Android java.net.UnknownHostException: Host is unresolved: server_address:443

I'm trying to get xml from server via https connection. If i do it with curl command

curl -k -A "Mozilla/4.0" https://username:password@server.com/test/infoxml.ashx

connection is successfull, but when i try it in java on android, it doesn't work. I'm using this code:

URL url = new URL("https://user:password@server.com");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", "Basic **********************");
conn.setRequestProperty("User-Agent", "Mozilla/4.0");
conn.setRequestProperty("Host", "server.com");
conn.setRequestProperty("Accept", "*/*");

InputStream content = conn.getInputStream();

As you can see, I set up headers based on verbose output of working curl command, which is as follows:

* About to connect() to server.com port 443 (#0)

I'm new to this secure connection stuff, so go easy on me :)

p.s. sorry for my bad English.

Try something like the following. For the rational behind the HttpRequestInterceptor see this blog post on "Http Basic Authentication with Android". I have not tried the code, but it is a conglomeration of working code that I have used along with the Basic Authentication part added.

SchemeRegistry supportedSchemes = new SchemeRegistry();
supportedSchemes.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
supportedSchemes.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));

HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF-8");
HttpProtocolParams.setUseExpectContinue(params, true);
HttpProtocolParams.setUserAgent(params, "Android App");

ClientConnectionManager connectionManager = new ThreadSafeClientConnManager(params, supportedSchemes);
AbstractHttpClient httpClient = new DefaultHttpClient(connectionManager, params);

HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() {
    @Override
    public void process(HttpRequest request, HttpContext context)
            throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);
        CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                ClientContext.CREDS_PROVIDER);
        HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);

        if (authState.getAuthScheme() == null) {
            AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());
            Credentials creds = credsProvider.getCredentials(authScope);
            if (creds != null) {
                authState.setAuthScheme(new BasicScheme());
                authState.setCredentials(creds);
            }
        }
    }
};

httpClient.addRequestInterceptor(preemptiveAuth, 0);

Credentials creds = new UsernamePasswordCredentials("username", "password");
httpClient.getCredentialsProvider().setCredentials(new AuthScope(null, -1, AuthScope.ANY_REALM), creds);

HttpHost host = new HttpHost("server.com", 443, "https");
HttpGet httpGet = new HttpGet("https://server.com/test/infoxml.ashx");
HttpResponse httpResponse = httpClient.execute(host, httpGet);

HttpEntity responseEntity = httpResponse.getEntity();
InputStream content = responseEntity.getContent();
