Answer 2

i was facing exactly the same issue and i made following changes to my URL after which it was working perfectly fine..

From:

http://localhost/Image4android/get_all_images.php

To:

http://192.168.1.2/Image4android/get_all_images.php

where the ip: 192.168.1.2 is IPv4 address. In windows Run > CMD > Ipconfig

Answer 3

I am using PHP for webservice and Android 4.x. device for connecting to the webservice. I had similar problem where, using 10.0.2.2 worked well with emulator but failed to connect from device. The solution that worked for me is: Find IP of your computer ... say 192.168.0.103 Find the port of your apache ... say 8080 Now open httpd.conf and locate following line Listen 127.0.0.1:8080 After this line add following Listen 192.168.0.103:8080 Thats it. Now if you use 192.168.0.103:8080 in your android code, it will connect!!

Answer 4

if you are using emulator to run your app for local server. mention the local ipas 10.0.2.2 and have to give Internet permission into your app :

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

Answer 5

When you test with device you want to add your PC ip address.

in pc run in cmd Ipconfig

in ubuntu run terminal ifconfig

Then use "http://your_pc_ip_address:8080/register" insted of using "http://10.0.2.2:8080/register"

in my pc = 192.168.1.3

and also add internet permission to Manifest

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

Answer 6

try adding the permission outside the application tag of the manifest in addition to the above mentioned answers of changing localhost to 10.0.2.2:8080
