Empty Http Call but no error
===

I'm trying to call a webservice with my application, but I get no error, the URL is the good one and return something (via the browser), but I get no content.

    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpGet httpget = new HttpGet(url);
        HttpResponse response = httpclient.execute(httpget);
        HttpEntity entity = response.getEntity();
        int lenght = (int) entity.getContentLength();
        is = entity.getContent();
    } catch (Exception e) {
        Log.e("log_tag", "Error in http connection" + e.toString());
    }

lenght is equal to -1 due to the empty response he receives

Does the response from the url need to be HTML ? Or anything I output can be grab by the HttpClient ?
