Meet in Google Calendar API

问题

How can I add google meet in google calendar api in java? Please help me. I haven't understood the google documentation. https://developers.google.com/calendar/create-events. The source code is given here. Here, I want to create event using users gmail account. I have not any G-suite account

Event event = new Event()
    .setSummary(title)
    .setLocation(location)
    .setDescription(description);

DateTime startDateTime = new DateTime( date +"T"+startTime+"+06:00" );//"2020-05-05T11:00:00+06:00");
EventDateTime start = new EventDateTime()
    .setDateTime(startDateTime)
    .setTimeZone("Asia/Dhaka");
event.setStart(start);

DateTime endDateTime = new DateTime(date +"T"+endTime+"+06:00");//"2020-05-05T12:00:00+06:00");
EventDateTime end = new EventDateTime()
    .setDateTime(endDateTime)
    .setTimeZone("Asia/Dhaka");
event.setEnd(end);

String[] recurrence = new String[] {"RRULE:FREQ=DAILY;COUNT=1"};
event.setRecurrence(Arrays.asList(recurrence));

EventAttendee attendees[];

attendees = new EventAttendee[allAttendees.size()];

for(int i=0; i<allAttendees.size(); i++){
    // System.out.println(allAttendees.get(i));
    attendees[i] = new EventAttendee().setEmail(allAttendees.get(i));
}
event.setAttendees(Arrays.asList(attendees));

EventReminder[] reminderOverrides = new EventReminder[] {
    new EventReminder().setMethod("email").setMinutes(24 * 60),
    new EventReminder().setMethod("popup").setMinutes(10),
};


Event.Reminders reminders = new Event.Reminders()
    .setUseDefault(false)
    .setOverrides(Arrays.asList(reminderOverrides));
event.setReminders(reminders);

String calendarId = "primary";

try {
    abc = service.events().insert(calendarId, event);
} catch (IOException e) {
    e.printStackTrace();
}

try {
    event = service.events().insert(calendarId, event).execute();
} catch (IOException e) {
    e.printStackTrace();
}

String meetingId = event.getHangoutLink();
System.out.println("What is meeting ID? = "+meetingId);

Answer

You will need to use the JAVA API Documentation for Google Calendar

You have to create a new Meet request and then append it to the current event and before that, enable the conferenceDataVersion by setting it to 1. Before using the following code make sure that you have this setup.

Code

Event event = new Event()
                        .setSummary(title)
                        .setLocation(location)
                        .setDescription(description);

// Your previous code

/* The code needed - START */

ConferenceSolutionKey conferenceSKey = new ConferenceSolutionKey();
conferenceSKey.setType("eventHangout"); // Non-G suite user
CreateConferenceRequest createConferenceReq = new CreateConferenceRequest();
createConferenceReq.setRequestId("3whatisup3"); // ID generated by you
createConferenceReq.setConferenceSolutionKey(conferenceSKey);
ConferenceData conferenceData = new ConferenceData();
conferenceData.setCreateRequest(createConferenceReq);
event.setConferenceData(conferenceData); // attach the meeting to your event

/* The code needed - END */

String calendarId = "primary";

// There’s no need to declare the try-catch block twice

try {
    /* Code changes - START */

    // .setConferenceDataVersion(1) enables the creation of new meetings
    event = service.events().insert(calendarId, event).setConferenceDataVersion(1).execute();

    /* Code changes - END */

} catch (IOException e) {
    e.printStackTrace();
}

String meetingId = event.getHangoutLink();
System.out.println("What is meeting ID? = "+meetingId);

The final workable code for me is given below.

 Event event = new Event()
            .setSummary(title)
            .setLocation(location)
            .setDescription(description);


    DateTime startDateTime = new DateTime( date +"T"+startTime+"+06:00" );//"2020-05-05T11:00:00+06:00");
    EventDateTime start = new EventDateTime()
            .setDateTime(startDateTime)
            .setTimeZone("Asia/Dhaka");
    event.setStart(start);

    DateTime endDateTime = new DateTime(date +"T"+endTime+"+06:00");//"2020-05-05T12:00:00+06:00");
    EventDateTime end = new EventDateTime()
            .setDateTime(endDateTime)
            .setTimeZone("Asia/Dhaka");
    event.setEnd(end);

    String[] recurrence = new String[] {"RRULE:FREQ=DAILY;COUNT=1"};
    event.setRecurrence(Arrays.asList(recurrence));

  /*  s1 = "abc@gmail.com";
    s2 = "xyz@gmail.com";

    EventAttendee[] attendees = new EventAttendee[] {
            new EventAttendee().setEmail(s1),
            new EventAttendee().setEmail(s2),
    };*/



    EventAttendee attendees[];

    attendees = new EventAttendee[allAttendees.size()];

    for(int i=0; i<allAttendees.size(); i++){
       // System.out.println(allAttendees.get(i));
        attendees[i] = new EventAttendee().setEmail(allAttendees.get(i));
    }
    event.setAttendees(Arrays.asList(attendees));



    EventReminder[] reminderOverrides = new EventReminder[] {
            new EventReminder().setMethod("email").setMinutes(24 * 60),
            new EventReminder().setMethod("popup").setMinutes(10),
    };


    Event.Reminders reminders = new Event.Reminders()
            .setUseDefault(false)
            .setOverrides(Arrays.asList(reminderOverrides));
    event.setReminders(reminders);


    ConferenceSolutionKey conferenceSKey = new ConferenceSolutionKey();
    conferenceSKey.setType("hangoutsMeet"); // Non-G suite user
    CreateConferenceRequest createConferenceReq = new CreateConferenceRequest();
    createConferenceReq.setRequestId("3whatisup3"); // ID generated by you
    createConferenceReq.setConferenceSolutionKey(conferenceSKey);
    ConferenceData conferenceData = new ConferenceData();
    conferenceData.setCreateRequest(createConferenceReq);
    event.setConferenceData(conferenceData);

    String calendarId = "primary";

    try {
        event = service.events().insert(calendarId, event).setConferenceDataVersion(1).execute();
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.printf("Event created: %s\n", event.getHtmlLink());
    System.out.printf("Hangout Link %s\n", event.getHangoutLink());
