java - SignalR Android access localhost -

for reason cannot make make android app connect server (on localhost)

the problem (probably) not in code,the exact same code runs fine in simple java application

i invalidhttpstatuscodeexception

bad request - invalid hostname http error 400. request hostname invalid.

i tried using emulator ,genymotion(i changed ip http://192.168.56.1... )

java.util.concurrent.executionexception: microsoft.aspnet.signalr.client.transport.negotiationexception: there problem in negotiation server

i exception in httpclientransport.java ,line 76

@override public signalrfuture<negotiationresponse> negotiate(final connectionbase connection) {     log("start negotiation server", loglevel.information);      string url = connection.geturl() + "negotiate" + transporthelper.getnegotiatequerystring(connection);      request = new request(constants.http_get);     get.seturl(url);     get.setverb(constants.http_get);      connection.preparerequest(get);      final signalrfuture<negotiationresponse> negotiationfuture = new signalrfuture<negotiationresponse>();      log("execute request", loglevel.verbose);     httpconnectionfuture connectionfuture = mhttpconnection.execute(get, new responsecallback() {          public void onresponse(response response) {             try {                 log("response received", loglevel.verbose);                 throwoninvalidstatuscode(response);                  log("read response data end", loglevel.verbose);                 string negotiationcontent = response.readtoend();                  log("trigger onsuccess negotiation data: " + negotiationcontent, loglevel.verbose);                 negotiationfuture.setresult(new negotiationresponse(negotiationcontent, connection.getjsonparser()));              } catch (throwable e) {                 log(e);                 negotiationfuture.triggererror(new negotiationexception("there problem in negotiation server", e));             }         }     });      futurehelper.copyhandlers(connectionfuture, negotiationfuture);      return negotiationfuture; } 

if make request browser don't error

url=http://192.168.56.1:3227/signalr/signalr/negotiate?clientprotocol=1.3&connectiondata=%5b%7b%22name%22%3a%22myhub%22%7d%5d

the response is

in both cases can access other services on server problem related signalr

here entire code

sorry long post wanted give details have

when starting server using this:

http://localhost:3227 

changed to

http://192.168.56.1:3227 

and works...
