Srs,
O metodo post funciona quando uso o https://www.caelum.com.br/mobile, mas estou querendo testar num servidor localhost. Como faço isso? Segue abaixo a classe deste Curso Android e a classe do Curso WS rest ambos aqui do ALURA.
CLASSE1
public class ServidorProjetos {
public static void main(String[] args) throws IOException {
URI uri = URI.create("http://0.0.0.0:8080/");//peguei exemplo da internet
//URI uri = URI.create("http://localhost:8080/");
ResourceConfig config = new ResourceConfig().packages("br.com.alura.loja");
HttpServer server = GrizzlyHttpServerFactory.createHttpServer(uri, config);
System.out.println("Servidor rodando");
System.in.read();
server.stop();
}
}CLASSE2
@Path("entregas")
public class EntregaResource {
@GET
@Produces(MediaType.APPLICATION_JSON)
public String busca(Long id){
return new EntregaDAO().busca(1l).toJSON();
}

connection.connect();
int responseCode = connection.getResponseCode();
Log.i("WEBSERVICE", "Código de resposta : " + responseCode);
