I m implementing android app in that I m working on web api. Sometimes my app gets connected to webserver but sometimes it throws exception as java.net.UnknownHostException: Host is unresolved: webservername.com:80. I m fetching json response from api.

I m using fetching code as following:

    String queryResult  =   null;
    HttpClient client = new DefaultHttpClient();
    HttpGet request = new HttpGet();
    try {
            request.setURI(new URI(archiveQuery));
    } catch (URISyntaxException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    //HttpResponse response = client.execute(request, new BasicResponseHandler());
            try {
                queryResult =   client.execute(request, new BasicResponseHandler());
            }
            catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

Just restart adb, find adb.exe in your adt bundle and double click it. Some shit will happen on command prompt, and there you go, restart your emulator and it should work fine,

I think it's a DNS issue of your server, according to your comments. Sometimes you ping, sometimes you don't, but on your browser it always work? Surely it's a server connectivity issue.
