Connection to http://localhost:8080 refused in Android -

i trying consume rest service in android , getting following error:

org.apache.http.conn.httphostconnectexception: connection  http://localhost:8080 refused 

i have introduced permission: uses-permission android:name="android.permission.internet"
running code in emulator , works when try run in smartphone fails.

pd: when run in emulator use http://10.0.2.2:8080.

public boolean checkconnection(){     string res = "";     boolean serverup = false;      try {         httpclient client = new defaulthttpclient();         //httpget request = new httpget("http://10.0.2.2:8080/prueba_conexion");         httpget request = new httpget("http://localhost:8080/prueba_conexion");         httpresponse response = client.execute(request);          bufferedreader rd = new bufferedreader(new inputstreamreader(                 response.getentity().getcontent()));          string linea = "";         while ((linea = rd.readline()) != null) {             res += linea;         }          serverup = boolean.parseboolean(res);      } catch (clientprotocolexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     }     return serverup; } 

localhost doesnt work on phone, because refers phone itself.

you need local ip address , use instead ie. 192.168.something.something usually.
