From what I understand, if you have no calendars selected in the native app, then they will not be available to any applications.

The above code worked for me, but now I've simplified it. Try the following instead.

var calendars = [];
var selectedCalendarName;
var selectedCalendarId;
var pickerData = [];
 
var win = Ti.UI.createWindow({
  backgroundColor: 'white',
  exitOnClose: true,
  fullscreen: false,
  layout: 'vertical',
  title: 'Calendar Demo'
});
 
var scrollView = Ti.UI.createScrollView({
  backgroundColor: '#eee',
  height: 500,
  top: 20
});
 
var label = Ti.UI.createLabel({
  backgroundColor: 'white',
  text: 'Click on the button to display the events for the selected calendar',
  textAlign: Ti.UI.TEXT_ALIGNMENT_CENTER,
  top: 20
});
scrollView.add(label);
 
var selectableCalendars = Ti.Android.Calendar.selectableCalendars;
for (var i = 0, ilen = selectableCalendars.length; i < ilen; i++) {
  calendars.push({ name: selectableCalendars[i].name, id: selectableCalendars[i].id });
  pickerData.push( Ti.UI.createPickerRow({ title: calendars[i].name }) );
  if(i === 0){
    selectedCalendarName = selectableCalendars[i].name;
    selectedCalendarId = selectableCalendars[i].id;
  }
}
var selectableCalendars = null;
 
if(!calendars.length){
  label.text = 'No calendars available. Select at least one in the native calendar before using this app';
} else {
  label.text = 'Click button to view calendar events';
 
  var picker = Ti.UI.createPicker({
    top:20
  });
 
  picker.add(pickerData);
  win.add(picker);
 
  picker.addEventListener('change', function(e){
    for (var i = 0, ilen = calendars.length; i < ilen; i++) {
      if(calendars[i].name === e.row.title){
        selectedCalendarName = calendars[i].name;
        selectedCalendarId = calendars[i].id;
      }
    }
  });
 
  var button = Ti.UI.createButton({
    title: 'View events',
    top: 20
  });
  win.add(button);
 
  button.addEventListener('click', function(e){
    label.text = 'Generating...';
 
    var currentYear = new Date().getFullYear();
 
    var consoleString = '';
 
    function print(s) {
      if (consoleString.length) {
        consoleString = consoleString + '\n';
      }
      consoleString = consoleString + s;
    }
 
    var calendar = Ti.Android.Calendar.getCalendarById(selectedCalendarId);
 
    function printReminder(r) {
      var typetext = '[method unknown]';
      if (r.method == Ti.Android.Calendar.METHOD_EMAIL) {
        typetext = 'Email';
      } else if (r.method == Ti.Android.Calendar.METHOD_SMS) {
        typetext = 'SMS';
      } else if (r.method == Ti.Android.Calendar.METHOD_ALERT) {
        typetext = 'Alert';
      } else if (r.method == Ti.Android.Calendar.METHOD_DEFAULT) {
        typetext = '[default reminder method]';
      }
      print(typetext + ' reminder to be sent ' + r.minutes + ' minutes before the event');
    }
 
    function printAlert(a) {
      print('Alert id ' + a.id + ' begin ' + a.begin + '; end ' + a.end + '; alarmTime ' + a.alarmTime + '; minutes ' + a.minutes);
    }
 
    function printEvent(event) {
      if (event.allDay) {
        print('Event: ' + event.title + '; ' + event.begin.toLocaleDateString() + ' (all day)');
      } else {
        print('Event: ' + event.title + '; ' + event.begin.toLocaleDateString() + ' ' + event.begin.toLocaleTimeString()+ '-' + event.end.toLocaleTimeString());
      }
 
      var reminders = event.reminders;
      if (reminders && reminders.length) {
        print('There is/are ' + reminders.length + ' reminder(s)');
        for (var i = 0; i < reminders.length; i++) {
          printReminder(reminders[i]);
        }
      }
 
      print('hasAlarm? ' + event.hasAlarm);
      var alerts = event.alerts;
      if (alerts && alerts.length) {
        for (var i = 0; i < alerts.length; i++) {
          printAlert(alerts[i]);
        }
      }
 
      var status = event.status;
      if (status == Ti.Android.Calendar.STATUS_TENTATIVE) {
        print('This event is tentative');
      }
      if (status == Ti.Android.Calendar.STATUS_CONFIRMED) {
        print('This event is confirmed');
      }
      if (status == Ti.Android.Calendar.STATUS_CANCELED) {
        print('This event was canceled');
      }
    }
 
    var events = calendar.getEventsInYear(currentYear);
    if (events && events.length) {
      print(events.length + ' event(s) in ' + currentYear);
      print('');
      for (var i = 0; i < events.length; i++) {
        printEvent(events[i]);
        print('');
      }
    } else {
      print('No events');
    }
 
    label.text = consoleString;
  });
}
 
win.add(scrollView);
 
win.open();

The following has been tested and works (Titanium 1.8.2, Android 2.3.3) when there are existing calendars on the device.

It's only a demo, so you will probably want to restructure it for a production app.

var win = Ti.UI.createWindow({
  backgroundColor: 'white',
  exitOnClose: true,
  fullscreen: false,
  layout: 'vertical',
  title: 'Calendar Demo'
});
 
function getCalendars(selectableCalendars) {
  var calendars = [];
  var thisCalendar = {};
  var isCalendarSelected = false;
  for (var i = 0, ilen = selectableCalendars.length; i < ilen; i++) {
    thisCalendar = { name: selectableCalendars[i].name, id: selectableCalendars[i].id, selected: false };
    if( Ti.App.Properties.hasProperty('selectedCalendarName') && (Ti.App.Properties.getString('selectedCalendarName') === selectableCalendars[i].name) ){
      thisCalendar.selected = true;
      isCalendarSelected = true;
    }
    calendars.push(thisCalendar);
  }
 
  if(!isCalendarSelected){
    Ti.App.Properties.setString('selectedCalendarName', selectableCalendars[0].name);
    Ti.App.Properties.setInt('selectedCalendarId', selectableCalendars[0].id);
    calendars[0].selected = true;
  }
  return calendars;
}
 
var pickerData = [];
var calendars = getCalendars(Ti.Android.Calendar.selectableCalendars);
var selectedPickerIndex = -1;
 
for (var i = 0, ilen = calendars.length; i < ilen; i++) {
  pickerData.push(Ti.UI.createPickerRow({
    title: calendars[i].name
  }));
  if(calendars[i].selected){
    selectedPickerIndex = i;
  }
}
 
var picker = Ti.UI.createPicker({
  top:20
});
 
picker.add(pickerData);
win.add(picker);
 
picker.addEventListener('change', function(e){
  for (var i = 0, ilen = calendars.length; i < ilen; i++) {
    if(calendars[i].name === e.row.title){
      Ti.App.Properties.setString('selectedCalendarName', calendars[i].name);
      Ti.App.Properties.setInt('selectedCalendarId', calendars[i].id);
    }
  }
});
 
var button = Ti.UI.createButton({
  title: 'View events',
  top: 20
});
win.add(button);
 
var scrollView = Ti.UI.createScrollView({
  backgroundColor: '#eee',
  height: 500,
  top: 20
});
win.add(scrollView);
 
var label = Ti.UI.createLabel({
  backgroundColor: 'white',
  color: 'black',
  text: 'Click button to view calendar events'
});
scrollView.add(label);
 
button.addEventListener('click', function(e){
  label.text = 'Generating...';
 
  var selectedCalendarName = Ti.App.Properties.getString('selectedCalendarName');
  var selectedCalendarId = Ti.App.Properties.getInt('selectedCalendarId');
  var currentYear = new Date().getFullYear();
 
  var consoleString = '';
 
  function print(s) {
    Ti.API.info(s);
    if (consoleString.length > 0) {
      consoleString = consoleString + '\n';
    }
    consoleString = consoleString + s;
  }
 
  var calendar = Ti.Android.Calendar.getCalendarById(selectedCalendarId);
 
  function printReminder(r) {
    var typetext = '[method unknown]';
    if (r.method == Ti.Android.Calendar.METHOD_EMAIL) {

  function printEvent(event) {
    if (event.allDay) {

    } else {
