Android webservice GET request replies only a part of the XML response

问题

I'm trying to connect to a webservice offered by my heating at home. Putting the request URL into Chrome results in a complete XML file. Subsequently I tried to do the same programmatically with an Android application, which unfortunately only replies about the half of the XML file.

I already tried several attempts, amongst others a simple HttpConnection:

private void androidHttpConnect() {

    HttpURLConnection urlConnection=null;

    try {
        URL url = new URL("http://10.0.0.140:8080/user/menu");
        urlConnection = (HttpURLConnection) url.openConnection();
        BufferedInputStream in = new BufferedInputStream(
                urlConnection.getInputStream());

        Log.i("myapp",convertStreamToString(in));
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        urlConnection.disconnect();
    }
}

private String convertStreamToString(InputStream is) {
    return new Scanner(is).useDelimiter("\\A").next();
}

and the Android Http Client ...

HttpClient httpclient = AndroidHttpClient.newInstance("Android");
         HttpGet httpget = new HttpGet("http://10.0.0.140:8080/user/menu");
        HttpResponse response;
        try {
            response = httpclient.execute(httpget);
            HttpEntity entity = response.getEntity();

            if (entity != null) {
                long len = entity.getContentLength();
                Log.d("myapp", "content length "+len);
                if (len != -1) {
                    try {
                            Log.d("myapp", EntityUtils.toString(entity));
                        } catch (ParseException e) {
                            e.printStackTrace();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                } else {
                    // Stream content out
                }
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

Interestingly those attempts cut the result on different positions, even though they only differ in about 5 characters. At this position there is no special character and the XML is quite short.

Anyone any idea? I also tried to run it in a ASyncTask to ensure no interrupt by the UI thread, but without success.

Thanks for your help.

Finally found the solution by myself! The problem wasn't the request but the output in the LogCat. Logging every line separately obtained the desired full response!
