Android VPN connection java.net.UnknownHostException: Unable to resolve host "<url>" No address associated with hostname -


i trying connect server using vpn connection. connected pc using cisco anyconnect. when trying connect android code, find exception:

java.net.unknownhostexception: unable resolve host "<url>" no address associated hostname

here code:

try {           url endpoint = new url(sauthenticateurl);            httpurlconnection connection = (httpurlconnection) endpoint.openconnection();            if (connection.getresponsecode() == 200) {                     // success           } else {                    // error handling code goes here           }      } catch (ioexception e) {                e.printstacktrace();      }

the sauthenticateurl same used pc , works on it.

note have connected android device pc internet connection, both use same network now. , pc connected vpn server.

is there specific configuration should add able access vpn android?

first of all, of cases may occur issue.

  1. check permission , sure have following permissions in manifest :
    • android:name="android.permission.internet"
    • android:name="android.permission.access_network_state"
  2. try disconnect network , reconnect again.

  3. using schemeregistery below:

    keystore truststore = keystore.getinstance(keystore.getdefaulttype()); truststore.load(null, null);

    sslsocketfactory sf = new mysslsocketfactory(truststore); sf.sethostnameverifier(sslsocketfactory.allow_all_hostname_verifier);  httpparams params = new basichttpparams(); httpconnectionparams.setconnectiontimeout(params, 15000); httpconnectionparams.setsotimeout(params, 5000);  schemeregistry registry = new schemeregistry(); registry.register(new scheme("http", plainsocketfactory.getsocketfactory(), 80)); registry.register(new scheme("https", sf, 443));  clientconnectionmanager ccm = new threadsafeclientconnmanager(params, registry);  return new defaulthttpclient(ccm, params);`

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
