Praticamente ho creato un REST webservice e ho creato delle api, ad esempio:

codice HTML:
http://localhost:8080/LdapServices/apildap/connection?HOST=ldap://192.168.1.46:389&BaseDN=cn=admin,dc=my,dc=it&Password=secret
se la provo via browser funziona perfettamente, ma se la provo da Android con:

codice:
RequestParams p = new RequestParams();        p.put("Password", mPassword);
        p.put("BaseDN", mBaseDN);
        p.put("HOST", mHost);
        
        
        AsyncHttpClient client = new AsyncHttpClient();
        Log.d("Network", "Step prima della chiamata get");


        client.get("http://localhost:8080/LdapServices/apildap/connection", p,
                new JsonHttpResponseHandler() {


                    @Override
                    public void onSuccess(JSONObject response) {
                        
                        showProgress(false);
                        
                        
                        System.out.println(response);
                    
                    }


                    @Override
                    public void onStart() {
                        showProgress(true);
                    }
                });
non mi restituisce nessun oggetto perchè la api va in errore, precisamente:
