You just have to use your local IP address:using the cmd command "ipconfig" and your server port number like this:

String webServiceUrl = "http://192.168.X.X:your_local_server_port/your_web_service_name.php"

And make sure you did set the internet permission in your project manifest

It's working perfectly for me

Good Luck

Replacing localhost with 10 0 2 2 is correct  but you can alsor replace localhost with your physical machine s ip it is better for debug purposes   Ofc  if ip is provided by dhcp you would have to change it each time     Good luck

localhost and 127 0 0 1 are both ways of saying  the current machine   So localhost on your PC is the PC and localhost on the android is the phone  Since your phone isn t running a webserver of course it will refuse the connection   You need to get the IP address of your machine  use ipconfig on windows to find out  and use that instead of 127 0 0 1  This may still not working depending on how your network firewalls are set up  But that is a completely different topic

If you are using localhost in your url and testing your application in emulator   simply you can replace system s ip address for localhost in the URL or you can use 10 0 2 2 instead of localhost   http   localhost webservice php to http   10 218 28 19 webservice php  Where 10 218 28 19 -  System s IP Address   or   http   localhost webservice php to http   10 0 2 2 webservice php

Since you have not specified you are connected to a server from the device or emulator so I guess you are using your application in the emulator   If you are referring your localhost on your system from the Android emulator then you have to use http   10 0 2 2 8080  Because Android emulator runs in a Virtual Machine therefore here 127 0 0 1 or localhost will be emulator s own loopback address   Refer  Emulator Networking
