , my_cal_id);

To get list of all available calendar in your device you can use following code:

if(android.os.Build.VERSION.SDK_INT 
                       >= android.os.Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)
    cursor = getContentResolver().query(Calendars.CONTENT_URI,new String[] 
          { Calendars._ID, Calendars.CALENDAR_DISPLAY_NAME }, null ,null, null);
else
    cursor = getContentResolver().query(Uri.parse("content://com.android.calendar
    /calendars"),new String[] { "_id", "displayName" }, "selected=1",null, null);

        if (cursor != null && cursor.moveToFirst()) {
            String[] calNames = new String[cursor.getCount()];
            int[] calIds = new int[cursor.getCount()];
            for (int i = 0; i < calNames.length; i++) {

                calIds[i] = cursor.getInt(0);
                calNames[i] = cursor.getString(1);
                System.out.println(""+cursor.getInt(0) + " -- "+ 
                                                           cursor.getString(1));
                cursor.moveToNext();
            }
            cursor.close();
