host name may not be null error in android

Question

I get the error "host name may not be null error " in my Android app.

This is my code:

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpPost httpost = new HttpPost("http://sub_domain.domain.com/service/api");
httpost.setHeader("Accept", "application/json");
httpost.setHeader("Content-type", "application/json");
ResponseHandler responseHandler = new BasicResponseHandler();
    try {
        httpclient.execute(httpost, responseHandler);
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

I use a sub-domain so I can't put 'www' in my url because it's another sub domain. I have Internet permission in my manifest file.

Any suggestions? Thanks!

Edit : It's impossible to access to this url with a GET method.

Without '_' in my subdomain, it's okay.

check the way url is encoded. any spaces should be eliminated.http://stackoverflow.com/questions/12537522/host-name-may-not-be-null-in-httpresponse-execute-for-android. Similar to your question — Raghunandan, Feb 27 '13 at 20:15
Have you tried it with a subdomain that doesn't have an underscore in it? They can cause problems. — Geobits, Feb 27 '13 at 20:26
no spaces in my url and with URLEncoder.encode(URL); I have the same issue. — Nuz, Feb 27 '13 at 20:26
