Hello "query.setMaxResults(20000);" only sets the maximum number of results,
I only have about 1200 registered contacts. Because default maximum result
is 25, raised to have a safety margin.
"or modify it to request only 1 contact as the only information you're
interested in is the number of contacts in the group which will be returned
either way."
How exactly I do this? if I ask just one contact, as I will answer only one
contact, correct?
Removed "query.setMaxResults (20000);" and this error occurred:
*java.lang.IllegalStateException: Uninitialized version registry*

The line where the error occurs is precisely that executes the query:
*ContactFeed resultado = servico.query(query, ContactFeed.class);*
I changed the number of request and the slowness continues. My code
currently looks like:
[code]
private Integer numeroDeContatos(String idGrupo) {
try {
URL feedURL = new URL("http://www.google.com/m8/feeds/contacts/";
+ usuarioCorrente + "/full");
Query query = new Query(feedURL);
query.setMaxResults(5000); // por default são 25 resultados.
query.setStringCustomParameter("group", idGrupo);
ContactFeed resultado = servico.query(query, ContactFeed.class);
return resultado.getTotalResults();
} catch (MalformedURLException e) {
throw new RuntimeException("URL inválida", e);
} catch (IOException e) {
throw new RuntimeException("Erro geral de I/O", e);
} catch (ServiceException e) {
throw new RuntimeException("Erro interno do serviço", e);
}
