Android Calendar, remove events and create recurrent events.

i am happy because i am getting many progress with my app (thanks to you).. Now i am stopped in this point:

1 - Need remove some events, or marked like "done" or something. When i create the event, i set an id to the event.

var calendar = Ti.Calendar.getCalendarById(CALENDAR_TO_USE);
var details = {
      id: nombreEvento,  // custom event id
      title: textTitulo.getValue() ,
      description: textNotas.getValue(),
      begin: fechaHoraIni,
      end: fechaHoraFin
};
var evento = calendar.createEvent(details);

2 - Is there a way to create a RecurrenceRule ? (Android) .. if so.. can you explain me how ?, documentation is only for iOS, but does anybody solve it in android ?

As always, thanks in advance for your help..
