Android工程中使用Google calendar API时 Query出错解决思路

   CalendarService myService = new CalendarService("CalendarTest-1");        try {              myService.setUserCredentials("username", "password");              System.out.println("Printing all events");              printAllEvents(myService);  //获得所有Events             dateRangeQuery(myService,DateTime.parseDate("2010-03-01"), DateTime                       .parseDate("2010-03-01"))   //查询指定日期Event     } catch (AuthenticationException e) {              e.printStackTrace();         } catch (MalformedURLException e) {              e.printStackTrace();         } catch (IOException e) {              e.printStackTrace();         } catch (ServiceException e) {             e.printStackTrace();         }       

  private  void dateRangeQuery(CalendarService service,        DateTime startTime, DateTime endTime)  {     CalendarQuery myQuery = new CalendarQuery(eventFeedUrl);      myQuery.setMinimumStartTime(startTime);      myQuery.setMaximumStartTime(endTime);      // Send the request and receive the response:      try {        CalendarEventFeed resultFeed = service.query(myQuery, CalendarEventFeed.class); //出错    } catch (IOException e) {        // TODO Auto-generated catch block        e.printStackTrace();    } catch (ServiceException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }  }
