Questions:

I am using xampp apache server to serve resources to the application from my machine. But i am getting the above error.

I got something on the google. pointing towards possible solution here
http://groups.google.com/group/android-beginners/browse_thread/thread/599a06416fb37b4a

What is the solution for the above problem?

How to&Answers:

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

Answer:

in android

Replace: String webServiceUrl = "http://localhost:8080/Service1.asmx"

With : String webServiceUrl = "http://10.0.2.2:8080/Service1.asmx"

Good luck!

Answer:

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.

Answer:

You just have to use your local (but real) IP address and port number like this:

String webServiceUrl = "http://192.168.X.X:your_virtual_server_port/your_service.php"

And make sure you did set the internet permission within the manifest

<uses-permission android:name="android.permission.INTERNET" />

Answer:

  1. Add Internet permission in Androidmanifest.xml file

uses-permission android:name=”android.permission.INTERNET

  1. Open cmd in windows
  2. type “ipconfig” then press enter
  3. find IPv4 Address. . . . . . . . . . . : 192.168.X.X
  4. use this URL
    http://192.168.X.X:your_virtual_server_port/your_service.php

Answer:

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

Answer:

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

Answer:

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!
