Hier ein paar Samples fuer die Google API.

Java

Mit den Google Data APIs können Services von Google in Applikationen genutzt werden. Dokumentation.

Google Calendar

Sample mit Zugriff auf den Google Kalender. Die Termine werden alle aufgelistet. Click, um Java-Webstart zu starten. Der wesentliche Code findest du hier: GoogleCalendar.java.

Hier der Code:

package googlecalendarjava;

import com.google.gdata.client.calendar.CalendarService;
import com.google.gdata.data.calendar.CalendarEventEntry;
import com.google.gdata.data.calendar.CalendarEventFeed;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

public class GoogleCalendar {

   public List<String> getEvents(String username, String password) {

       List<String> result = new ArrayList<String>();

       try {
           StringBuffer url = new StringBuffer();
           url.append("http://www.google.com/calendar/feeds/");
           url.append(username);
           url.append("/private/full");

           URL feedUrl = new URL(url.toString());
           CalendarService myService = new CalendarService("exampleCo-exampleApp-1");
           myService.setUserCredentials(username,password);

           CalendarEventFeed queryResult = myService.getFeed(feedUrl, CalendarEventFeed.class);
           List<CalendarEventEntry> entries = queryResult.getEntries();
          
           for (CalendarEventEntry entry : entries) {
               StringBuffer entryString = new StringBuffer();

               //Titel 
               String title = entry.getTitle().getPlainText();
               entryString.append("Title: " + title);

               //Von und bis
               entryString.append(" Start: " + entry.getTimes().get(0).getStartTime());
               entryString.append(" End: " + entry.getTimes().get(0).getEndTime());

               entryString.append("\n");

               result.add(entryString.toString());
           }

       } catch (Exception e) {
           result.add("Error; " + e.getMessage());
       }
       return result;
   }
}

Google Calendar

Hier eine Klasse um die Events in einem Kalender aufzulisten:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Google.GData.Calendar;
using Google.GData.Client;
using Google.GData.Extensions;

namespace GoogleCalendarSample
{
   class GoogleCalendar
   {
       public List<String> GetEvents(string username, string password)
       {
           List<String> result = new List<string>();
           CalendarService myService = new CalendarService("exampleCo-exampleApp-1");
           myService.setUserCredentials(username, password);

           EventQuery query = new EventQuery();
           StringBuilder sb = new StringBuilder();
           sb.Append("http://www.google.com/calendar/feeds/");
           sb.Append(username);
           sb.Append("/private/full");
           query.Uri = new Uri(sb.ToString());
           EventFeed queryResult = myService.Query(query);
           foreach (EventEntry entry in queryResult.Entries)
           {
               StringBuilder stringBuilder = new StringBuilder();
               stringBuilder.Append("Title: " + entry.Title.Text);
               stringBuilder.Append(" Start: " + entry.Times[0].StartTime);
               stringBuilder.Append(" End: " + entry.Times[0].EndTime);
               stringBuilder.Append("\n");
               String stringToAdd = stringBuilder.ToString();
               result.Add(stringToAdd);
           }            
           return result;
        }
   }
}
