ICalendar ical = Biweekly.parse(str).first();
VEvent event = ical.getEvents().get(0);
String summary = event.getSummary().getValue();ICalendar ical = new ICalendar();
VEvent event = new VEvent();
Summary summary = event.setSummary("Team Meeting");
summary.setLanguage("en-us");
Date start = ...
event.setDateStart(start);
Duration duration = new Duration.Builder().hours(1).build();
event.setDuration(duration);
Recurrence recur = new Recurrence.Builder(Frequency.WEEKLY).interval(2).build();

ical.addEvent(event);
String str = Biweekly.write(ical).go();- Simple, intuitive API (see Examples).
- Android compatibility.
- Full compliance with iCalendar and vCalendar specifications (see Supported Specifications).
- Supports XML and JSON formats (see Supported Specifications).
- Full timezone support (uses tzurl.org for timezone definitions).
- Extensive unit test coverage.
- Low Java version requirement (1.6 or above).
- Few dependencies on external libraries. Dependencies can be selectively excluded based on the functionality that is needed (see Dependencies).
