Today I am trying to write an android program to retrieve an XML data from localhost server. When running the program, the following error occurs:
E/ERR(1183): org.apache.http.conn.HttpHostConnectException: Connection to http://localhost refused
String
url = "http://localhost:100/test.xml";
try {
DefaultHttpClient
httpClient = new DefaultHttpClient();
HttpPost
httpPost = new HttpPost(url);
HttpResponse
httpResponse = httpClient.execute(httpPost);
}
catch
(ClientProtocolException e1) {
// TODO Auto-generated
catch block
e1.printStackTrace();
}
catch (IOException e1) {
// TODO Auto-generated
catch block
e1.printStackTrace();
}
Solution:
The Android emulator could not recognize the localhost and results in connection refused.
To resolve, we can change the localhost to the ip address 10.0.2.2 and try again, problem resolved.
e.g. String url = "http://10.0.2.2:100/test.xml";
