I am making an application that uploads images to server and updates its database to server in android while executing it, it shows an error
Connection to http://localhost refused
and many more errors, I researched this problem and found instead of providing the URL connection
http://localhost/... provide the link as http://10.0.2.2/...
and I did so but the problem is same more error is here:
E/org.apache.http.conn.HttpHostConnectException(4318): Connection to http://localhost refused

the code for file upload is:
public int uploadFile(ArrayList<String> sourceFileUri, String info, String latitude, String longitude, String id) throws IOException {
try {
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost("http://10.0.2.2/deliverysystem/order/add");
MultipartEntity entity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("returnformat", new StringBody("json"));
System.out.println(sourceFileUri.size());
for(int i=0;i<sourceFileUri.size();i++){
String sourceFile = sourceFileUri.get(i);
entity.addPart("uploaded_file"+(i+1), new FileBody(new File(sourceFile)));
}
entity.addPart("fld_delivery_id", new StringBody(id));
entity.addPart("fld_delivery_location", new StringBody(info));
entity.addPart("fld_latitude", new StringBody(latitude));
entity.addPart("fld_longitude", new StringBody(longitude));
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost, localContext);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse = reader.readLine();
return 1;
} catch (Exception e) {
if (dialog.isShowing())
dialog.dismiss();
Log.e(e.getClass().getName(), e.getMessage(), e);
return 1;
}
}
while debugging the code reaches up to:
httpPost.setEntity(entity);
and it shows exception after this line ie on this statement:
HttpResponse response = httpClient.execute(httpPost, localContext);
Could any one help me on this?

Two solutions for this error:
1. add this permission in your androidManifest.xml of your Android project
<uses-permission android:name="android.permission.INTERNET"/>
2. Turn on the Internet Connection of your device first.

if you are using emulator to run your app for local server. mention the local ip
as 10.0.2.2
and have to give Internet permission into your app :
<uses-permission android:name="android.permission.INTERNET" />

for wamp server use 10.0.2.2
for local host
e.g. 10.0.2.2/phpMyAdmin
and for tomcat use 10.0.2.2:8080/server

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!!

One of the basic and simple thing which leads to this error is: No Internet Connection
Turn on the Internet Connection of your device first.
(May be we'll forget to do so)

I had the similar issue, then I found out that wifi was not connected in my smartphone. After I turned on the wifi and connected to the similar network (with my laptop), there was another issue - laptop's firewall was blocking incoming connections. Once I fixed the firewall, I was able to communicate from my android app with the web service running on the laptop.

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>

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

<uses-permission android:name="android.permission.INTERNET"/>
add this tag above into AndroidManifest.xml of your Android project
,and it will be ok.

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
