I have the below method:
public String tryGoogleAuthentication(String auth_token){
ContactsService contactsService = new ContactsService(".....");
contactsService.setUserToken(auth_token);
IFeed feed = null;
try {
feed = contactsService.getFeed(new
URL("https://www.google.com/m8/feeds/
contacts/default/full?max-results=10000"), ContactFeed.class);
} catch (IOException e) {
e.printStackTrace();
return CONST.GOOGLE_AUTH_INVALID_TOKEN;
} catch (ServiceException e) {
e.printStackTrace();
return CONST.GOOGLE_AUTH_INVALID_TOKEN;
} catch (NullPointerException e) {
e.printStackTrace();
return CONST.GOOGLE_AUTH_INVALID_TOKEN;
}
if (feed == null)
return "";
String externalId = feed.getId();
IPerson person = feed.getAuthors().get(0);
String email = person.getEmail();
String name = person.getName();
String nameLang = person.getNameLang();
System.out.println("externalId: " + externalId);
System.out.println("email: " + email);
System.out.println("name: " + name);
System.out.println("nameLang: " + nameLang);
return CONST.STATUS_OK;
}
and I get the error:
